Creating Domain Non-functional Requirements Software Product Line Engineering Using Model Transformations
Fatima Khalique, Wasi Haider Butt, Shoab Ahmad Khan · 2017
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.
