Abstract (sommario):

Despite over a decade of study, little is really known about information systems development and the use of systems development methodologies. There has been little evaluation of methodologies in use or examination of the selection, development, adaptation or use of methodologies in practice. This paper discusses this lack of knowledge and its ramifications for research and practice.

Abstract (sommario):

Many organizations develop their information systems without the use of any information systems development methodology. However, even when organizations identify the need for the use of such methodologies, it is not always obvious which to use, or whether a blended combination might be appropriate. Further, in using either stand-alone or blended information systems development methodologies in practice, a number of difficulties are encountered. This paper discusses the use of an information systems development methodology which consisted of a blend of other methodologies in a real-world situation (a large telecommunications company) where no formal methodology had been used previously. A number of difficulties arose in practice, some of which were not anticipated. Examples are given of the types of difficulty encountered, and these fell into three broad categories: those related to the deficiencies in the design techniques and tools themselves; those related to implementing the system from the design; and those related to the particular environment.

Abstract (sommario):

Over the years, organizations have seen fit to adopt the use of agile systems development methodologies (ASDMs) because of the benefits that they offer, such as flexibility and the ability to deliver products faster, in constantly changing environments. When ASDMs are used in projects, they are made to fit or be suitable for a project‟s unique aspects, such as its size, requirements, scope and outcomes. This is known as the contingent use of ASDMs. Little is known about the contingent use of ASDMs in South African organizations. It is not known whether it is happening, its procedure and its success. It is important to know this because quality and control need to be maintained in systems produced. There is always a danger that the benefits of using a system development methodology (SDM) would be lost if ASDMs are highly adapted. This led to an investigation of three organizations in South Africa that use contingent ASDMs. With the help of semi-structured interviews, focus groups and documents, data was collected that was analysed, using the tool ATLAS.ti, and the analysis methods content and cross-case analysis. It was found that some South African organizations in the telecommunications, consulting, technological, outsourcing and agricultural sectors use ASDMs in combination with the still popular waterfall SDM. Compatibility between the SDM and the project is a factor in some organizations. Scrum was cited to be the ASDM that was used in some of the organizations interviewed due to its maturity. They make ASDMs contingent by using aspects in the methods, such as Scrum, that are useful for their unique projects. These aspects are in some cases combined with other SDMs to form hybrid methodologies. Some organizations use criteria, such as project needs, outcomes, size and complexity to make ASDMs contingent. Some organizations have measures and facilities in place to manage, monitor, control and document the process used to make ASDMs contingent. They make use of contingent ASDMs as they have experienced more success with them and they will continue to do so.

Abstract (sommario):

Information systems are getting more and more multimedia-based as well as network-based. This evolution, as well as an increased rate of change, put new demands on methods and competencies required for developing future information systems. In this work, we give an overview of the different types of information systems and methods for information systems development, especially with respect to multimedia aspects. Multimedia systems development is discussed particularly with respect to the dual processes of software engineering and content development. Possible future directions are pointed out, in which information systems development seems to become an even more multidisciplinary effort. As a result we present a list of competencies required for multimedia information systems development as well as possible research areas of interest. These research areas cover the following issues regarding the development of multimedia information systems: project management, conceptual modelling, content maintenance, requirement treatment and development approaches.

The United States Department of Defense has been plagued with failing programs that are over budget, behind schedule, and exhibit poor performance during testing. Once a program has cost, schedule, or capability issues, follow-on development efforts adopt the underlying issues only to reinforce poor performance. To address these issues that lead to firefighting, one option is to use an Agile software development process to introduce capabilities earlier in the development process for effective testing. Two System Dynamics models compare Agile with the traditional Waterfall development approach to determine: if Agile development reduces the conflict between cost, schedule, and capability constraints; if Agile development reduces firefighting; and will Agile development impact other development tasks. Based on the simulation of each model, Agile did improve the dynamics of parallel development cycles by maximizing the productivity of the entire development team. Under the same System and Software Engineering team size and development release schedule, Agile development increases the quantity of requirements introduced within a development cycle. However, Agile development emphasized less on maturing new technologies leading to considerably less innovative builds. Thesis Supervisor:

Abstract (sommario):

