Abstract:

In this work, the quality of information in the Internet and intranet will be dealt with. What characterises information of quality cannot be decided ones and for all, as it always will be in relation to the user's needs. The factors, however, that can be thought of when evaluating information can be outlined. These factors will be discussed and compared to the methods that are used by web editors to secure quality of the information in the intranet.

The methods used to investigate the paper's thesis, are the study of literature and three interviews are conducted. The study of literature is meant to reveal the aspects that can be considered when evaluating information published via the Internet and intranet. The interviews are conducted to see how web editors secure that the information in the intranet is of high quality.

The study has revealed that the following aspects can be considered when evaluating information in the Internet and intranet. These aspects are the purpose of the information; the information's authority; the accuracy, maintenance, and currency of the information and last, the accessibility and presentation of the information.

Abstract:
This thesis presents the results of research into a universal theory for quality techniques. The unique contribution that is made is twofold: • A new quality metric is proposed; • An integrating perspective to quality engineering is introduced through the application of information theory. The quality metric is designed as an information distance, measuring the difference between two probability density functions. The two distributions are the actual outcome of a running process and the expected outcome, i.e. the target distribution. The target distribution makes it possible to integrate the quality losses into the metric. The metric may be adapted to the state of knowledge of the process studied. The new quality metric is applicable to any process, be it a product processor an administration process. The information distance metric makes the analysis procedures uniform for all types of quality characteristics. A function based process documentation makes information theory generally applicable to quality engineering. The function description makes it possible to visualize poor quality as a surplus of information. All quality techniques aim at minimizing the information content in the system. Quality engineering in general may be expressed as an activity to stop surplus information flow reaching the process result. There is a natural focus on noise, i.e. influencing factors that are out of control of the user, affecting the systems. This focus is in robust design developed through a process performance perspective rather than an experimental design perspective. An effort addressing a product process subject to improvement has to be discriminated from an effort addressing the efficiency of the experimentation process used to study the product process. The present work is of pioneering character. Thus it opens a new area of research. Areas of further research are indicated.

Abstract:
There has been much advancement in the field of data and information quality (DIQ) since two decades ago. However, despite a large number of the theoretical and empirical studies in this field, there is a lack of understanding about the mechanisms and dynamics of forming, adjusting and changing organisational users’ (information consumers) assumptions and expectations based on which they perceive the quality of information required for making decision in order to perform a task within an organisational environment. Although it is already known that information consumers perceive the quality of information according to the requirements of the organisational task and the context of use, how the task requirements affect information consumers’ expectations of information quality has been a black-box in the body of literature. The main objective of this research is to contribute to the literature of DIQ by exploring the role of the setting of a task within an organisational context in the formation, development and change of information consumers’ underlying expectations of information quality. Information consumers’ assumptions and expectations are called information quality (IQ) frames by this research. Moreover, this research examines the role of IT artefacts, which are used to support performing the task, in these dynamics. As an organisational task is usually performed by a group, the role of the task group of which information consumers are members is investigated by this research. Having adopted a multi-case study design, this thesis has targeted seven different task groups in seven different organisations from multiple industries. This in-depth qualitative research also employs interviews as the main source of data and documents as the secondary source of data. The collected data and empirical evidence is analysed using the thematic analysis and pattern coding. This study’s theoretical contributions to the body of literature are as follows. Firstly, the findings indicate that information consumers should not be simply categorised into domain-specific experts or novices for understanding the mechanisms that affect their IQ frames. Regarding the domain of the task, an information consumer might have domain-related experience that differentiates him from both an expert and a novice. Moreover, this study found that the organisational-specific experience plays a significant role in these dynamics. Secondly, four different settings of a task within an organisational context have been recognised and the insights have been provided into the likely impact of each setting on IQ frames. The findings show that the setting of a task that affects IQ frames is enforced by the interplay between the degree of situatedness of the task and the degree of its explicitness. Thirdly, this research contends that the role of other members of a task group contributes directly to the setting of a task rather than directly influencing their colleague’s IQ frames. Fourthly, this thesis confirms that the organisational resource limitations and the time pressure, which were already mentioned in the literature, affect how information consumers perceive the quality of information but the empirical evidence reveals that other types of pressure such as the pressure of a competitive market has a similar role, therefore, it is argued that in general the organisational pressure impacts the way information consumers perceive information quality. However, this thesis argues that this influence is mediated by the setting of a task. In other words, the organisational pressure can increase the degree of situatedness of a task within an organisational context. Finally, the findings of this study indicate that information consumers’ interpretation of how an IT artefact enables a task within an organisational context is the key mechanism through which the IT artefact can participate in forming, adjusting or changing their IQ frames. The interpreted type of an IT artefact, its interpreted capabilities, the organisational intervention and the IT support by IT technicians of an organisations are the main four factors that govern the influence of the IT artefact on information consumers’ IQ frames. In addition, the computing environment in which the IT artefact operates in, information consumers’ level of IT knowledge and prior experience of using the IT artefact can be involved indirectly in these dynamics. The theoretical contributions of this research have led to the development of a framework for IQ frames and the underlying dynamics have been explained in detail. In addition to the theoretical contributions, this study has a number of practical implications for organisations and management regarding the importance of the organisational settings in how information quality is judged by organisational users (information consumers).

