|Abstract: ||Software Product Line (SPL) has emerged as an important strategy to cope with the increasing demand of large-scale products customization. SPL has provided companies with an efficient and effective means of delivering products with higher quality at a lower cost, when compared to traditional software engineering strategies. However, such benefits do not come for free.
There is a necessity in SPL to deal with the evolution of its assets to support changes within the environment and user needs. These changes in SPL are firstly represented by requirements. Thus, SPL should manage the commonality and variability of products by means of a “Requirements Engineering (RE) - change management” process. Hence, besides dealing with the reuse and evolution of requirements in an SPL, the RE for SPL also needs an approach to represent explicitly the commonality and variability information (e.g., through feature models and use cases).
To understand the evolution in SPL, this Thesis presents two empirical studies within industrial SPL projects and a systematic mapping study on SPL evolution. The two empirical studies evaluated Lehman’s laws of software evolution in two industrial SPL projects,demonstrating that most of the laws are supported by SPL environments. The systematic mapping study on SPL evolution identified approaches in the area and revealed gaps for researching, such as, that most of the proposed approaches perform the evolution of SPL requirements in an ad-hoc way and were evaluated through feasibility studies.
These results led to systematize, through guidelines, the SPL processes by starting with the SPL requirements. Thus, it was proposed an approach to specify SPL requirements called Feature-Driven Requirements Engineering (FeDRE). FeDRE specifies SPL requirements in a systematic way driven by a feature model. To deal with the evolution of FeDRE requirements, a new approach called Feature-Driven Requirements Engineering Evolution (FeDRE2) was presented. FeDRE2 is responsible for guiding, in a systematic way, the SPL evolution based on activities from RE.
Both proposed approaches, FeDRE and and FeDRE2, were evaluated and the results, besides being preliminaries, shown that the approaches were perceived as easy to use and also useful, coping with the improvement and systematization of SPL processes.|