Systems architecting has been evolving for the last several decades. There have been significant advances in systems engineering and development technologies to directly address large, complex systems that present formidable risks and difficulties in their design, construction, deployment and evolution. These advances have focused on the earliest period of design decision-making and evaluation, referred to as the architectural level of system development. The architectural level of systems development consists of making decisions about overall design goals, requirements, structure, and development strategies. Many analysis and development innovations have resulted from this attention to the architectural level. Among these innovations are architecture modeling languages with associated tools and environments; architecture frameworks, model languages, tools; and techniques for architecture analysis, evaluation, and architecture-based reuse. Boeing has capitalized on these advancements by investing in the development of processes and tools. This paper presents a recommended system architecture approach and processes for implementing an architectural modeling framework (i.e. DODAF), language (i.e. SysML), and tool. It will provide a frame of reference within which to address implementation and adoption decisions. To these ends, this project is intended to determine the value of implementing SysML in a spacecraft development environment.

Abstract (sommario):

Research has shown that data warehouses potentially offer great investment opportunities to business. To benefit from this, business needs to invest large sums of money. Such investments are very risky, as no guarantee of the success of these ventures can be given. Object-oriented development has proved successful for developing operational systems in industry. This study researches object-oriented techniques to discover whether these techniques could be used successfully in data warehousing. A literature study focuses on the definition of an information systems development methodology and defines the components of such methodology. A further literature study on four popular object-oriented methodologies determines the commonalities of these methodologies. In conclusion, a literature study on data warehouse methodologies is done to discover the phases and techniques used in developing data warehouses. Based on the literature, a method is proposed to build a data warehouse harnessing object-oriented phases and techniques. The proposed method is applied as an interpretive experiment, followed by an evaluation of the data warehouse implemented.

Abstract (sommario):

This paper explores the relationships between jazz and the development of information systems. Similarities are drawn between music in general and information systems development methodologies and jazz is taken as a specific focus. The idea of music as an information system in its own right is outlined. As systems development methodologies move from formal approaches towards more ad hoc forms, the lessons that can be learned from jazz, such as improvisation and shared meaning, may become increasingly useful.

Abstract (sommario):

Since its inception, Systems Engineering (SE) has developed as a distinctive discipline, and there has been significant progress in this field in the past two decades. Compared to other engineering disciplines, SE is not affirmed by a set of underlying fundamental propositions, instead it has emerged as a set of best practices to deal with intricacies stemming from the stochastic nature of engineering complex systems and addressing their problems. Since the existing methodologies and paradigms (dominant pat- terns of thought and concepts) of SE are very diverse and somewhat fragmented. This appears to create some confusion regarding the design, deployment, operation, and application of SE. The purpose of this paper is 1) to delineate the development of SE from 1926-2017 based on insights derived from a histogram analysis, 2) to discuss the different paradigms and school of thoughts related to SE, 3) to derive a set of fundamental attributes of SE using advanced coding techniques and analysis, and 4) to present a newly developed instrument that could assess the performance of systems engineers. More than Two hundred and fifty different sources have been reviewed in this research in order to demonstrate the development trajectory of the SE discipline based on the frequency of publication.

Abstract (sommario):

Earth System Dynamic Intelligence (ESDI) entails developing and making innovative use of emerging concepts and pathways in mathematical geophysics, Earth System Dynamics, and information technologies to sense, monitor, harness, analyze, model and fundamentally unveil dynamic understanding across the natural, social and technical geosciences, including the associated manifold multiscale multidomain processes, interactions and complexity, along with the associated predictability and uncertainty dynamics. The ESDI Flagship initiative ignites the development, discussion and cross-fertilization of novel theoretical insights, methodological developments and geophysical applications across interdisciplinary mathematical, geophysical and information technological approaches towards a cross-cutting, mathematically sound, physically consistent, socially conscious and operationally effective Earth System Dynamic Intelligence. Going beyond the well established stochastic-dynamic, information-theoretic, artificial intelligence, mechanistic and hybrid techniques, ESDI paves the way to exploratory and disruptive developments along emerging information physical intelligence pathways, and bridges fundamental and operational complex problem solving across frontier natural, social and technical geosciences. Overall, the ESDI Flagship breeds a nascent field and community where methodological ingenuity and natural process understanding come together to shed light onto fundamental theoretical aspects to build innovative methodologies, products and services to tackle real-world challenges facing our planet.