Abstract:
The explosive growth of the World-Wide-Web and the emergence of ecommerce are the major two factors that have led to the development of recommender systems (Resnick and Varian, 1997). The main task of recommender systems is to learn from users and recommend items (e.g. information, products or books) that match the users’ personal preferences. Recommender systems have been an active research area for more than a decade. Many different techniques and systems with distinct strengths have been developed to generate better quality recommendations. One of the main factors that affect recommenders’ recommendation quality is the amount of information resources that are available to the recommenders. The main feature of the recommender systems is their ability to make personalised recommendations for different individuals. However, for many ecommerce sites, it is difficult for them to obtain sufficient knowledge about their users. Hence, the recommendations they provided to their users are often poor and not personalised. This information insufficiency problem is commonly referred to as the cold-start problem. Most existing research on recommender systems focus on developing techniques to better utilise the available information resources to achieve better recommendation quality. However, while the amount of available data and information remains insufficient, these techniques can only provide limited improvements to the overall recommendation quality. In this thesis, a novel and intuitive approach towards improving recommendation quality and alleviating the cold-start problem is attempted. This approach is enriching the information resources. It can be easily observed that when there is sufficient information and knowledge base to support recommendation making, even the simplest recommender systems can outperform the sophisticated ones with limited information resources. Two possible strategies are suggested in this thesis to achieve the proposed information enrichment for recommenders: • The first strategy suggests that information resources can be enriched by considering other information or data facets. Specifically, a taxonomy-based recommender, Hybrid Taxonomy Recommender (HTR), is presented in this thesis. HTR exploits the relationship between users’ taxonomic preferences and item preferences from the combination of the widely available product taxonomic information and the existing user rating data, and it then utilises this taxonomic preference to item preference relation to generate high quality recommendations. • The second strategy suggests that information resources can be enriched simply by obtaining information resources from other parties. In this thesis, a distributed recommender framework, Ecommerce-oriented Distributed Recommender System (EDRS), is proposed. The proposed EDRS allows multiple recommenders from different parties (i.e. organisations or ecommerce sites) to share recommendations and information resources with each other in order to improve their recommendation quality. Based on the results obtained from the experiments conducted in this thesis, the proposed systems and techniques have achieved great improvement in both making quality recommendations and alleviating the cold-start problem.

Abstract:

Telecommunication systems are under constant development. Currently 3GPP is working on an evolution of the 3G-standard, under the name 3G Long Term Evolution (LTE). Some of the goals are higher throughput and higher peak bit rates. A crucial part to achieve the higher performance is channel dependent scheduling (CDS). CDS is to assign users when they have favorable channel conditions. Channel dependent scheduling demands accurate and timely channel quality reports. These channel quality indication (CQI) reports can possibly take up a large part of the allocated uplink. This thesis report focuses on the potential gains from channel dependent scheduling in contrast to the loss in uplink to reporting overhead.

System simulations show that the gain from channel dependent scheduling is substantial but highly cell layout dependent. The gain with frequency and time CDS, compered to CDS in time domain only, is also large, around 20\%. With a full uplink it can still be a considerable gain in downlink performance if a large overhead is used for channel quality reports. This gives a loss in uplink performance, and if the uplink gets to limited it will severely affect both uplink and downlink performance negatively.

How to schedule and transmit CQI-reports is also under consideration. A suggested technique is to transmit the CQI reports together with uplink data. With a web traffic model simulations show that a high uplink load is required to get the reports often enough. The overhead also gets unnecessary large, if the report-size only depends on the allocated capacity.

Thesis submitted in fulfilment of the requirements for the degree Master of Technology: Information Technology In the Faculty of Informatics and Design at the Cape Peninsula University of Technology
Dealing with information quality issues remains a serious concern for organisations. With the fact that modern organisations generate much higher volumes of information than they did in the past, with more variety and at a higher velocity, this concern is only expected to increase. Information quality is a complex topic and there is no single view shared by stakeholders on the quality of information within an organisation’s value chain and information quality issues experienced by stakeholders are also different. In this study, the topic of information quality is addressed through the following research questions: How do information stakeholders view the quality of information throughout the information value chain of a retail organisation? What kind of information quality issues do business stakeholders experience throughout the information value chain of a retail organisation? And how are stakeholder decisions affected by information quality when producing or consuming information at the different touch points of the information value chain? An interpretive research approach was chosen for this study to explore this complex topic. The research was conducted in two phases. A literature review in which different concepts related to information quality were investigated was the first phase. In the second phase, a specific business case was investigated before findings from the two phases were analysed and discussed In response to the main research questions, the findings of the research indicated that information quality is complex and there is no single view shared by all stakeholders involved in an information value chain.

Abstract:

Quality has always been an elusive concept in information system design, even more so when dealing with the online-sphere. The purpose of this thesis is to investigate and dissect the concept of quality and present a practical way to apply it to the design process. To do this, a quality-driven design model has been developed, focused around four crucial aspects of overall quality: accessibility, usability, navigation and interactivity. By utilizing simple and practical techniques and measuring their success in achieving quality, this study attempts to prove that quality can be harnessed as a hands-on resource, guaranteed in any design project involving a Web-Based Information System, merely by applying this model.


