This paper discusses ongoing regulatory effects on efforts aimed at developing data infrastructures that assist test engineers in achieving information superiority and for maintaining their information, and on possible architectural frameworks for resolving the engineer’s need versus the regulatory requirements. Since current commercial-off-the-shelf (COTS) Enterprise Content Management (ECM) systems are targeted primarily at business environments such as back office applications, financial sectors, and manufacturing, these COTS systems do not provide sufficient focus for managing the unique aspects of flight test data and associated artifacts (documents, drawings, pretest data, etc.). This paper presents our ongoing efforts for deploying a storage infrastructure independent enterprise data management system for maintaining vital up-to-date information and for managing the archival of such data.

Today, the design of business enterprises is much more art than science. The complex structure and behavior of enterprises makes it difficult to untangle cause and effect amidst its components and their relationships. In order for managers to understand how an enterprise's architecture affects its behavior, they need tools and techniques to help them to manage the complexity of the enterprise. The practice of enterprise architecting continues to make advances in this area with reference frameworks that can be used to guide the decomposition and communication of enterprise architectures, but it does not provide tools to analyze the potential behavior of a proposed enterprise architecture. This research seeks to extend the practice of enterprise architecting by developing an approach for creating simulation models of enterprise architectures that can be used for analyzing the architectural factors affecting enterprise behavior and performance. This approach matches the content of each of the "views" of an enterprise architecture framework with a suitable simulation methodology such as discrete event modeling, agent based modeling, or system dynamics, and then integrates these individual simulations into a single hybrid simulation model. The resulting model is a powerful analysis tool that can be used for "what-if" behavioral analysis of enterprise architectures. This approach was applied to create a hybrid simulation model of the enterprise architecture of a real-world, large-scale aerospace enterprise.
(cont.) Simulation model analysis revealed potential misalignments between the current enterprise architecture and the established strategy of the enterprise. The simulation model was used to analyze enterprise behavior and suggest relatively minor changes to the enterprise architecture that could produce up to a 20% improvement in enterprise profitability without increasing resources to the enterprise.

The Department of Defense (DoD) presented a need to transform its Military Psychological Health Enterprise (MPHE) at multiple levels. It had been established that Enterprise Architecting would be used as an approach to perform the transformation but the way in which the multiple levels of the enterprise would be transformed had yet to be determined. The study began with an investigation into the current state of a low-level component of the MPHE. This investigation invoked Enterprise Architecting techniques to determine the as-is state of this low-level enterprise. Then, the results of the Enterprise Architecting analysis were combined with multilevel analysis techniques to create a framework that supported transformation of a complex, multilevel enterprise. It was determined that upon using Enterprise Architecting techniques to identify the dominant views of a low-level component of a multilevel Enterprise, the structure of the levels the enterprise as well as the interactions between the levels can be used to understand the impacts of decisions made at higher levels of the enterprise. In the specific case of the DoD MPHE, the dominant views were found to be Organization, Process, and Information. By investigating these dominant views in more depth, the ways in which its resources interacted while performing relevant tasks in this micro-level enterprise (Camp Lejeune MPHE) were determined. This information was transformed into objective data, which was then combined with the information about how the levels of the DoD MPHE interact to suggest a framework for modeling potential future states of the enterprise. This will support both the design and selection of a transformation plan for the enterprise. The descriptive application of the suggested framework provided in this thesis supports both the design and selection of a transformation plan for the enterprise.

Abstract (sommario):

Organizations make large investments in Information Systems (IS) expecting positive impacts to the organisation and its functions. Yet, there exists much controversy surrounding the 'potential' impacts of these systems, with some studies reporting broadly positive impacts of IS across organizations (Barua, Kriebel and Mukhopadhyay 1995; Barua and Lee 1997; Brynjolfsson and Hitt 1996; Lehr and Lichtenberg 1999; Mukherjee, Ray and Miller 2001), while others have shown nil or detrimental impacts (Attewell and Rule 1984; Brynjolfsson and Yang 1996; Cameron and Quinn 1988; Wilson 1993). Various authors have suggested that these conflicting results may be due to poor measurement - E.g. incomplete or inappropriate measures of success (DeLone and McLean 1992; Gable 1996; Melone 1990), lack of theoretical grounding and hence agreement on appropriate measures of success (Bonner 1995; Myers, Kappelman and Prybutok 1998), myopic focus on financial performance indicators (Ballantine, Bonner, Levy, Martin, Munro and Powell 1996; Kaplan and Norton 1996), weaknesses in survey instruments employed (Gable, Sedera and Chan 2003) (e.g., constructs lacking in validity), or (5) inappropriate data collection approach (Seddon, Staples, Patnayakuni and Bowtell 1999; Sedera and Gable 2004) (e.g., asking the wrong people, unrepresentative sample). Enterprise Systems (ES) have over the past decade emerged to be one of the most important developments in the corporate use of information technology. Anecdotal evidence reveals discontent with these large application software packages. Yet Enterprise System investments are seldom systematically evaluated post-implementation; the review process and measures typically being idiosyncratic and lacking credibility. Impacts resulting from 'Enterprise Systems' are particularly difficult to measure, with an Enterprise System entailing many users ranging from top executives to data entry operators; many applications that span the organization; and a diversity of capabilities and functionality. Despite the substantial investments made by organizations and the anecdotal evidence of discontent, systematic attempts to measure their success have been few. The primary objective of this research is to develop and test a standardized instrument for measuring ES-Success. Other related objectives of this research include: (1) to identify the dimensions and measures of ES-Success, (2) to validate a maximally generalizable measurement model and survey instrument for gauging ES-Success; (3) to develop an understanding of the state of Enterprise Systems using descriptive/comparative statistics, and (4) to identify and test an antecedent of ES-Success. With the above objectives, and in attention to the weaknesses identified in past IS-success research, this study follows and extends the 'research cycle' guidelines of Mackenzie and House (1979) and McGrath (1979). The research cycle entails two main phases: (1) an exploratory phase to develop the hypothesized measurement model, and (2) a confirmatory phase, to test the hypothesized measurement model against new data. The two surveys (termed as identification-survey and specification-survey) conducted in the exploratory phase of this research go beyond the activities recommended by Mackenzie and House (1979) and McGrath (1979). A third "confirmation-survey" was completed in the confirmatory phase of the research cycle. The three surveys gathered and analyzed data from six hundred (600) respondents. The purpose of the identification-survey was to discover the salient ES-Success dimensions and measures to include in an a-priori ES-Success model. Data from 137 respondents representing 27 Australian State Government Agencies that had implemented SAP R/3 in the late 1990s were analyzed. The analysis of identification-survey data yielded an a-priori model with 41 measures of 5 dimensions of ES-Success that provide a holistic view across the organization from strategic to operational levels. The specification-survey was employed to validate the a-priori ES-Success measurement model derived in the preceding identification-survey. Employing 310 responses from the same 27 public sector organizations, exploratory data analysis validated 27 measures of success pertaining to the 4 dimensions: information quality, system quality, individual impact and organizational impact. Data for testing the influence of an antecedent of ES-Success was simultaneously gathered during the specification-survey. This analysis, based on the Adaptive Structuration Theory (AST), investigated the influence of Knowledge Management Structures Adequacy (KMSA) on ES-Success. Preliminary results indicate a strong relationship between the Knowledge Management Structures Adequacy and ES-Success. The purpose of the confirmation-survey was to further validate the dimensions and measures of the ES-Success model, using new data, employing confirmatory statistical techniques. Data was gathered from 153 respondents across a large University that had implemented the Oracle Enterprise System, which facilitated further construct validity of the ES-Success measurement instrument was further established using Structural Equation Modeling (SEM).