The effects of climate-related natural hazards pose a significant threat to sustainable development in Latin America and the Caribbean (LAC) region and in particular its transportation sector. Risk Management provides an appropriate framework for assessing and mitigating the impacts of climate change and other climate-related natural hazards on transportation systems and choosing actions to enhance their resilience. However, analysts and policymakers involved in transportation planning, policy, and investment face significant challenges in managing the risks triggered by the effects of climate change. Climate change impacts the lifespan of roads, airports, and railroads as they have time horizons that surpass 40 years, thus making it harder (if not impossible) to forecast with confidence all relevant future events that will affect such infrastructure. In addition, the climate has already changed, so the return frequency of storms, for example, and other extreme events may now be different than suggested by the historical record in ways that are not always currently well understood. Implementing Risk Management under conditions of such uncertainty can prove difficult. Decision Making Under Deep Uncertainty (DMDU) enables Risk Management under conditions of Deep Uncertainty, that is when risks cannot confidently be quantified. This guidebook is aligned with the Disaster and Climate Change Risk Assessment Methodology for IDB projects (IDB 2018) and introduces and provides guidance on applying methods for Decision Making Under Deep Uncertainty (DMDU) to transportation planning. It presents the methodological steps that are necessary for the implementation of DMDU methodologies and reviews several such methods, including scenario planning, Adaptive Pathways, and robust decision making (RDM). This review is geared towards supporting the incorporation of DMDU methods into IDBs transportation sector funding and planning processes.

Abstract (sommario):

A fundamental responsibility of the National Park Service is to ensure that park resources are preserved, protected, and managed in consideration of the resources themselves and for the benefit and enjoyment by the public. Through the inventory, monitoring, and study of park resources, we gain a greater understanding of the scope, significance, distribution, and management issues associated with these resources and their use. This baseline of natural resource information is available to inform park managers, scientists, stakeholders, and the public about the conditions of these resources and the factors or activities which may threaten or influence their stability. There are several different categories of geologic or stratigraphic units (supergroup, group, formation, member, bed) which represent a hierarchical system of classification. The mapping of stratigraphic units involves the evaluation of lithologies, bedding properties, thickness, geographic distribution, and other factors. If a new mappable geologic unit is identified, it may be described and named through a rigorously defined process that is standardized and codified by the professional geologic community (North American Commission on Stratigraphic Nomenclature 2005). In most instances when a new geologic unit such as a formation is described and named in the scientific literature, a specific and well-exposed section of the unit is designated as the type section or type locality (see Definitions). The type section is an important reference section for a named geologic unit which presents a relatively complete and representative profile for this unit. The type or reference section is important both historically and scientifically, and should be recorded such that other researchers may evaluate it in the future. Therefore, this inventory of geologic type sections in NPS areas is an important effort in documenting these locations in order that NPS staff recognize and protect these areas for future studies. The documentation of all geologic type sections throughout the 423 units of the NPS is an ambitious undertaking. The strategy for this project is to select a subset of parks to begin research for the occurrence of geologic type sections within particular parks. The focus adopted for completing the baseline inventories throughout the NPS was centered on the 32 inventory and monitoring networks (I&M) established during the late 1990s. The I&M networks are clusters of parks within a defined geographic area based on the ecoregions of North America (Fenneman 1946; Bailey 1976; Omernik 1987). These networks share similar physical resources (geology, hydrology, climate), biological resources (flora, fauna), and ecological characteristics. Specialists familiar with the resources and ecological parameters of the network, and associated parks, work with park staff to support network level activities (inventory, monitoring, research, data management). Adopting a network-based approach to inventories worked well when the NPS undertook paleontological resource inventories for the 32 I&M networks. The network approach is also being applied to the inventory for the geologic type sections in the NPS. The planning team from the NPS Geologic Resources Division who proposed and designed this inventory selected the Greater Yellowstone Inventory and Monitoring Network (GRYN) as the pilot network for initiating this project. Through the research undertaken to identify the geologic type sections within the parks of the GRYN, methodologies for data mining and reporting on these resources was established. Methodologies and reporting adopted for the GRYN have been used in the development of this type section inventory for the Chihuahuan Desert Inventory & Monitoring Network. The goal of this project is to consolidate information pertaining to geologic type sections which occur within NPS-administered areas, in order that this information is available throughout the NPS...