Kvalitet har alltid varit ett begrepp svårt att fånga och tillämpa, speciellt när området Internet kommer in i bilden. Den här C-uppsatsen har således som syfte att undersöka och bryta ned kvalitetskonceptet samt presentera ett praktiskt tillvägagångsätt som kan utnyttjas under design processen. För att göra detta så har vi utvecklat en kvalitetsdriven designmodell, fokuserad runt fyra kvalitetsaspekter: tillgänglighet, användbarhet, navigation och interaktion. Genom att utnyttja praktiska och enkla tekniker och genom att mäta deras effektivitet i att utveckla kvalitet, så försöker den här studien att bevisa att kvalitet kan användas som en praktisk resurs. Kvalitet kan garanteras i alla designprojekt som involverar ett web-baserat informationssystem, genom användning av denna modell.

Abstract:
E-learning systems provide a promising solution as an information exchanging channel. Improved technology could mean faster and easier access to information but does not necessarily ensure the quality of this information. Therefore it is essential to develop valid and reliable methods of quality measurement and carry out careful information quality evaluations. Information quality frameworks are developed to measure the quality of information systems, generally from the designers¿ viewpoint. The recent proliferation of e-services, and e-learning particularly, raises the need for a new quality framework in the context of e-learning systems. The main contribution of this thesis is to propose a new information quality framework, with 14 information quality attributes grouped in three quality dimensions: intrinsic, contextual representation and accessibility. We report results based on original questionnaire data and factor analysis. Moreover, we validate the proposed framework using an empirical approach. We report our validation results on the basis of data collected from an original questionnaire and structural equation modeling (SEM) analysis, confirmatory factor analysis (CFA) in particular. However, it is difficult to measure information quality in an e-learning context because the concept of information quality is complex and it is expected that the measurements will be multidimensional in nature. Reliable measures need to be obtained in a systematic way, whilst considering the purpose of the measurement. Therefore, we start by adopting a Goal Question Metrics (GQM) approach to develop a set of quality metrics for the identified quality attributes within the proposed framework. We then define an assessment model and measurement scheme, based on a multi element analysis technique. The obtained results can be considered to be promising and positive, and revealed that the framework and assessment scheme could give good predictions for information quality within e-learning context. This research generates novel contributions as it proposes a solution to the problems raised from the absence of consensus regarding evaluation standards and methods for measuring information quality within an e-learning context. Also, it anticipates the feasibility of taking advantage of web mining techniques to automate the retrieval process of the information required for quality measurement. This assessment model is useful to e-learning systems designers, providers and users as it gives a comprehensive indication of the quality of information in such systems, and also facilitates the evaluation, allows comparisons and analysis of information quality.

Abstract:
In this study, value of quality information and the eects of centralization are investigated for a reverse supply chain consisting of a remanufacturer and a collector. Used products are collected and inspected to classify them into quality groups, then they are remanufactured to meet the demand of remanufactured products. The supply of collected products and demand of remanufactured products are both price-sensitive. The uncertain quality of the collected products is revealed by an inspection process. Two quality classes are considered, and the cost of remanufacturing depends on the quality class. The main decisions are on acquisition fee for the returns, the selling price for remanufactured products, and the transfer prices of inspected products between the collector and the remanufacturer. For this environment, centralized and decentralized settings are considered and dierent models that dier in availability of quality information when the pricing decisions are made are built. We explore the value of advance quality information and eects of centralization on the optimal prices and profits via a computational study.

Abstract:
This research contributes to provide a better understanding of the nature of accounting information reliability by measuring the relation between the informativeness of earnings and corporate governance based on the Chinese context with its unique political, social, cultural and economic environment and large sample size. In particular, mainland China has a distinct two-tier board structure comprising a supervisor board including employee representatives and board of directors of whom at least one third are independent directors. The objective of this thesis is to investigate accounting information reliability and corporate governance by addressing three predominant empirical research questions in three studies. The first study examines the impact of board composition and independence on earnings management in mainland China through investigating whether independent directors and supervisors are effective at restraining earnings management. To fully capture the earnings attributes, the second study investigates the quality of reported earnings in China from the perspective of both accounting-based (including accrual quality, persistence, predictability and smoothness) and market-based earnings attributes (including value relevance, timeliness, and conservatism and earnings response coefficient). A two-way test has been conducted to compare the difference in earnings quality between State-Owned and Non-State-Owned enterprises. According to financial distress theory, the incentives for Non-SOEs to manipulate earnings are stronger than in SOEs, since SOEs have the advantage to receive financial subsidies from government while Non-SOEs face more financing constraints. The agency theory, however, argues that state ownership in SOEs creates incentives and regulatory backing for self-serving purposes, thus motivating SOEs to manipulate accounting numbers. The political cost hypothesis complements the agency theory and illustrates that SOEs’ managers would manipulate accounting numbers in response to government intervention (report conservatively to disguise the profits or report aggressively to meet specific thresholds). In addition, it tests whether analysts' forecasts are more accurate than forecasts based on time-series predicted statistics with random walk. Finally, the third empirical study detects whether managers intend to manipulate earnings via discretionary accruals in order to just meet or beat consensus analyst forecasts on the basis of earnings surprise (analyst forecast error). The key findings of the first study in this thesis suggest that the distinct Chinese two-tier board structure comprising independent directors and supervisory directors fails to mitigate earnings management. The second study documents that Chinese SOEs overall exhibit a lower earnings quality than Non-SOEs, supporting the agency theory. Government ownership might create incentives and regulatory backing for self-serving purposes that negatively influence the listed firms’ financial reporting. Moreover, SOEs manipulate downwards the earnings much more than Non-SOEs, manifesting the government generally expropriate the benefits of SOEs, according to the political cost hypothesis. One interesting finding in second study is that predicted earnings based on the time-series statistical model with drift are more accurate than the consensus analyst forecast. This result conflicts with findings from developed country studies, indicating the malfunction of financial analysts in mainland China. In the third empirical study, the findings suggest an optimistic bias in analysts' forecasts exists in Chinese listed companies but fail to provide any evidence supporting that discretionary accrual measures are positively associated with just meeting or beating the analysts’ forecast benchmark. It challenges the ‘benchmark beating’ incentive in most prior literature based on western developed countries, such as the US and the UK.