Abstract (sommario):

A barrier to creating the platform-independent services envisioned by middleware-based development infrastructures is the level of performance robustness of the distributed applications created with them, in lieu of unpredictable variations in application behavior or in the resources available for satisfying user requests. Our goal is to improve the behavior locality of distributed applications and to prevent performance (mis-)behaviors from spilling across certain boundaries, since such spillage weakens behavior diagnoses and/or weakens or disables the effects of locally applied control or management methods. Toward these ends, we develop a novel software abstraction, termed {em isolation points} (I-points), which can be used to isolate application components or subsystems from each other. The main contributions of this work are Isolation Points, which are software abstractions for monitoring and understanding dynamic runtime behaviors to better isolation application components hence creating more robust distributed applications. Two concrete artifacts using I-points also developed in this thesis are: I(solation)-RMI and I(solatoin)-Queue. I-RMI demonstrates the utility of isolation points in J2EE's RMI-IIOP domain. I(solation)-Queue applies isolation points to message passing systems.

Abstract (sommario):

Today, with various technology and business standards, organizations face rapid changes in both internal and external environments. To be able to rapidly respond to such changing environments, integration of software systems has entered among the top priorities of many organizations. However, despite extended use of software integration, methods for estimating the business value of implementing such integration are still missing. Besides presenting a conceptual model to define the benefits of systems integration and related causal relationships, this study proposes a method for measuring such benefits in monetary terms. In particular, we demonstrate how a mathematical programming technique called Data Envelopment Analysis (DEA) can be used to evaluate the business value of software integration. Our method is illustrated using data from 12 organizations. The results indicate significant productivity gains by integrating software systems, which represent the value of software integration in organizations.

Abstract (sommario):

This research aimed at developing a research framework for the emerging field of enterprise systems engineering (ESE). The framework consists of an ESE definition, an ESE classification scheme, and an ESE process. This study views an enterprise as a system that creates value for its customers. Thus, developing the framework made use of system theory and IDEF methodologies. This study defined ESE as an engineering discipline that develops and applies systems theory and engineering techniques to specification, analysis, design, and implementation of an enterprise for its life cycle. The proposed ESE classification scheme breaks down an enterprise system into four elements. They are work, resources, decision, and information. Each enterprise element is specified with four system facets: strategy, competency, capacity, and structure. Each element-facet combination is subject to the engineering process of specification, analysis, design, and implementation, to achieve its pre-specified performance with respect to cost, time, quality, and benefit to the enterprise. This framework is intended for identifying research voids in the ESE discipline. It also helps to apply engineering and systems tools to this emerging field. It harnesses the relationships among various enterprise aspects and bridges the gap between engineering and management practices in an enterprise. The proposed ESE process is generic. It consists of a hierarchy of engineering activities presented in an IDEF0 model. Each activity is defined with its input, output, constraints, and mechanisms. The output of an ESE effort can be a partial or whole enterprise system design for its physical, managerial, and/or informational layers. The proposed ESE process is applicable to a new enterprise system design or an engineering change in an existing system. The long-term goal of this study aims at development of a scientific foundation for ESE research and development.

Abstract (sommario):

Enterprise resource planning (ERP) systems are considered the price of entry in today's business environment, and the number of small and medium-sized enterprises (SME) retiring legacy systems in favor of ERP systems is increasing exponentially. However, there is a lack of knowledge and awareness of ERP systems and their potential benefit and effect on performance, and overall value to SMEs. While ERP adoption costs and potential benefits are high, it is not apparent whether the end result will translate into higher productivity for SMEs. The goal of this study is to evaluate the benefits that accrue to a firm on adoption of an ERP system. In the context of SME, a production function approach is used to assess benefits over short and long term. In addition to the production function approach, a variety of related methods such as those based on stock market valuation and Tobin's Q are examined. Data were collected using the well-known CRSP datasets for SMEs. Analysis of data suggests that ERP implementation has no effect on firm's performance as measured by profit margins, Tobin's Q ratio and Labor productivity. In fact, ERP investments do not yield noticeable improvements on the performance measures even four years after implementation. Weaknesses in data suggest that the conclusion may be seen as tentative. The results of this research study, added value to the academic knowledge base by helping to understand the effects ERPs have on SMEs overall performance.

This research is motivated by the National Academy of Engineering and the Institute of Medicine's joint call for research in healthcare, promoting the application of principles, tools, and research from engineering disciplines, and complex systems in particular. In 2005, the US healthcare expenditure represented 16% of its GDP, with hospitals representing the largest source of expenditure, as is the case in the United Kingdom. Consequently, the strategies and operations developed and implemented by hospitals have a significant impact on healthcare. Today, it would be hard to find a hospital that is not implementing a Lean initiative or who isn't familiar with its concepts. However, more often than not, their approach has narrowly focused at a process level and inside individual service units like an emergency department. This research seeks to elevate traditionally narrow hospital definitions of lean and explore the broader concepts of lean enterprise principles and Enterprise Architecture (EA) while enhancing our knowledge of hospitals' socio-technical complexity and enriching an emerging EA Framework (EAF) developed at the Massachusetts Institute of Technology (MIT). Following an extensive longitudinal multidisciplinary literature review, a number of expert interviews, and preliminary empirical findings, an exploratory inductive and deductive hybrid study was designed to collect and concurrently analyze both qualitative and quantitative empirical data from multiple hospital settings over two main phases: * The first phase consisted of recorded interviews with the Chief Executive Officers of seven leading Massachusetts hospitals, who also provided sensitive internal strategy and operations documents. We explored how hospitals currently measure their hospital performance and how their explicit and implicit practices may be improved using lean enterprise principles. e The second phase comprised two in-depth case studies of large leading multidisciplinary hospitals, one located in the US and other in the United Kingdom, and included a total of 13 embedded units of analysis. Multiple sources of evidence were collected including electronic medical records, 54 interviews, observation, and internal documents. Findings were categorized and sorted, as phenomena of interest consistently emerged from the data, and enriched both the EAF, and our understanding of hospitals' EA in particular. In both in-depth hospital cases we found that their EA consisted of multiple internal architectural configurations, and in particular, those with an enriched understanding of EA had made decisions which had improved not only their local performance, but also enhanced their interactions with other service units upstream and downstream. Conversely, worse performing configurations demonstrated a limited understanding of their hospital's EA. We conclude that hospital performance can be improved through an enriched understanding of hospital EA. Furthermore, whilst considering all hospitals included in this study, we propose general and specific recommendations, as well as diagnostic questions, performance dimensions, and metrics, to assist senior hospital leaders in architecting and managing their enterprise.

Abstract (sommario):

