Methodology for Software Requirements Elicitation and Analysis

Requirements Engineering (RE) is a sub-discipline§within Software Engineering increasingly recognized§as a critical component in the success of a software§development project. With the escalating complexity§of software requirements, problems of traditional§requirements engineering techniques, including the§use of natural language text, are becoming§increasingly apparent.This research aims to assist§software analysts in dealing with the challenges that§exist in correctly understanding user requirements§during the interactive process of requirement§elicitation and analysis. It proposes a methodology§related to visualization of textual requirements and§ways of making them shared, reviewed and debated by§the stakeholders. The approach is based on a§syntactic analysis and formalization of the text§written in natural language and enriched with§domain-related information extracted from reusable§domain-specific data models. The applicability of§this research is illustrated with a case study. A§prototype implementing our methodology is developed§as a proof-of-concept. The results of controlled§experiments designed to evaluate our approach prove§the validity of the methodology.