Abstract:
In less than a generation, the World Wide Web has grown from a relatively small cyber play-ground of academic "geeks" into an 11.5 billion-page collection of heterogeneous, inter-connected, network of information and collective knowledge. As an information environment the World Wide Web is informatically representative of all that is good and bad about the human need to both absorb and transmit knowledge. The 'open' nature of the Web makes instantly available to anyone who can "log-on", a boundless digital library of information, the quality of which cannot be enforced before, during, or even after its publication. Scrutiny of Information Quality (IQ), is therefore left up to those publishers conscientious enough to care about the quality of the information they produce and the users who choose to employ the Web as an information retrieval tool. The following thesis is a qualitative investigation of how the users of information make value-judgments about the information they encounter and retrieve from the Web. Specifically, it examines perceptions of IQ from the perspective of eighty "academic" high-end users, who regularly engage the Web and its search engines to search for and retrieve high-quality information related to their research, teaching and learning. The investigation has adopted an inductive approach in the qualitative analysis of quantitative ( 10,080 separate pieces of user-data) data in the context of such established frameworks as Davis' ( 1986, I 989) Technology Acceptance Model (TAM), and Wang & Strong's ( 1996) contextual IQ framework that conceptualised dimensions of quality into four IQ categories, namely: intrinsic; representational; contextual; and accessibility IQ. Through the detailed analysis of the driving theory behind these, and other associated models of: (I) user IT acceptance; (2) Information Seeking Behaviour (ISB}; and (3) multi–dimensional characteristics of IQ; the researcher has sought to find synergies and develop an innovative framework by which to explore the impact of users' attitudes, expectations and perceptions of IQ on their Web information retrieval behaviours. The findings associated with the thesis are consistent with the proposal of a new Ongoing Technology Acceptance Model (OTAM), which facilitates the measurement of users perception of the predictability of their technology interactions, and has the capacity to more accurately investigate user individual differences. Importantly, the OTAM allows the constructs of the original TAM, along with a new construct “Perception of Interaction" (Pol) to be used to investigate users ongoing use of technologies. Findings associated with user perceptions of information quality are also explored and discussed in relation to a proposed life-cycle model of IQ.

Abstract:

Use qualities are sought after in interaction design and increasingly reachable given the new developments in tangible, ubiquitous and embodied interactions. But are they really obtainable regardless of what approach one chooses. This thesis explores how use qualities can be reached by Organic Interaction Design and in doing so it also provides a primer for what this concept entails: A concept which demands a high level of intuitivity in the designs of new media and new interaction trajectories. It is implemented here in a case of an interactive table complete with tangible interactions. This thesis provides examples of how use qualities such as immersion, playability and even vulnerability are reached not via e.g. system transparency but rather via a mimicry of the tacit cues of biological systems occurring in the natural world. The interaction design need be thoughtful and holistic for such endeavors.

Full text
Abstract:

Records are a subset of information and recordkeeping requirements demand that a record is managed with maintained authenticity and reliability, i.e. with high quality. Records are evidence of transactions and are used and managed in daily work processes. Records may be preserved for anything from milliseconds to eternity. With computer based information systems the electronic record was born: a record that is born digital. With electronic records problems regarding maintenance of authenticity and reliability have been identified. Electronic records are no longer physical entities as traditional records were. An electronic record is a logical entity that can be spread over different locations in a computer based information system. In this research the aim is to improve the possibility of reaching high quality in recordkeeping systems, i.e. to maintain reliability and authenticity of electronic records, which is necessary if electronic records are to be usable as evidence of transactions. Based on case studies and literature studies, a recordkeeping quality model is presented: a predictive model for attaining quality in recordkeeping. The recordkeeping quality model consists of four major concepts which are interrelated with each other: Electronic records, Records use, Electronic record quality, and Multidimensional perspective. The model is proposed for use when designing and developing computer based information systems which are required to be recordkeeping, systems which manage electronic records. In this research two results beside the recordkeeping quality model are emphasized. The first is that quality in recordkeeping must be seen in a multidimensional perspective, and the second is that recordkeeping systems are information systems with a partially unknown purpose.