This research project has established a new measurement model for User Empowerment as an enabler to Enterprise Systems 1 success. This study was inspired by the reported relationship between Empowerment and improved work outcomes. From this, it was hypothesised that empowering the users of Enterprise Systems during the implementation process would improve the reports of post implementation system success. A new related concept of system oriented User Empowerment was conceived. The outcomes of empowering users (increased worker effectiveness; (increased work satisfaction) conceptually resonates very closely to the outcomes of individual performance, quality of system outputs, goodness of system functionality and, on a broader level, effective use of the system to yield successful business outcomes. These latter outcomes represent the measures of Enterprise Systems success. Thus Empowerment as an independent variable, and Enterprise Systems success as a dependent variable, provided a launching platform for the study. The research model was built upon the existing research into Empowerment as articulated by Spreitzer (Spreitzer, 1996) and Thomas and Velthouse (Thomas & Velthouse, 1990) and its derived systems related construct of User Empowerment, first explored by Doll, Deng and Metts (Doll, Deng, & Metts, 2003). It used a current and validated measure of Enterprise Systems Success as developed by Gable, Sedera and Chan (Gable, Sedera, & Chan, 2003); this measure is a refinement of the Information Systems Success Model of DeLone and McLean (DeLone & McLean, 2002). 2 In order to test the relationships of Empowerment to (Enterprise) System success, the following research sub-problems were explored: * What types of Empowerment are relevant in the Enterprise System context? * Is User Empowerment different from Psychological Empowerment and if so, how? * What is the relationship between Psychological Empowerment and User Empowerment? * How can User Empowerment be measured? * What is the effect of Psychological Empowerment on Enterprise Systems success? * What is the effect of User Empowerment on Enterprise Systems success? This research project was a PhD study funded by the Australian Research Council through an industry linkage program. The industry partner in this project was SAP - the most successful vendor of Enterprise Systems. Although limited in analysis the study spanned across two industry sectors, with two Enterprise Systems (Oracle and SAP). This research was a multimethod study and involved both qualitative and quantitative phases. The multimethod included content analysis, survey, and case study. This research was led by an explorative research strategy and paid considerable attention to analysing each research method in relation to other research methods, and also in relation to the demands of the research problem. A comprehensive literature review established extant definitions and constructs for Psychological Empowerment, User Empowerment and, Enterprise Systems success. The literature review employed a formal qualitative research method, using open coding supported through the use of Nvivo, a Qualitative software package, in order to identify and derive key themes in the referent disciplines. The responses from the email survey of Information Systems researchers, and Enterprise Systems consultants were triangulated with the findings from the categorised literature review on Empowerment. This sub-study utilised WordStat software and the findings were presented at the QualIT conference (Sehgal & Stewart, 2006). Drawing from the existing perspectives on Empowerment a contextbased perspective on Empowerment was proposed by the researcher. From this work, a new working definition of (User) Empowerment was derived. This construct proposed that User Empowerment involved Computer Self-efficacy, Perceived Usefulness, Intrinsic Motivation, User Autonomy, and Problem-solving and Decision support. Psychological Empowerment involves Meaning, Self-determination, Competence, and Impact. The research project then empirically tested the relationship of both Psychological Empowerment and User Empowerment to Enterprise Systems success using a quantitative enquiry. The new User Empowerment construct was statistically tested for validity and reliability. This quantitative study found no statistical evidence for a relationship between Psychological Empowerment and Enterprise Systems success. The study findings suggest significant statistical evidence for a relationship between User Empowerment and Enterprise Systems success. Statistical analysis showed that the construct for User Empowerment was different from the construct of Enterprise Systems success. These relationships held regardless of the level of the user: senior management, operational, end users or technical. This phase of the study was presented at the Americas Conference of Information Systems (Sehgal & Stewart, 2004). This exploratory survey was followed by another industry based case study, which confirmed the results for a different industry sector and different Enterprise System. This latter study was used in an independent confirmatory factor analysis of the Enterprise Systems success measurement which was presented at the Americas Conference on Information Systems (Sehgal & Stewart, 2004) and International Conference on Information Systems (Sedera, Gable, & Chan, 2004) by fellow researchers. This research has demonstrated that User Empowerment, rather than Psychological Empowerment was significantly related to Enterprise Systems Success. The study findings identified potentially significant benefits to the Enterprise System implementing organisations as well as the Enterprise System vendor from empowering Enterprise System users. Of the reported benefits one of the relevant one was improved and positive reports about the implemented Enterprise System. Further, the study highlights the importance of context when measuring a construct such as Empowerment. There are clear practical implications for the research outcomes. These include a recommendation that training programs should ensure that users have a high degree of computer self-efficacy when using the enterprise system. The validated User Empowerment instrument will be utilised as a diagnostic tool for organisational readiness prior to an ES implementation. This would assist in benchmarking the level of empowerment and predicted Enterprise Systems success. Future research will explore the effects of an Enterprise System on the components of User Empowerment as it is conjectured that there is a reciprocal relationship between the system and user attributes of Computer Self-efficacy, Problem-solving Decision Support, and understanding of business logic.

Psychological Empowerment involves Meaning, Self-determination, Competence, and Impact. The research project then empirically tested the relationship of both Psychological Empowerment and User Empowerment to Enterprise Systems success using a quantitative enquiry. The new User Empowerment construct was statistically tested for validity and reliability. This quantitative study found no statistical evidence for a relationship between Psychological Empowerment and Enterprise Systems success. The study findings suggest significant statistical evidence for a relationship between User Empowerment and Enterprise Systems success. Statistical analysis showed that the construct for User Empowerment was different from the construct of Enterprise Systems success. These relationships held regardless of the level of the user: senior management, operational, end users or technical. This phase of the study was presented at the Americas Conference of Information Systems (Sehgal & Stewart, 2004). This exploratory survey was followed by another industry based case study, which confirmed the results for a different industry sector and different Enterprise System. This latter study was used in an independent confirmatory factor analysis of the Enterprise Systems success measurement which was presented at the Americas Conference on Information Systems (Sehgal & Stewart, 2004) and International Conference on Information Systems (Sedera, Gable, & Chan, 2004) by fellow researchers. This research has demonstrated that User Empowerment, rather than Psychological Empowerment was significantly related to Enterprise Systems Success. The study findings identified potentially significant benefits to the Enterprise System implementing organisations as well as the Enterprise System vendor from empowering Enterprise System users. Of the reported benefits one of the relevant one was improved and positive reports about the implemented Enterprise System. Further, the study highlights the importance of context when measuring a construct such as Empowerment. There are clear practical implications for the research outcomes. These include a recommendation that training programs should ensure that users have a high degree of computer self-efficacy when using the enterprise system. The validated User Empowerment instrument will be utilised as a diagnostic tool for organisational readiness prior to an ES implementation. This would assist in benchmarking the level of empowerment and predicted Enterprise Systems success. Future research will explore the effects of an Enterprise System on the components of User Empowerment as it is conjectured that there is a reciprocal relationship between the system and user attributes of Computer Self-efficacy, Problem-solving Decision Support, and understanding of business logic.

There are several technological solutions available in the market to help organizations with information security breach detection and prevention such as intrusion detection and prevention systems, antivirus software, firewalls, and spam filters. There is no doubt in the fact that significant progress has been made in the technological side of information security. However, when we study causes of information security breaches, we find that a significant number are caused by non-technical reasons such as social engineering, theft of computing device or portable hard drive, human behavior, and human error. This leads us to conclude that information security should not be viewed through technology perspective only. Instead, a more holistic approach is required. This thesis provides a systems approach towards information security management and include technological, management and social aspects. This thesis starts with introduction especially background and motivation of the author, followed by literature research. Next, Enterprise Information Security Management Framework is presented leading to estimation of an organization's information security management maturity-level. Finally, conclusion and potential future work are presented.

Abstract (sommario):

Enterprise architecture frameworks (EAFs) have been used to plan and manage large-scale enterprise deployments for more than four decades. EAFs are important tools used by systems engineers and are integral to characterize enterprise information architectures. They are increasingly being used as a proxy for managing entire organizations – enterprises. Enterprises represent complex, multi-disciplinary, socio-technical systems. They are ubiquitous, and involve and affect a vast number of humans every day. However, as inter-disciplinary tools for the management of the enterprise, there are certain limitations to the efficacy of existing enterprise architecture frameworks. The effective management of enterprises presents significant challenge and opportunity for the systems engineering community. This research discusses the limitations of, and proposes enhancements to, existing EAFs, based on research into extant business management frameworks. An historical perspective is provided on both systems engineering and business enterprise domain frameworks. Research into the common elements of successful business management frameworks confirms the limitations of existing systems engineering frameworks and suggests key additions for enhanced efficacy. The applicability and relevance of enhancing extant enterprise architectures with elements from extant business frameworks is examined. Finally, recommendations are made for enhancements to extant frameworks and suggestions advanced on future research into efficacy. This dissertation concludes with implications of these findings for systems engineers engaged in enterprise architecture and enterprise transformation efforts and a recommendation that systems engineers take a more holistic approach in their enterprise architecture and enterprise transformation efforts.