Abstract (sommario):

The main recommendations of the panel report can be summarised under five key headings:  Building blocks: The ultimate aim should be to build rich, detailed and testable narratives situated within a European context, and addressing phenomena from the longue durée to the short-term over international to local scales. Chronological control is essential to this and effective dating strategies are required to enable generation-level analysis. The ‘serendipity factor’ of archaeological work must be enhanced by recognising and getting the most out of information-rich sites as they appear. o There is a pressing need to revisit the archives of excavated sites to extract more information from existing resources, notably through dating programmes targeted at regional sequences – the Western Isles Atlantic roundhouse sequence is an obvious target. o Many areas still lack anything beyond the baldest of settlement sequences, with little understanding of the relations between key site types. There is a need to get at least basic sequences from many more areas, either from sustained regional programmes or targeted sampling exercises. o Much of the methodologically innovative work and new insights have come from long-running research excavations. Such large-scale research projects are an important element in developing new approaches to the Iron Age.  Daily life and practice: There remains great potential to improve the understanding of people’s lives in the Iron Age through fresh approaches to, and integration of, existing and newly-excavated data. o House use. Rigorous analysis and innovative approaches, including experimental archaeology, should be employed to get the most out of the understanding of daily life through the strengths of the Scottish record, such as deposits within buildings, organic preservation and waterlogging. o Material culture. Artefact studies have the potential to be far more integral to understandings of Iron Age societies, both from the rich assemblages of the Atlantic area and less-rich lowland finds. Key areas of concern are basic studies of material groups (including the function of everyday items such as stone and bone tools, and the nature of craft processes – iron, copper alloy, bone/antler and shale offer particularly good evidence). Other key topics are: the role of ‘art’ and other forms of decoration and comparative approaches to assemblages to obtain synthetic views of the uses of material culture. o Field to feast. Subsistence practices are a core area of research essential to understanding past society, but different strands of evidence need to be more fully integrated, with a ‘field to feast’ approach, from production to consumption. The working of agricultural systems is poorly understood, from agricultural processes to cooking practices and cuisine: integrated work between different specialisms would assist greatly. There is a need for conceptual as well as practical perspectives – e.g. how were wild resources conceived? o Ritual practice. There has been valuable work in identifying depositional practices, such as deposition of animals or querns, which are thought to relate to house-based ritual practices, but there is great potential for further pattern-spotting, synthesis and interpretation. Iron Age Scotland: ScARF Panel Report v  Landscapes and regions:  Concepts of ‘region’ or ‘province’, and how they changed over time, need to be critically explored, because they are contentious, poorly defined and highly variable. What did Iron Age people see as their geographical horizons, and how did this change?  Attempts to understand the Iron Age landscape require improved, integrated survey methodologies, as existing approaches are inevitably partial.  Aspects of the landscape’s physical form and cover should be investigated more fully, in terms of vegetation (known only in outline over most of the country) and sea level change in key areas such as the firths of Moray and Forth.  Landscapes beyond settlement merit further work, e.g. the use of the landscape for deposition of objects or people, and what this tells us of contemporary perceptions and beliefs.  Concepts of inherited landscapes (how Iron Age communities saw and used this longlived land) and socal resilience to issues such as climate change should be explored more fully.  Reconstructing Iron Age societies. The changing structure of society over space and time in this period remains poorly understood. Researchers should interrogate the data for better and more explicitly-expressed understandings of social structures and relations between people.  The wider context: Researchers need to engage with the big questions of change on a European level (and beyond). Relationships with neighbouring areas (e.g. England, Ireland) and analogies from other areas (e.g. Scandinavia and the Low Countries) can help inform Scottish studies. Key big topics are: o The nature and effect of the introduction of iron. o The social processes lying behind evidence for movement and contact. o Parallels and differences in social processes and developments. o The changing nature of houses and households over this period, including the role of ‘substantial houses’, from crannogs to brochs, the development and role of complex architecture, and the shift away from roundhouses. o The chronology, nature and meaning of hillforts and other enclosed settlements. o Relationships with the Roman world