Abstract:
Information management has been identified as an essential requirement for the structural engineering sector in a highly competitive AEC marketplace. In the field of structural engineering, information management represents a challenging discipline due to several factors such as a lack of clarity in the adoption of novel technologies, the multitude of different and ambiguous standards available, and the lack of human resources readiness. This research demonstrates that information quality plays a very important role in structural engineering information management as poor quality of structural engineering design information leads to reworks and failures in tendering and construction of projects. 80% to 90% of failures in buildings, bridges and other structures result from errors in design. Novel technologies and workflows have to be adopted by structural engineering organisations, which also need to improve the readiness of their human resources to enhance information management during conceptual, detailed and technical design phases. It is but natural for project teams in structural engineering organisations to expect proper quality of information during the bidding procedure, while providing documents for constructors and also while reporting to clients to make assured accurate decisions. A review of relevant literature revealed that Building Information Modelling has a contributory role in addressing the challenges of information management in various disciplines of the AEC industry. However, to ensure effective contribution of BIM on structural engineering information management, a clear determination is needed to improve information quality. Therefore, the aim of this research is to develop a conceptual framework for the adoption of BIM to enhance the quality of information in structural engineering organisations of the UK. In this research, an interpretivism philosophical position has been adopted that understands the real world and solves related problems over interpretations provided by participants. This research triangulated case study and survey approaches to the investigation of the research objectives in order to enrich confidence in presenting findings. A qualitative and quantitative approaches (or mixed-method approach) were used to thoroughly explore factors that have a key role in developing a framework for improving information within the AEC industry. Data collection involved the use of semi-structured interviews followed by scale questionnaires that were given to design experts in the UK. The qualitative data comprised of 12 interviews with experts performing the role of structural engineers, BIM managers and design managers in two structural engineering departments of two different large multidisciplinary organisations in the UK. In the context of quantitative data collection, 125 respondents replied to the researcher within two months. Finally, both qualitative and quantitative data were analysed and conceptual framework was developed and validated. This research points out that at present the UK structural industry is dissatisfied with the quality of structural engineering information and holds the opinion that catastrophic failure in the construction process may result from inadequacies in the information management system. From this research, it is evident that the key dimensions for structural engineering information quality can be explained by information accuracy, information accessibility, and information interoperability and information security. This research examined the key criteria that need to be considered while adopting BIM technological tools, workflows and human resources in the context of structural engineering sector. An initial conceptual framework developed by reviewing the existing literature illustrated the potential power of BIM to contribute to the level of information quality management in structural information management. Primary data collected in this research explored the role of crucial factors of BIM implementation in promoting the key dimensions of information quality management. This research contributes to knowledge by developing a conceptual framework which can be implemented in the ACE industry to improve upon information quality by assisting decision makers associated with structural engineering information management to adopt appropriate technological and workflow protocols, and also to ensure organisational human resource readiness in the contest of BIM. Avenues for further research in this area of information quality management in the structural engineering sector were also recommended by this study.

Abstract:
Abstract Since the collapse of the Soviet Union Russia has undergone a number of reforms towards developing market economy. Accounting has encountered dramatic changes over the last two decades. Despite attractive investment opportunities in Russia, investors are often faced with uncertainty, which makes it very important to explore the quality of accounting information published in Russia. The purpose of this thesis is to investigate the quality of published accounting information in Russia. The thesis consists of four essays, each of them addressing the question of the quality of accounting information published in Russia by incorporating the specific Russian institutional environment. Special attention is paid to the role of International Financial Accounting Standards (IFRS) and foreign investors. The quality of published accounting information is conceptualized by such accounting constructs as conservatism, earnings management and value relevance. This first essay investigates the earnings quality of both listed and non-listed Russian firms and explores whether foreign ownership affects the quality of earnings published by non-listed Russian firms. The second essay examines whether emphasis on international investors is associated with the adoption of or intention to adopt IFRS in Russian firms. The third essay addresses the question of IFRS and Russian Accounting Standards (RAS) accounting quality by using the methodology proposed by Barth et al. (2008) and by value relevance constructs of accounting quality. The fourth essay investigates the value relevance of firms’ integral environmental impact, i.e. a proxy for environmental performance, following the stream of non-financial information value relevance in accounting research. This thesis provides evidence that the quality of published accounting information published in Russia depends on many factors, the most influential of these being listing on the stock exchange, IFRS and foreign investors. The results of the thesis demonstrate that the institutional characteristics of the country shape accounting numbers and influence the incentives of those preparing financial statements. The findings of the thesis include information valuable for regulators and investors.

Abstract:
The motivation for this research is a concern with the high rate of information system failures reported in the academic literature and in practitioner publications. It is proposed that the adoption of the customer-centred ideals and methods of quality management in information system development will increase the likelihood of the delivery of successful information systems. The approach taken in the research is to work with the ideas of multiple perspectives - organizational effectiveness, work-life quality, and technical artefact quality - and multiple stakeholders. The research approach is to use action research. The fieldwork comprises three phases. The first phase involved interviewing system developers and the second phase consisted of two case studies of implemented information systems. This preliminary analysis, together with a theoretical investigation of the foundations of quality, was used to inform the development of a quality approach to information system development. The information system development methodology (ISDM) is based upon Multiview, a multiple perspective approach to information system development, and the total quality management method used is quality function deployment. The resultant hybrid methodology is known as ISDM/Q. The ISDM/Q is tested using action research on a live system development project concerned with the development of a wind tunnel control and data collection system. Extensive organizational analysis was conducted to place this software development within a wider organizational context, involving quality requirements workshops and quality planning. The outcomes of the research are assessed in terms of the learning recorded with respect to the framework of ideas, the methodology (ISDM/Q) and the domain in which the action research took place. The field work showed that there were benefits to using a quality metaphor in information system development but that this would require a significant change in the culture and style of information system development organizations. A practical contribution of the research is the development of quality function deployment for information system development.