Historically, 70% of change initiatives in organizations and businesses fail. Change involves people. Throughout decades, as the generations change, we've seen a major change in the leader's approach and the medium they have used to connect with people. It is predicted that enterprise social media will become the main communications channel for 20% of business users by 2014. Investigation in this thesis shows the extent to which corporate leaders have used enterprise social media to bring a change in an organization. This research is an examination of how enterprise social media can deliver value in bringing an enterprise transformation. Fundamentals that have been laid out by Dr. Kotter to implement change in the organizations by the corporate leaders still hold. This thesis includes a practical examination of the effectiveness of using enterprise social media for each of the Dr. Kotter's 8-stages for leading change. To investigate the impact of enterprise social media in enterprise transformation, several full scale and brief interviews were conducted with key stakeholders in small, medium, and large scaled organizations. In addition to the standard Lean Advancement Initiative (LAI) suite of tools, the effectiveness of social media was evaluated in various stages using Kaplan's Balanced Scorecard, Force Field Analysis, Matrix Scorecard, System Dynamics Model, and a Weighted Scoring Card. Analysis suggests that based on the existing set of enterprise social tools, enterprise social media can play a key role in 3 of the 8 steps of leading change described by Dr. Kotter. Currently, enterprise social media can provide limited advantages in 5 of the 8 steps of leading change. Going forward, with the emerging set of enterprise social tools that are more integrated into business processes, the role of enterprise social media in bringing an enterprise transformation is expected to increase significantly.

Abstract (sommario):

Enterprise systems, such as enterprise resource planning and customer relationship management are widely used in corporate sectors and are notoriously large and monolithic. They are challenging to decouple because they manage asynchronous, user-driven business processes and business objects (BOs) having complex structural relationships. This thesis presents the remodularization technique combined with novel microservice patterns which utilizes both semantic properties of enterprise systems, i.e., BO structure, together with syntactic features of their code, i.e., methods and interactions, for identifying suitable parts of enterprise systems which can be run as fine-grained microservices in highly scalable Cloud systems while achieving high performance characteristics.

Abstract (sommario):

In order to remain competitive, the integration of their information systems is an imperative for many large organisations. Applications that originally have been developed independently are now required to interoperate to support new or different functions of the enterprise. Although the mechanisms for application interoperation exist provided by the technology, due to the sheer number and complexity of the running systems, integration solutions � centralised or distributed�appropriate at the local level do not translate successfully to the whole enterprise. Centralised integration approaches often satisfy only some of the integration requirements, they are very expensive, and are fraught with danger since they imply an �all or nothing� approach. Distributed approaches, on the other hand, suffer from complexity and scalability problems as the number of system interfaces to be implemented and the number of execution-time invocations grows with the number of component applications. This dissertation makes a contribution to the field of Enterprise Application Integration (EAI) within the framework of distributed systems technology. Based on real-life case studies experience, we present here a federated approach that controls the size and complexity of the integration effort by reusing existing systems as much as possible and reducing the number of interacting applications. Only selected local elements are exposed to the organisational milieu, and a consistent supporting infrastructure is provided to make systems interactions possible. Our approach provides a flexible and scalable strategy to enterprise integration, avoiding the shortcomings of traditional approaches. We respect existing organisational structures, and demonstrate how appropriate federation infrastructure and protocols enable the interoperation of existing systems. The three main facets of enterprise knowledge are systematically incorporated into the integration effort: a) by the use of domain ontologies to support data integration; b) by the development of a methodology to include business rules; and c) by the development of FEW, a federated workflow model to implement the business processes of the organisation.

Abstract (sommario):

Enterprise models are usually developed with ambition to capture the current or desired situation in enterprises with respect to performed or planned processes, organizational structure (including organization units, roles and competences), products or services produced and IT systems available in the enterprise.The above aspects are mutually reflective. Such enterprise models are often represented in formal modeling languages, like UEML (Unified Enterprise Modeling Language) or GEM (General Entity Manipulator) language allowing for the development of applications, which interprets or compute them. Enterprise ontologies basically allow the representation of the same aspects of an enterprise (processes, organizational structure, products and systems). However, enterprise ontologies use another representation (like OWL- Web Ontology Language) and often are developed for other application purposes than enterprise model. The objective of this thesis is to develop strategies for transforming enterprise models into enterprise ontologies. There should be maximum preservation of semantics and minimum loss of information during the process of transformation. On the basis of meta-model (model to model) transformation, we propose three elements mapping approaches. Each approach has a number of elements mapping rules. After comparative study the best suitable approach according to objective of this thesis is selected for implementation purpose. From a technical perspective, a tool named “EM2EO” is developed, which accepts an enterprise model as input and produces ontology as output.

Abstract (sommario):

Risk Management and, more specifically, risk "abuse" in aerospace programs are examined. The value of each risk item considered in a program is directly linked to the ability to reduce wasted effort and time. The working hypothesis of this thesis is that not all risk items are formally reported and/or followed through the formal risk process. It is also believed that risk levels are often under or overestimated. This results in an improper monitoring of the health of the program, and potential hidden costs to the customer. Corrective actions are recommended. This study has been performed as a part of a larger effort conducted by the Lean Aerospace Initiative. The present student studied risk abuse at a large aerospace company and teamed with a PhD candidate from Massachusetts Institute of Technology (MIT) who studied Risk Management in the Enterprise Organization.

Abstract (sommario):

Contemporary enterprises depend to great extent on software systems. During the past decades the number of systems has been constantly increasing and these systems have become more integrated with one another. This has lead to a growing complexity in managing software systems and their environment. At the same time business environments today need to progress and change rapidly to keep up with evolving markets. As the business processes change, the systems need to be modified in order to continue supporting the processes. The complexity increase and growing demand for rapid change makes the management of enterprise systems a very important issue. In order to achieve effective and efficient management, it is essential to be able to analyze the system modifiability (i.e. estimate the future change cost). This is addressed in the thesis by employing architectural models. The contribution of this thesis is a method for software system modifiability analysis using enterprise architecture models. The contribution includes an enterprise architecture analysis formalism, a modifiability metamodel (i.e. a modeling language), and a method for creating metamodels. The proposed approach allows IT-decision makers to model and analyze change projects. By doing so, high-quality decision support regarding change project costs is received. This thesis is a composite thesis consisting of five papers and an introduction. Paper A evaluatesa number of analysis formalisms and proposes extended influence diagrams to be employed for enterprise architecture analysis. Paper B presents the first version of the modifiability metamodel. InPaper C, a method for creating enterprise architecture metamodels is proposed. This method aims to be general, i.e. can be employed for other IT-related quality analyses such as interoperability, security, and availability. The paper does however use modifiability as a running case. The second version of the modifiability metamodel for change project cost estimation is fully described in Paper D. Finally, Paper E validates the proposed method and metamodel by surveying 110 experts and studying 21 change projects at four large Nordic companies. The validation indicates that the method and metamodel are useful, contain the right set of elements and provide good estimation capabilities.

Abstract (sommario):

Small and Medium-Sized Enterprises (SMEs) are implementing Enterprise Resource Planning (ERP) systems because they promise significant benefits. However, the majority of ERP deployments rarely meet user expectations and often do not yield expected benefits. As a result, the failure rate of ERP implementations at SMEs is estimated to be between 40 and 60 percent. This high rate of failure, together with the resultant impact on SMEs and the consequences for national development is a cause for concern. In order to address this concern, this study aims to explore how SMEs develop their business cases, as well as how the benefits, risks and costs of ERP systems are realised in SMEs. Companies need a clear vision and convincing reasons when they adopt ERP systems. The study used the qualitative research method. Cases from South Africa and Zimbabwe were investigated in a cross-sectional study. Data was collected through semi-structured interviews and analysed using elements of thematic data analysis, grounded theory, and a general inductive approach to analysis. The Design Reality Gap Model formed a theoretical base and was used as lens for data collection and analysis.

