A rule-based method for detecting the missing common requirements in software product line

The problem of incomplete requirements has been one of the most critical issues in requirements engineering. Common requirements in the software product line establish the foundation to implement the core functionalities of a family of software products. In this paper, we propose a framework to detect the missing common requirements in the context of software product line. The framework mainly consists of two parts: a set of rules to extract the common requirements, the dependency relationships among them and a procedure for detecting the omission in an incoming set of requirements. Preliminary experiments are conducted on a group of medical applications to validate our approach. The results indicate that our proposed framework is effective.