Abstract:
Many companies are increasing their competitiveness through quality improvement. However, a widely held view among quality practitioners is that companies simply do not know the true total cost of quality, which are mostly hidden among the general overhead of the business. This problem is often attributed to an inappropriate costing system. Thus, any system that assisted companies in identifying and properly quantifying these costs will be valuable. This research, therefore, was aimed at developing a Quality Cost Information System for manufacturing industry, and to show that such a system could provide a basis for analysing quality costs and developing and evaluating the quality improvement process. A literature review of the quality literature highlighted that the major problems that hindered potential users from implementing an effective and efficient Quality Cost system were: current quality cost measurement systems were limited by their inability to trace quality costs to their source; quality was manageable only if it could be measured; quality cost did not easily fit into the traditional cost accounting structure; traditional accounting systems were unlikely to change radically to accommodate proper quality costing. This literature review was complemented by an industrial survey aimed at identifying knowledge of quality costing and current practices in manufacturing industry. The findings of the literature review and industrial survey formed the basis for the remainder of the study. As part of an integrated solution, three approaches have been proposed and detailed: 1) A graphical model of quality costing in the form of a visual tool to facilitate the introduction and communication of a quality costing information system within the organisation. 2) A proposed integration of Activity Based Costing tools with the theory of quality costing to provide a system that can deliver valuable information. 3) A Software tool for the design of Quality Costing Information Systems. The thesis concludes with the major findings and issues raised from the research undertaken. This is followed by recommendations for the successful pursuit of the beneficial implementation of the proposed quality costing system and tools along with several suggestions for further work and future research potential.

Abstract:
The Patient Protection and Affordable Care Act (PPACA) is slowly transforming the U.S. Health Care System from a fee-for-service structure, which reimburses providers based on the quantity of patient encounters, to a new structure that emphasizes the value of care. Since value can be interpreted differently among various stakeholders, quality measures have been established by government and nonprofit sources. These quality measures serve as agreed-upon criteria by which to measure the achievement of value in health care. While these measures help to improve the quality of health care, they can also be burdensome to physicians and health care organizations. Implementation of quality measurement programs requires the involvement of highly intelligent people who think about what to measure, what to focus on, and how to accomplish outcomes. Thus, the process of selecting measures and compiling recommendations (reports) can be time consuming, complicated, and expensive. Applying SELP coursework fundamentals, key process activities outlined by INCOSE, and the DoD Architectural Framework, a quality measure information system was developed. The primary business objective (top level requirement) of the project was to reduce the cost and improve the quality of the measure selection and report generation processes. First, fundamental systems engineering principles were applied to understand the problem, conduct a lean analysis, identify stakeholders' needs, and derive a set of requirements to meet the primary business objective. Subsequently, five alternative solutions were evaluated to identify a preferred solution that could best meet the primary business objective while minimizing risk. The DoD Architectural Framework and course material from Integration of Hybrid Hardware and Software Systems (SELP 560) was then applied to develop, represent, and understand the information system architecture. Finally, leveraging Management Information Systems Coursework (MBAA 609), a system prototype was created utilizing Microsoft Access. The system prototype demonstrated a capability to reduce the cost and improve the quality of the health care quality measure selection and report generation processes. Utilizing pre-selected associations between various quality measures and categories of care, comprehensive quality measure reports can be generated in a matter of seconds for many categories of medical care. These comprehensive reports serve to educate users about various quality measures and to aid administrators in the development of comprehensive quality measurement programs. In one particular example, health care organizations will utilize the generated quality measure reports for the purpose of redesigning compensation and incentive pay for physicians and health care executives. In this particular example, estimates show that the system prototype is expected to reduce the labor associated with measure research and selection by approximately 49%, resulting in thousands of dollars of estimated savings. Additionally, the system will automate complicated measure search processes, which will increase the quality and consistency of the reported data.

Abstract:
Data quality has been an area of increasing interest for researchers in recent years due to the rapid emergence of 'big data' processes and applications. In this work, the data quality problem is viewed from the standpoint of synthetic information. Based on the structure and complexity of synthetic data, a need to have a data quality framework specific to it was realized. This thesis presents this framework along with implementation details and results of a large synthetic dataset to which the developed testing framework is applied. A formal conceptual framework was designed for assessing data quality of synthetic information. This framework involves developing analytical methods and software for assessing data quality for synthetic information. It includes dimensions of data quality that check the inherent properties of the data as well as evaluate it in the context of its use. The framework developed here is a software framework which is designed considering software design techniques like scalability, generality, integrability and modularity. A data abstraction layer has been introduced between the synthetic data and the tests. This abstraction layer has multiple benefits over direct access of the data by the tests. It decouples the tests from the data so that the details of storage and implementation are kept hidden from the user. We have implemented data quality measures for several quality dimensions: accuracy and precision, reliability, completeness, consistency, and validity. The particular tests and quality measures implemented span a range from low-level syntactic checks to high-level semantic quality measures. In each case, in addition to the results of the quality measure itself, we also present results on the computational performance (scalability) of the measure.