The focus of Bank of America's change management initiatives has shifted away from acquiring and integrating new businesses, a process it calls transition, and towards internal enterprise transformation through a process the Bank calls transformation. One significant change management initiative currently underway is the California Northwest (CANW) transformation. The focus of the CANW initiative is to transfer the Bank's retail banking platform and accounts in California, Idaho, and Washington to the Model banking platform that it maintains across the rest of its enterprise. This thesis, using the California Northwest transformation as a case study, is an enterprise systems evaluation of change management practices at Bank of America. MIT Lean Advancement Initiative (LAI)'s Enterprise Strategic Analysis and Transformation (ESAT) methodology is used as a framework to evaluate the consideration of CANW stakeholders and the alignment of their needs with the CANW goals, processes, metrics, and strategic objectives. INCOSE's framework for writing quality system requirements is further applied to the California Northwest transformation goals. The result of this systems analysis is that while the set of strategic objectives is complete, additional processes, stakeholder values, and metrics need to be identified or developed. Although the set of CANW strategic objectives / goals is complete and all key objectives appear to have been included, the wording of individual goals needs to be clarified and the change management team must review each goal to ensure that it is both necessary and attainable. The second element of the research looks towards change management practices as a whole at Bank of America to identify whether BAC's transformation process is complete and effective. The study reveals that Bank of America should take a stakeholder centric view and consider the needs of all stakeholders to gain "buy-in" from all parties so as to create an "all hands on deck" environment for transformation initiatives. Other recommended actions include announcing change initiatives publically when possible, back-checking of actions by all parties, maintaining a single message, and adopting a standardization vs. transformation mindset.

Enterprise transformation is a dynamic process that builds upon and affects organizational processes. Organizational assessment plays critical role in planning and execution of enterprise transformation. It allows the assessment of an enterprise's current capabilities as well as for identification and prioritization of improvements needed to drive the enterprise transformation process. Despite the benefits that organizational assessment has to offer, many organizations fail to exploit them due to unfavorable organizational culture, unsatisfactory assessment processes or mismatch between assessment tool and broader transformation approach. This thesis focuses mainly on a model of organizational assessment and how it can be improved to better support enterprise transformation. We argue that the assessment process spans beyond performing the assessment itself. For the assessment to provide the expected benefit, organizations must first of all create an environment ensuring a clear understanding of the role assessment plays in the enterprise transformation process. To this end they must promote open and frequent discussion about the current state of the enterprise and future goals. The assessment process must be carefully planned to ensure it runs effectively and efficiently and that assessment results are accurate and reliable. Assessment results must be analyzed and turned into specific recommendations and action plans. At the same time, the assessment process itself must be evaluated and adjusted, if necessary, for the next assessment cycle. Based on literature review and case studies of five large aerospace companies, we recommend a five-phase assessment process model that includes mechanisms to change organizational behavior through pre-assessment phases. It also allows for adjustment of the assessment process itself based on the results and experience of participants so that it better suits the organization's needs and practices.

Abstract (sommario):

There exist today a large number of enterprise models or enterprise modelling approaches. In a study of standards and project developed models there are two approaches: CIMOSA “The Open Systems Architecture for CIM” and GERAM, “Generalised Enterprise Reference Architecture”, which show a system orientation that can be further followed as interesting research topics for a system theory oriented approach for enterprise models.

In the selection of system theories, manufacturing system theory is interesting and promising to adapt or extend to further synthesising and usage of enterprise models.

Today the design and creation of an enterprise model are based on a given architecture and available even though this is not always practical. When it comes to execution and operational phases of the model, the possibilities are more limited.

Manufacturing system theory [Bjørke 1995] was developed to describe system-oriented approaches to manufacturing systems including product configuration and design processes. This includes a large number of disciplines like mechanics, cybernetics, material science etc. on the physical side and planning activities, economical aspects and optimisation processes on the human side. The theory is based on geometry as the foundation and the methods within the theory are related to concepts of connections. The analysis of the manufacturing systems is the prime area for the usage of this theory and is important in order to bring a science base into manufacturing. But the theory can be used in a more generic way.

The theory of logic [Møller 1995] relates also to the concept of connections, being expressed as logic arguments. The theory is generic and has been applied to different model approaches e.g. product configuration, scheduling and planning, railway logic control. This theory of logic is also fully applicable in manufacturing system theory. The theory of logic and the manufacturing systems theory are both based on geometry or more precisely expressed the geometric funded theory of connections.

The main requirement for the enterprise model architecture to be used together with the theory of logic is that it can be divided into a 3D orthogonal space with unique defined axis. In this work a 3D space based upon product, process and organisational axis is preferred, also called the PPO-model. In this study combination of the enterprise modelling architecture, GERAM ISO 15704, and the theory of logic are used to show how systems theory can be used in control and management of operational phases of enterprise models. The usage of logic theory within enterprise modelling gives solutions on management and control issues in an operational phase of the product model. If is important to emphasis that this is not an approach for populating or transfer of operative data into a model. The integration of theses theories are illustrated through examples that show modelled entities of an enterprise in operation within areas of:

- Execution of operative manufacturing unit

- Organisational and strategic issues

- Enterprise planning with aspects of uncertainty

An own PPO model for feature based integration within product design and process planning has been developed to show that alternative more simple and detailed architectures also can be used.

Abstract (sommario):

During the 1990s, many organizations across the globe migrated existing information systems to Enterprise Systems (ES) packages, which promised both business and technical solutions to their existing sets of problems. However, ES implementations have gained notoriety for not meeting budgeted expenditures and schedules. Such events have warranted academic research to gain an understanding about the role of ES packages and the importance of ES implementation. A large number of academic researchers have adopted a variance approach to examine ES implementation. As a result they have identified a range of critical success factors said to be influential in achieving successful implementation of ES packages. An alternate perspective for researching ES implementation is the process approach but this has remained largely neglected in academic debates. Furthermore, it has still not been possible for researchers or practitioners to understand the degree to which specific critical success factors, or other considerations, might be influential in any given ES implementation, either pre- or post-project. This research therefore adopts the process approach to examine ES implementations. The process approach is focused on explaining an outcome, given a set of activities. This research draws upon the work of Markus and Tanis (2000) and O�Leary (2000), who have established frameworks to explain an outcome (success or failure) of ES implementations. In addition, this research draws on the work of Davenport (2000) and Brehm et al. (2001), who have established models that outline activities related to configuration of business and software processes during implementation of ES packages. To enable this inquiry, a single case study (site) was chosen, to expose the actions and events that transpired during the implementation of an ES package. This research concludes that the framework of O�Leary (2000) is better suited to explain the outcome of an ES Implementation than the framework of Markus and Tanis (2000). The framework of Markus and Tanis (2000) was found to be useful in understanding the implementation process of an ES package. In addition, this research developed a novel model that portrays a comprehensive set of activities, undertaken by the case organization during the configuration of business and software processes. This model traversed the 'High-Level', 'Detailed Development' and 'Implementation' stages of the configuration process. It is asserted that this model is a significant improvement when compared to models presented by Davenport (2000) and Brehm et al. (2001). This research also explored some of the issues of the case study that did not fit neatly into the existing theoretic frameworks employed. Six issues emerged in this regard; 'Selection of industry specific ES package solution'; 'Selection of Proven Implementation Partner'; 'Project Planning and Management'; 'Incremental Implementation Strategy'; 'Ownership of the ES Project' and 'Selection of Best Practice Business Processes'. It is contended that each have played a critical role in the successful deployment of the ES package at this case site.

