Reusable SW Requirements Development Process: Embedded SW Industry Experiences

Embedded system development confronts to the needs of guaranteeing both short time release and the product´s high quality. Emphasizing proactive SW reuse, it is necessary to identify reusable SW requirements for the product families. Once the standard features of product family are defined as reusable requirements, a derived model reuses most of them and adds little efforts on specifying new requirements. Its reuse can also smoothly make design models, implementation code, and corresponding test cases be reusable. This paper focuses on the systematic management process of developing reusable SW requirements for the embedded product families; we define the feature as the requirement unit; propose reusable requirements development process (RRDP); finally evaluate our process applying to industrial practices.