Abstract:
Fatal occupational injury is a construction and management problem in the United States. Fatality rates among specialty trade contractors made up the largest percent of fatalities in construction at 62% per year. The purpose of this nonexperimental study was to examine the relationship between the quality of information in construction safety plans and construction safety among specialty trade contractors. The theoretical foundations for the study were Petersen'€™s accident/incident theory and work systems theory. The key research question was to examine the relationship between information quality and construction safety among specialty trade contractors. A survey with closed-ended questions was used to collect primary data from a self-selection sample of 134 specialty trade contractors in the United States. Spearman rank correlation coefficient (rs) was used to measure the strength of the relationship between information quality and construction safety. Results indicated that the quality of information in construction safety plans (measured by the relevance, accuracy, timeliness, and completeness of information) did not have any statistically significant relationships with construction safety among U.S. specialty trade contractors. Further research is needed to understand if the variables used in this study are relevant predictors for construction safety. This study connects with positive social change by bringing into focus quality information systems research required to improve safety among U.S. specialty trade contractors and provide safety professionals a direction for continuous safety improvement in the U.S. construction industry, thus benefitting construction stake holders.

Záměrem předložené disertační práce je porozumět tomu, jak investoři v konkrétním společenském kontextu vnímají význam kvality informačních systémů. Ze studia literatury zabývající se přístupy a rámci hodnocení kvality informačních systémů vyplývá, že tato kvalita je obecně hodnocena z hlediska striktního přístupu. V této práci je ukázáno, že kvalitu informačního systému lze smysluplně pochopit použitím interpretačního paradigmatu a že kvalita informačního systému je definována společensky a ovlivňována kontextem tohoto systému. Studie byla zahájena průzkumem dvaceti libyjských organizací. Podrobnější data byla získána z případové studie dvou vybraných libyjských organizací působících ve veřejném sektoru. Při empirické analýze nashromážděných dat bylo využito rámce mnohočetné perspektivy, který zahrnuje hlediska teorie strukturalizace, pojem mnohočetných perspektiv a metodologii měkkých systémů. V práci se dospělo ke zjištění, že: a) kvalita informačních systémů je pojata šíře, než je tomu u tradiční definice kvality, b) mnohočetné perspektivy kvality informačních systémů jsou ovlivněny opakovanou interakcí mezi investorem a institucionálními vlastnostmi kontextu informačního systému a že c) rozdílné hodnoty v kulturním prostředí a vnějším kontextu ovlivňují rozsah působnosti investora a interakce v kontextu informačního systému. Ze závěru práce vyplývá, že společenská skladba mnohočetných perspektiv kvality informačního systému je ovlivněna strukturalizačními procesy mezi investory a vlastnostmi v kontextu informačního systému.