Abstract (sommario):

The purpose of this thesis work was to find out how Enterprise Resource Planning systems (ERP) have been used in the healthcare sector and how ERP systems could be used to improve the healthcare services. Some findings were discussed and recommendations were made about how ERP systems could be used in the healthcare sector. The thesis was written using literature review research method. Literature is the study that involves gathering and studying earlier knowledge about a specific topic of interest. Various documents were studied regarding the use of ERP in healthcare institutions. Literature review was used to show how ERP systems have been used previously in some healthcare institutions and organisations. Based on the literature used in this study, ERP systems have not been widely reported to have been used in the healthcare sector. On the other hand, other findings showed that ERP systems could be used in the healthcare sector to improve their quality of services. Therefore, if ERP systems were successfully implemented in a healthcare organisations, it was suggested that it would bring about significant change especially in finance, human resources, and capacity, revenue and admission resource functions. ERP systems could also improve profitability and services in the healthcare organisations.

A tecnologia de informação e, mais especificamente, os Enterprise Systems (ESs), têm recebido enorme atenção e investimentos maciços nas organizações. Por se tratar de uma tecnologia relativamente nova, os estudos sobre ESs não têm claro os seus impactos na transformação organizacional em termos das pessoas e cultura numa perspectiva sociotécnica, estruturalista e humanista. Por meio de um estudo qualitativo fruto de bricolagem com vários ambientes de análise, características de sujeitos e com a ferramenta de análise do conteúdo do discurso, puderam-se confirmar as hipóteses sobre os impactos dos ESs quanto à melhoria nas relações pessoa/pessoa, pessoa/alta gerência e pessoa/trabalho, base do levantamento 'Um Excelente Lugar para se Trabalhar', bem como, impactos em outras variáveis analisadas. O estudo estendeu-se um pouco mais e verificou as habilidades dos implantadores dos sistemas e desenvolvedores dos softwares, as características das empresas com relação à fase de maturidade evolutiva e os objetivos pouco claros de implantação dos ESs como fatores dificultadores de implantação, resultando em sub-utilização e resistência e perda de recursos. O trabalho realiza também uma ampla pesquisa bibliográfica que evidencia que ainda não há um grau médio de clareza sobre as reais características do fenômeno 'implantação de ES', suas justificativas, problemas, objetivos, fatores determinantes de sucesso, etc.

The study went further and verified the abilities of the people that implement the systems and develop software, the characteristics of companies related to evolution phase and the mistaken objectives of ESs implementation as factors that make the implementation more difficult, resulting on sub utilization, resistance and resources expended unnecessarily. The study also makes a wide bibliographic research that evidences that there is not a medium degree of understanding or theory about the real characteristics of the phenomenon 'ES implementation', its justifications, problems, objectives, factors that determine success, etc.

Abstract (sommario):

In recent years organizations developing information systems have started to demand that there should be an explicit connection between the rationale of the system developed and the system itself. In the "From Fuzzy to Formal" project an attempt to develop a methodology supporting this was made. Within the project a method called Enterprise Modeling was developed, aiming at creating this connection. This method contains five different sub-models. The sub-models are connected to each other by inter-model links. The models developed using EM are of high complexity. Therefore tool and repository support should be provided. To be flexible and extendible, such a tool set should be based upon a standardized meta-model. CDIF is an example of such a standard.

In this dissertation we develop a meta-model capable of capturing the information that is created using the Enterprise Modeling technique. We use the extensibility mechanism that is provided with the CDIF standard to extend the existing CDIF Integrated meta-model to support the models used in this work. We also develop a procedure supporting the mapping between the representations. Finally we discuss the functionality of a tool capable of supporting the work with the models.

Abstract (sommario):

Thesis (S.M.)--Massachusetts Institute of Technology, Engineering Systems Division, 2005.
Includes bibliographical references (p. 147-151).
The research contained in this thesis explores design attributes of the enterprise performance measurement system required for the transformation to the lean enterprise and its management. Arguments are made from the literature that successful deployment of the lean practices, across three different stages of the evolution of lean thinking, requires a supporting performance measurement system. The increase in scope of lean practices at each stage of the evolution increases the complexity in achieving synchronization across the enterprise subsystems. The research presents various attributes of the performance measurement system required at each stage and further derives the three key attributes for the design of the lean enterprise performance measurement system. These three attributes are: enterprise level stakeholder value measures, the causal relationships across performance measures at each level, and Uniform and consistent set of performance measures. A detailed case study of an aerospace and defense business of a multi-industry corporation which has embarked on a journey towards creating a lean enterprise is presented.
(cont.) It highlights several challenges in the transformation from the perspective of performance measurement. The key challenges identified are: First, disconnect between the performance measurement for the lean practices and regular business practices hinder the adoption of lean practices. This disconnect exists due to the existence of both legacy performance measures and the new measures. Second, lack of understanding of the cause-effect relationship between performance measures across different enterprise levels poses difficulty evaluating the impact of lean related efforts. Third, use of non-uniform performance measures across various enterprise subsystems leads to non-lean behavior. The theory underlying performance measurement is reviewed including the widely-accepted performance measurement frameworks suggested for the design of enterprise performance measurement system. Analysis of these frameworks reveals that none of the existing frameworks completely capture the desired attributes for the lean enterprise performance measurement system.
(cont.) To design the lean enterprise performance measurement system, this research suggests a conceptual design that explicates the use of various tools and techniques to address the critical attributes. To identify stakeholder value measures this design demonstrates the use of stakeholder value analysis. Use of system dynamics modeling and structural equation modeling is suggested to establish, validate and evolve the cause-effect relationships between performance measures. And, to maintain the uniform set of measures the creation of measures dictionary is explained. Further, research is needed to empirically validate the model as a means for successful transformation and management of the lean enterprise.

This paper reports results of a study done to understand the Enterprise Architecture (EA) landscape in Singapore Government Agencies, to gather some best practices in doing EA in these agencies, and to postulate how the Singapore Government might get more value out of EA. Firstly, this paper reviews the EA field on why EA is important and what are some key challenges EA practitioners face. Secondly, this paper reviews and analyzes data from a EA survey of 18 Singapore Government Agencies. The analysis is done by comparing against data from a similar survey collected from over 100 organizations worldwide. In addition, the analysis also draws upon EA research done by MIT's Center for Information System Research. Thirdly, this paper reviews best practices and a case study collected from a subset of the studied Singapore Government Agencies. This paper concludes by rounding up the key findings and hypothesizing that there is a need for stronger inhouse design/architecting capabilities within the Singapore Government.

An analysis was performed to investigate how enterprise architecting methods can be applied to an integrate test and evaluation enterprise and make it a more sustainable enterprise to provide continuous value in the face of an evolving DoD landscape. Enterprise sustainability is the ability of an enterprise to maintain economic viability through optimal resource management and preservation over an extended duration. Through the application of the eight lenses of enterprise architecting, it was found that a more holistic understanding of a Major Range and Test Facility Base (MRTFB) enterprise's current state could be achieved. This approach also supported identifying gaps that exist between the ability of the current-state MRTFB to deliver value and the value delivery that is required by its key stakeholders. The importance of expanding the information view of enterprise architecting to encompass the entire enterprise infrastructure was also studied. Through the expansion of the information view to an infrastructure view, a more complete depiction of the MRTFB enterprise was achieved. The specific importance of the energy infrastructure to a sustainable enterprise was also explored. Through the application of enterprise architecting, the interrelations between the energy infrastructure and the other views, such as processes, services, and knowledge, and the other supporting infrastructure components, such as facilities, land, physical assets, communication networks, and IT networks, can be established. It was found that the energy infrastructure is a core enabler for our technology-based society, and coupled with the current societal focus on green and sustainable energy provides a focal point for enterprises to leverage and initiate transformation efforts to align the energy infrastructure with larger enterprise strategic objectives.

