A reuse-based requirements elicitation process

Establishing good requirements is important in an initial phase of software development not to make over time and cost of projects and low quality of software products. In the context of Requirements Engineering (RE), reuse is effective in particular because it can help to define requirement explicitly and to anticipate requirement change. We propose a reuse-based process approach to elicit potential requirements from various stakeholders. To achieve our goal, we present (1) analyzing gaps between requirements maps of collected and reused in the repository, and (2) potential requirements elicitation process with these maps. The former is composed of classifying styles of requirements, requirements representation formalism, and gap analysis using generic gap types. The latter is sequential procedure to look for potential requirements in addition to Plus Minus Interests(PMI) method. We illustrate our approach through a credit system case study.
