Item An Effective Approach To Requirements Engineering For Information Systems Consulting(2017-01-01) Tefera, Netsanet Legesse; Zhang, Dongsong; Information Systems; Information SystemsInformation system (IS) consulting methodologies have evolved to reduce the failure of IS projects. Most studies attribute the failure of IS projects to incorrectly gathered requirements by IS consultants for different reasons, including the lack of effective requirements engineering (RE) methodologies, communication challenges between consultants and their clients, and a consultant's experience in the field. This theses proposes an Effective Requirements Engineering Methodology (EREM) conceptual system to solve those issues. Indeed, EREM incorporates the various key RE components into one mobile collaborative system, which simplifies communication between consultants and their clients. The elicitation, analysis, documentation, validation, and management steps are performed simultaneously, by displaying self-explanatory form-like guides, scoring instruments, and visual representations. Also, the proposed approach's success is independent of a consultant's experience in the field. A case study at a medium sized nonprofit organization was conducted to demonstrate EREM's practical implications.Item Building Information Systems Development Methods: Synthesising from a Basis in both Theory and Practice(IEEE, 2002) Fowler, Danielle; Swatman, Paul AnthonyIn this paper, we discuss some methodological issues associated with research into requirements engineering, and describe the benefits afforded to us by using action research to explore issues associated with requirements elicitation, modelling and validation. FOOM is a requirements engineering method which is designed to facilitate the development of high-quality, requirements-conformant information systems. In creating FOOM, an overriding concern has been to ensure both theoretic soundness and practical applicability within the target domain. We discuss in this paper the benefits of using action research as an enquiry mechanism for exploring issues associated with requirements elicitation, modelling and validation, and the way in which it formed a central part of the method's evaluation and evolution.