Abstract:
Cette thèse est consacrée à la question de l’information fournie aux consommateurs par les marchés ou les Organisations Non Gouvernementales (ONG) sur la qualité environnementale des produits. La problématique s’inscrit dans un contexte où d’une part, les consommateurs prennent davantage en compte cette dimension dans leur choix de consommation et d’autre part, les entreprises affichent de plus en plus une responsabilité sociale ou environnementale dont la réalité est souvent contestée. La remise en question progressive de la crédibilité de la certification verte mène à notre premier travail qui analyse le rôle du prix comme un moyen de communication alternatif. Le but est d'examiner comment une firme verte en concurrence avec une firme brune peut résoudre le problème d'asymétrie de l'information. Pour cela, nous développons un modèle de duopole verticalement différencié dans lequel les firmes peuvent signaler leur qualité à travers les prix. Afin de représenter une concurrence accrue sur le segment de basse qualité, nous faisons l'hypothèse que le bien brun est tarifé au coût marginal. Le résultat est extrême : il n'existe aucune situation où la firme verte peut résoudre le problème d'asymétrie de l'information. Le second travail prend en compte le rôle des ONG dans le processus informatif concernant le type des firmes. L'étude de l'interaction entre, la stratégie de signal en prix de la firme et, l'information donnée par l'ONG mène à des résultats prometteurs concernant la diffusion de l'information sur la qualité environnementale. Lorsque les consommateurs ne peuvent pas vérifier l'engagement environnemental, les firmes peuvent être défiantes à opérer des changements dans leur processus de production pour prendre en compte ces problématiques. Nous montrons comment la surveillance imparfaite peut atténuer ce problème d'aléa moral. De ce fait, nous complexifions le modèle standard de signal en prix en permettant aux consommateurs d'utiliser les résultats d'enquête sous diverses formes comme complément d'information. Avant d'envoyer un signal aux consommateurs, les firmes décident ou non de s'engager à résoudre des problèmes environnementaux. Sans le contrôle de l'ONG, les firmes ne s'engagent pas dans la résolution de ces problèmes car il est impossible pour elles d'envoyer un signal crédible via le prix. Avec le contrôle de l'ONG, il existe des équilibres dans lesquels les firmes investissent pour atténuer les problèmes environnementaux et arrivent à signaler leur choix via le prix. Dans un troisième travail nous nous intéressons à la nature de l’information émise par l’ONG. Soit une révélation accréditant la firme, soit une preuve discréditant la firme. Ces types de preuves vont de pair avec les stratégies de "championing" et de "shaming". Dans cet esprit, nous rendons endogène le choix du signal de l'ONG qui interagit avec la stratégie de signal de la firme. Nous analysons l'effet de ces deux différentes stratégies sur l'équilibre en signal des firmes et la stratégie d'information optimale de l'ONG. La technologie ici est exogène, et le consommateur est parfaitement bayésien par rapport aux deux signaux qu'il reçoit. Nous trouvons que la stratégie de "shaming" réduit le coût du signal pour le bon type et peut même rétablir le prix en information complète. La stratégie de "championing" peut faire disparaître les incitations du marché à révéler la vérité. Concernant le comportement informatif de l'ONG, lorsque le marché révèle l'information, celle-ci est indifférente entre adopter une stratégie de "shaming" ou de "championing". Quand le marché cache l'information, la stratégie dépend de la différence d'efficacité dans la détection du type de la firme, ainsi que de la distribution du type des firmes sur le marché
This thesis focuses on the question of the information transmitted to consumers by the markets and Non Governmental Organizations (NGOs) on the environmental quality of products. This work takes place in a context where, on one hand, consumers' awareness increase concerning this dimension, and on the other hand, firms increasingly display a social or environmental responsibility whose reality is often contested. The first paper investigates the role of price as a possible substitute channel of communication. The purpose is to examine how a green firm competing against a brown firm can solve the asymmetric information issue. For this purpose, we develop a simple vertically differentiated duopoly model where firms can signal their quality through prices. To represent an increasing pressure of the competition on the low-quality segment, we make the hypothesis that the brown good is sold at the marginal cost. The result is extreme: there do not exist any situations where the green firm can solve the asymmetric information issue. The second paper takes into account the informative role of NGOs concerning the type of firms. We are interested in how their informational behavior impacts the signaling strategy of firms. The interaction between the price signaling strategy of the firm and the information released by the NGO yield fruitful results concerning the path of green information.When consumers cannot verify corporate social goodwill, firms may be reluctant to uphold a pledge of social goodwill. We show how imperfect monitoring can mitigate this moral hazard problem. We augment the standard model of price signaling by allowing consumers to use the results of independent monitoring as a complementary source of information. Monitoring corrects for consumers' arbitrary beliefs. Before sending a price signal to consumers, firms pledge or not to invest in social goodwill.With no monitoring, firms do not abide by their pledges of social goodwill when they fail to send a credible signal via price.With monitoring, there exist equilibria in which a firm invests in social goodwill and succeeds in signaling its choice via price.It is worth mentioning that the hard evidence displayed by NGOs can be of two different natures. In this Chapter, the types of discovered evidence go in pairs with shaming and championing strategies. In this spirit, we endogenize the signaling choice of the NGO, which interacts with the signaling strategy of a firm. We seek to analyze the effect of these two different strategies on the equilibrium of signaling of the firm and the optimal informative behavior of the NGO.The technology choice here is exogenous, and the consumer is perfectly Bayesian according to the two different signals received. Either a proof discredits the firm, or a proof accredits the firm. We find that the shaming strategy reduces the signaling cost for the high type and can even restore the perfect information outcome. The championing strategy can make incentives for the market to reveal the truth disappear. Concerning the optimal informative behavior of the NGO, if the market reveals information, the NGO is indifferent between adopting a shaming strategy and adopting a championing strategy. When the market conceals information, the strategy depends on the difference between the shaming and championing efficiency and the distribution of the firm in the market

Abstract:
The present research work is an exploratory study that aims to investigate the impact of Big Data Customer Analytics Use (BDCAUse) in customer relationship management (CRM) by providing a comprehensive overview of the main factors that can affect BDCAUse in the organizations andhow this use affects the information quality. The influence of BDCAUse could bring benefits and increase the competitive advantage for the companies. More precisely, this study analysed if customer orientation and big data analytics culture would improve the use of big data customer analytics in the organization, and if this would, in turn, enhance the quality of the information, thus the customer knowledge, get into more insights about the customer behaviour and answer the right needs of its customers. Using an online survey, respondents from different business units in different organizations and companies were invited to participate. The author received 20 responses of which 18 were considered valid. The data was analysed using the SPSS tool and SmartPLS to analyse the consistency of the measures used and to test the suggested research model.  The results show that customer orientation and big data analytics culture are key to influence the use of big data customer analytics to be able to gather information quality and improve the CRM performance in the organization. The main limitations of the research work consisted of collecting data with a relatively very small sample, although these were designed as an exploratory study to test first identified factors that could affect big data customer analytics use. A recommendation for future research would be to run the study with a larger sample size to analyse the research model and check again the reliability of the measures and the validity of the results. Keywords: Big Data Customer Analytics Use, Customer Orientation, Big Data Analytics Culture, Information Quality, Customer Relationship Management Performance