The objective of this thesis is to depict the role of metrics in the evolving journey of enterprise transformation. To this end, three propositions are explored: (i) metrics and measurement systems drive transformation, (ii) employee engagement is a proxy to gauge transformation progress; and (iii) metric considerations enable enterprise transformation when systematically executed as part of a transformation roadmap. To explore this problem, the aerospace measurement community was consulted to help grasp a better understanding of the context in which transformation is currently defined and measured. Once the problem space was defined, the environment of doing research with the enterprise as the unit of analysis was described with the intent of exploring the role of metrics and transformation. In particular, the performance measurement literature helped identify tools and methods used to select metrics to enable decision making at the enterprise level. After this review, two case studies were performed, considering: (1) the implementation of a bottom-up measurement system to drive transformation and (2) the effect of a top-down corporate measurement system on the enterprise. The first case study revealed insights regarding the benefits and challenges of implementing measurement systems and highlighted the use of employee engagement as a proxy to measure enterprise transformation. In the second case study, contemporary measurement issues were discussed and mapped to an Eight Views of the Enterprise analysis to identify critical enterprise interactions.
(cont.) Ultimately, the Lean Advancement Initiative's Enterprise Transformation Roadmap was used as a method for depicting how performance measurement can help enable enterprise transformation. The implications of research in metrics for enterprise transformation span across thee areas: (1) the extensive literature reviews provide an academic contribution for performing enterprise and measurement research; (2) a common language and framework for exploring measurement problems is depicted for practitioners through the case study analysis; and (3) a connection between enterprise measurement and enterprise transformation is established to drive future transformation success.

Abstract (sommario):

The enterprise resource planning (ERP) implementation success rate is as low as 30%. Researchers have shown that ERP system implementation could cause both system and organization failures, affecting operations and stakeholders, alike. The technology-organization-environment conceptual framework was used to ground this qualitative single-case study. The purpose of the study was to explore strategies that a manufacturing firm in Ghana used to implement ERP systems successfully. The population of this case study comprised 5 stakeholders from a manufacturing firm in Ghana who had success in implementing an ERP system. Data were collected using face-to-face semistructured interviews and review of various corporate documents. Data analysis consisted of reviewing interview transcripts, compiling and organizing the data using an open-coding system, grouping the data into themes, and interpreting the meaning of the themes and data. Triangulation was used to strengthen the validity of the case study design. The primary themes that emerged from data analysis included critical strategies that organizational leaders can use to implement ERP systems successfully in Ghana-based manufacturing firms. Significant findings were that leaders who engage in ERP implementation should focus on managing human and technological infrastructure resources, seeking the support of top management, and designing and executing comprehensive change management plans. Implications for positive social change include the potential to increase funding for local schools, after-school youth programs, and philanthropic donations based on increased organizational profits generated from successful ERP leader implementation strategies.

Raytheon Company, a leader in aerospace and defense, has experienced tremendous growth through mergers and acquisitions. In particular, the company's Space and Airborne Systems (SAS) business unit was largely formed through acquisitions of E-Systems and Texas Instruments and a merger with Hughes Aircraft Company. To assimilate the legacy organizations, Raytheon and SAS have undertaken great efforts to work as "One Company." One such example has been to strive for an enterprise sales and operations planning process. Five years ago, Raytheon Space and Airborne Systems (SAS) Operations leaders recognized the need to be more proactive in comprehending forecasted business and subsequent impacts to SAS' manufacturing network. As a result, Program Requirements and Operations Planning (PROP) was born to enable improved supply chain planning for factory labor and capital resources. Over time, the complexity of SAS' business has proven to be a challenge for PROP to achieve its intended objectives.- This thesis considers PROP as an enterprise rather than a process and proposes re-designing it using a holistic enterprise architecting framework including a thorough examination of the current state of PROP with respect to seven architectural views (strategy, policy/external factors, process, organization, knowledge, IT, and products/services). A future state PROP design is derived from the analysis and then validated against a detailed case study of the Army's Firefinder radar product line manufactured at Raytheon's Forest, Mississippi facility.

Abstract (sommario):

The doctoral research project is titled ‘An Exploration of the Relationship of Organisational Culture and Enterprise System Success and sought to address the research gap identified in the literature between organisational culture literature and Information System success literature. This is a research project which is funded by the Australian Research Council in conjunction with industry. The industry sponsors for this research were SAP AG, SAP USA and SAP ANZ. The research project adopted a multi-method research design, grounded in practice, in order to surface any reported relationship between Enterprise Systems Success (ESS) and Organisational Culture (OC). A critical part of the study was to identify who could report on this relationship. Partners in implementation include internal change managers, internal consultants, vendor consultants and implementation partner consultants. Representatives from each of these constituents were interviewed, covering a range of industry sectors and Enterprise Systems vendor organisations. The first phase of the research was to qualitatively assess the perception of these participants on the role of culture to Enterprise Systems Success. This phase used open, axial and selective coding of the responses obtained in a semi-structured interview. The next phase of the research was to gather quantitative measures of Organisational Culture and Enterprise Systems Success. The Organisational Culture Assessment Inventory (OCAI) of Cameron and Quinn was selected to gather quantitative data on Organisational Culture. The Enterprise Systems Success instrument of Gable, Sedera and Chan was selected to measure the perception of ESS because of its proven reliability and validity. Each of these data sets were then analysed to determine if an association existed between the cultures of organisations that achieved most success with the Enterprise System as opposed to the culture types reported of organisations that achieved the least success with the ES. These findings then assisted in the development of a model of interaction between OC and ESS. Finally, the relationship of OC to ESS was explored in a rich case study of one large firm, to determine if the consultant’s reported relationships could be identified in the subcultures of the organisation. The key findings of this study were: 1. There was a relationship reported between culture type and success types. The findings a-e below represent findings using the culture definitions from Cameron & Quinn’s culture instrument: a. clan cultures which emphasised the behaviours of development of others were related to reports of ESS b. hierarchical cultures which emphasised the behaviours of control and coordination were related to reports of ESS c. hierarchical cultures which were poor in the execution of control and coordination were related to reports of the least success with ES d. market cultures which emphasised (internal) competitiveness were strongly related to reports of least success with ES e. literature attributes of continuous improvement (CI), flexibility (F) and innovation (I), which are often described as antecedents to innovation success and are found in the culture type of adhocracy, were reported as strongly related to success of ES, but the culture type of adhocracy was not reported as being present in the quantitative data describing consultant experiences with enterprises which had implemented ES. 2. that the literature supported theoretical reasons for the above findings 3. that these patterns of association were found in the case study. The research supports the proposition that there is a relationship between Organisational Culture type and ESS. Certain culture types practice behaviours that correspond to reported necessary behaviours for innovation success and ESS, whilst other culture types practice behaviours that correspond to behaviours for failure of innovation and of ES failure. A model of and explanation for this relationship was proposed as a result of the findings. Future research is now required to empirically test this model.

