    Interactive situation modelling in knowledge intensive domains

    Get PDF
    Interactive Situation Modelling (ISM) method, a semi-methodological approach, is proposed to tackle issues associated with modelling complex knowledge intensive domains, which cannot be easily modelled using traditional approaches. This paper presents the background and implementation of ISM within a complex domain, where synthesizing knowledge from various sources is critical, and is based on the principles of ethnography within a constructivist framework. Although the motivation for the reported work comes from the application presented in the paper, the actual scope of the paper covers a wide range of issues related to modelling complex systems. The author firstly reviews approaches used for modelling knowledge intensive domains, preceded by a brief discussion about two main issues: symmetry of ignorance and system behaviour, which are often confronted when applying modelling approaches to business domains. The ISM process is then characterized and critiqued with lessons from an exemplar presented to illustrate its effectiveness

    The W Life Cycle Model and Associated Methodology for Corporate Web Site Development

    The last few years witnessed the increasing internal and external use of the Internet by organizations. Web sites grew in sophistication from conventional sites composed of a simple collection of Web pages for public relations or marketing to complex Web information systems dealing with business-to-customer transactions or business-to-business networks. However, most organizations still do not have a formal process of Web site development, and corporate Web sites are often developed in an unorganized and uncoordinated fashion. The results of this chaotic situation include slow delivery, conflicting standards, discrepancies with respect to corporate objectives, and redundant development efforts. To help alleviate this situation, this paper presents the W software life cycle model for corporate web site development along with an associated methodology to guide Web development groups in their endeavors. The proposed process model and methodology are based on insights gleaned by studying development projects for three types of corporate Web sites: intranets, Web-presence sites, and transactional sites. However, because Web information systems are more complex, the article also provides recommendations for how the methodology can be adapted to handle these types of applications better

    Software Engineering Laboratory (SEL) relationships, models, and management rules

    Get PDF
    Over 50 individual Software Engineering Laboratory (SEL) research results, extracted from a review of published SEL documentation, that can be applied directly to managing software development projects are captured. Four basic categories of results are defined and discussed - environment profiles, relationships, models, and management rules. In each category, research results are presented as a single page that summarizes the individual result, lists potential uses of the result by managers, and references the original SEL documentation where the result was found. The document serves as a concise reference summary of applicable research for SEL managers

    Into the future : inspiring and stimulating users\u27 creativity

    This paper proposes a new approach to engaging and stimulating users in the requirements analysis process when developing a new information system &ndash; an ICT innovation for business. The approach is based on a synthesis of a constructivist learning theory and a creativity education theory. In contrast to previous approaches in which the systems analyst elicits requirements from the user, in the proposed approach, the user is engaged and stimulated to become a proactive and creative learner in the process of identifying and discovering their business problem as well as exploring opportunities to apply ICT innovations to solve the problem.Two experiential digital simulations are described as a proof of concept to demonstrate the proposed approach a learning environment. Learning from the case study suggests that both systems analyst and business users can be stimulated to be active learners in their discovery of problem, creative ideas and problem solutions in requirements elicitation and discovery.<br /

    Requirements elicitation: A survey of techniques, approaches, and tools

    Full text link
    Requirements elicitation is the process of seeking, uncovering, acquiring, and elaborating requirements for computer based systems. It is generally understood that requirements are elicited rather than just captured or collected. This implies there are discovery, emergence, and development elements in the elicitation process. Requirements elicitation is a complex process involving many activities with a variety of available techniques, approaches, and tools for performing them. The relative strengths and weaknesses of these determine when each is appropriate depending on the context and situation. The objectives of this chapter are to present a comprehensive survey of important aspects of the techniques, approaches, and tools for requirements elicitation, and examine the current issues, trends, and challenges faced by researchers and practitioners in this field. © 2005 Springer-Verlag Berlin Heidelberg

    Requirement elicitation and knowledge management utilizing relational database, client server and internet technologies

    Get PDF
    The first step in any project is a statement of requirements. Requirements specification is an inevitable part of any successful project. However, the rush to convert concepts to products often proves as a big hindrance in the development process of any requirements set. This, in turn, hampers the ability to produce the concept and manage knowledge as originally envisioned. The goal of the thesis is to foster understanding among the different communities affected by the development of the given system. The thesis is based on the principle that the requirements elicitation process for complex system is fundamentally a conversation among the stakeholders that is designers, customers and implementers. The web based tool developed for requirements elicitation allows the stakeholders to pool their respective expertise and viewpoints to resolve requirement issues. This leads to consensus building among the stakeholders and also provides with well-defined, clear, and concise requirements set. The requirements gathered by the tool can help determine the source, applicability, depth, and other factors needed for assessing and implementing integrated, and coherent, requirements set. It also helps the design team identify whether a specific requirement establishes a quantifiable threshold. Moreover, the tool uses the latest technologies of client server architecture, relational database and Internet. This make the tool efficient, portable, easy to debug. The three tier architecture of the tool also facilitates the ease in enhancement. The thesis also emphasizes that research efforts should be directed towards methods and tools needed to improve requirements analysis process and in particular o those providing more support to the elicitation of requirements. A simple lesson that can be learnt is that no one person knows everything about what a system should do. There are always many participants in a successful requirement elicitation effort
