A pattern based approach for requirements engineering

This paper presents a pattern-oriented approach to requirements engineering. It proposes an OrganizationDiagnosis pattern language which attempts to represent the fundamental elements intervening recurrently during requirements engineering elicitation. The idea is to propose components that enable to reuse the solutions for recurrent problems to which analysts are confronted in software engineering. Therefore, we propose to capitalize the now-how in requirements engineering by adopting a pattern based approach. The analyst can select components that he judges relevant for its application and adapt them to its context. Each pattern describes the problem, its context and the solution in a semi-formal language. Our approach identifies a set of patterns that can serve as nucleus to elaborate the system analysis. An illustration of the OrganizationDiagnosis pattern language is given through an application of order management.
