Creating Domain Non-functional Requirements Software Product Line Engineering Using Model Transformations

Requirement Engineering (RE) process during product development produces core artifacts to be analyzed during domain analysis phase of Software Product Line Engineering (SPLE). The product RE process can be a Software Requirement Specification (SRS) document, use case models or other artifacts containing both functional and nonfunctional requirements of the product. The analysis of these artifacts is a time consuming and error-prone process when performed manually. There is also a need for creating consistent and complete set of non-functional requirements from user-specific individual projects in SPL. Therefore, we propose a methodology to create Domain Non-Functional Requirements (DNFRs) from Product Non-Functional Requirements (PNFRs) using model driven approach. Two model transformations are performed to automate the process of DNFR creation. First transformation converts PNFR into Product Line Non-Functional Requirements (PLNFR) using a PNFR meta model. The second transformation converts the PLNFR into DNFR using DNFR meta model. This transformation exploits commonality and variability among the products in terms of their non-functional requirements. The resulting DNFR can serve as a useful baseline for domain analysis in SPLE.