Abstract (sommario):

Enterprise information systems are increasingly being developed as distributed information systems. Quality attributes of distributed information systems, as in the centralised case, should be evaluated as early and as accurately as possible in the software engineering process. In particular, software measures associated with quality attributes of such systems should consider the characteristics of modern distributed technologies. Early design decisions have a deep impact on the implementation of distributed enterprise information systems and thus, on the ultimate quality of the software as an operational entity. Due to the fact that the distributed-software engineering process affords software engineers a number of design alternatives, it is important to develop tools and guidelines that can be used to assess and compare design artefacts quantitatively. This dissertation makes a contribution to the field of Software Engineering by proposing and evaluating software design measures for distributed enterprise information systems. In previous research, measures developed for distributed software have been focused in code attributes, and thus, only provide feedback towards the end of the software engineering process. In contrast, this thesis proposes a number of specific design measures that provide quantitative information before the implementation. These measures capture attributes of the structure and behaviour of distributed information systems that are deemed important to assess their quality attributes, based on the analysis of the problem domain. The measures were evaluated theoretically and empirically as part of a well defined methodology. On the one hand, we have followed a formal framework based on the theory of measurement, in order to carry out the theoretical validation of the proposed measures. On the other hand, the suitability of the measures, to be used as indicators of quality attributes, was evaluated empirically with a robust statistical technique for exploratory research. The data sets analysed were gathered after running several experiments and replications with a distributed enterprise information system. The results of the empirical evaluation show that most of the proposed measures are correlated to the quality attributes of interest, and that most of these measures may be used, individually or in combination, for the estimation of these quality attributes-namely efficiency, reliability and maintainability. The design of a distributed information system is modelled as a combination of its structure, which reflects static characteristics, and its behaviour, which captures complementary dynamic aspects. The behavioural measures showed slightly better individual and combined results than the structural measures in the experimentation. This was in line with our expectations, since the measures were evaluated as indicators of non-functional quality attributes of the operational system. On the other hand, the structural measures provide useful feedback that is available earlier in the software engineering process. Finally, we developed a prototype application to collect the proposed measures automatically and examined typical real-world scenarios where the measures may be used to make design decisions as part of the software engineering process.

Abstract (sommario):

Growing enterprises have growing amounts of information. Making sure that this information is easily accessible to its employees is not an easy task. For this task Enterprise Resource Planning (ERP) systems come in handy. However, the ERP systems contain lots of information and may be too complex to handle this information or may be too slow in sharing this information within the organisation. This thesis introduces a new solution for how mobile applications can connect to an ERP system by exploiting database synchronisation, which allows the employees to get the information wherever they are without the need to directly access the ERP system. There are three important questions in this thesis: how the ERP works, how to build a mobile application and, how to build a back end? By combining answers to these questions a whole system is built which is production ready and can copy data between the ERP system and the back end and show the information in a mobile application. The overarching goals were to build a system that could extract data from the ERP system into a proprietary back end and a mobile application that could synchronise with the back end. However, synchronisation between the mobile application and the back end was not implemented due to lack of time. The back end had to be able to scale up to 500 concurrent users and respond within 3 seconds, both of these goals were achieved. The mobile application that was built to display the information to the end user was built with usability in mind, since Netlight wanted a straightforward application that anyone could use. The mobile application was shown to have good usability. The results of this thesis project show that building systems around ERPs, instead of inside them, gives these systems the ability to scale, improved the implementation time, and reduced the company’s maintenance efforts.
Växande företag får mer och mer information. Att kunna se till att den informationen blir enkelt tillgänglig för alla inom företaget är inte nödvändigtvis lätt. Det är ofta det som affärssystem kan användas till, dock innehåller affärssystem väldigt mycket information och kan vara för komplexa för att enkelt kunna hantera information man är intresserad av. Det kan även uppstå problem i prestanda i och med storleken på affärssystemet. I det här examensarbetet föreslås ett nytt sätt för hur mobila applikationer kan integreras med affärssystem genom att synkronisera mot dess databas, vilket tillåter anställda att komma åt informationen vart de än befinner sig. I det här examensarbetet finns det tre olika delar som är intressanta, hur affärssystemet fungerar, hur man bygger en mobilapplikation och hur man bygger ett back end. Genom att kombinera kunskapen från ovan nämnda delar, byggdes systemet som är redo för produktion och kan synkronisera data från affärssystemet till back endet, samt att visa upp informationen i mobilapplikationen. De översiktliga målen var att bygga ett system som kunde extrahera data från affärssystemet till ett eget byggt back end och en mobilapplikation som kunde synkronisera med detta back end. Dock blev synkroniseringen mellan mobilapplikationen och back endet aldrig implementerat. Back endet skulle även kunna skala upp till 500 samtidiga användare och då kunna svara inom 3 sekunder, vilket man lyckades med. Mobilapplikationen som byggdes för att visa information byggdes med användbarhet i tankarna, eftersom Netlight ville ha en enkel mobilapplikation som vem som helst skulle kunna använda. Mobilapplikationen analyserades fram till att vara användarvänlig. Detta examensarbete visar på att det går att bygga system runt affärssystem istället för att bygga dem i affärssystemen, vilket möjliggör att systemet kan skala upp bättre, mindre tid för implementation samt mindre underhåll.

Abstract (sommario):

Although new methods of information systems engineering are being researched and developed, they are empirical in nature. The problem domain knowledge acquisition process relies heavily on the system analyst and user; therefore it is not clear whether the knowledge of the problem domain is comprehensive. This may lead to occurrence of logical gaps, misinterpretation of system requirements, thus causing issues for project. The research work is meant to develop new IS engineering method that will allow validation of the problem domain knowledge against formal criteria. In order to create such method basic principles of Knowledge Based ISE and Model Driven ISE were combined. By combining the two approaches Knowledge Based MDA method was created that extends traditional MDA with Enterprise Model. During the research Knowledge Based MDA tool’s prototype, that is capable of partly automating Knowledge Based MDA process, was created. The efficiency of Knowledge Based MDA method was validated by creating real life application for mobile devices. During the empirical research it was established that by using developed method software requirements quality is improved and comprehensive documentation is created (due to Enterprise Model based validation), occurrence of logical gaps between software development stakeholders is reduced, time consumption needed for creation of application for multiplatform systems is reduced (due to automated code generation and shorter testing stage).
Šiuolaikiniai IS inžinerijos metodai yra nuolat vystomi ir tobulinami, tačiau iš esmės jie yra grindžiami empiriniais procesais. Empiriškai išgautų žinių kokybė gali būti nepakankama sėkmingam projekto įgyvendinimui, nes netikslus vartotojo reikalavimų specifikavimas neigiamai įtakoja visus programinės įrangos kūrimo etapus, o tai didina projekto įgyvendinimo riziką. Disertacinis darbas skirtas sukurti IS inžinerijos metodą, kuris įgalintų empiriniais būdais surinktas dalykinės srities žinias patikrinti formalių kriterijų atžvilgiu. Metodui sukurti buvo apjungti žiniomis grindžiamos ir modeliais grindžiamos IS inžinerijos principai. Šiuo tikslu klasikinis MDA procesas buvo papildytas pagrindiniu žiniomis grindžiamos IS inžinerijos komponentu – veiklos modeliu. Darbo metu buvo sukurtas žiniomis grindžiamo MDA metodo dalykinės programos prototipas, kuris iš dalies automatizuoja siūlomo metodo procesą. Žiniomis grindžiamo MDA metodo efektyvumas buvo patikrintas jį taikant eksperimentinio tyrimo atlikimui, kurio metu buvo sukurta pašto siuntų stebėjimo programėlė. Tyrimo metu nustatyta, kad tikslinga taikyti žiniomis grindžiamą MDA metodą PĮ kūrime nes: 1) detaliau dokumentuojami vartotojo reikalavimai (tikrinami formalių kriterijų atžvilgiu); 2) sumažinama loginių trūkių atsiradimo galimybė (tarp programinės įrangos kūrimo dalyvių); 3) daugiaplatforminiuose sprendimuose sumažinamos projekto įgyvendinimo laiko sąnaudos (dėka automatinio kodo generavimo iš patikrintų modelių).
