This paper addresses the problem of “missing requirements ” in software requirements specification (SRS) expressed in natural language. Due to rapid changes in technology and business frequently witnessed over time, the original SRS documents often experience the problems of missing, not available, and hard-to-locate requirements. One of the flaws in earlier solutions to this problem has no consideration for missing requirements from multiple viewpoints. Furthermore, since such SRS documents represent an incomplete domain model, manual discovery (identification and incorporation) of missing requirements and relationships is highly labor intensive and error-prone. Consequently, deriving and improving an efficient adaptation of SRS changes remain a complex problem. In this paper, we present a new methodology entitled “Proxy Viewpoints Modelbased Requirements Discovery (PVRD)”. The PVRD methodology provides an integrated framework to construct proxy viewpoints model from legacy status requirements and supports requirements discovery process as well as efficient management.
