Building and Reusing of Requirements Repository

Computer Engineering Dept., College of Engineering, Arab Academy for Sci. & Tech., Dec 2005.

This project suggests a new approach to requirements analysis intended to maximize reuse, and thus increase productivity and requirements specifications quality. Such benefits can be gained by reusing requirements from the existing software applications. Alternatively, reusable requirements representations could be identified and utilized in the process of refining software requirements for a single new application.
In this research work, we used the application family concept for addressing the technological issues of concern to both requirements engineering and software reuse and uses it as the basis for developing a cohesive requirements reuse process. It shows that this concept could be instantiated into a practical object oriented method for requirements authoring and management (OOMRAM) and embedded in a web based software tool (Requirements Repository). The resulting method-tool pair was developed to support analysts in developing a domain model, and then using the model in requirements analysis, reuse and refinement.
One of the main problems in requirements refinement is the effective matching of requirements which may be stored in a repository. A major contribution of this work is to deal with this difficulty and to develop an approach facilitate requirement of classifying, comparing, searching and retrieving requirements sourced in a repository.

We developed a requirement representation model to facilitate the classification of requirements and its retrieval using an application family concept. Also, we developed a method of calculating similarity between family members. This proposed approach able to help the software engineer in managing changes in requirements easily and avoid the problems of unsatisfied, impractical and/or unnecessarily requirements.
