Using Composite Feature Models to Support Agile Software Product Line Evolution

Managing continuous change in a Software Product Line (SPL) is one of the challenges now faced by the SPL en- gineering community. On the one hand, the SPL paradigm captures the intrinsic variability of a software based on a sys- temic vision of the software to model. On the other hand, Agile Software Development advocates the incremental de- velopment of software based on constant interaction with a customer community. In this paper, we present an approach based on Composite Feature Models (CFM) to support the agile evolution of a SPL. This study is driven by the refac- toring of a daily used application (information broadcasting system), in the context of a nationally funded project. Pre- liminary results show that CFMs support the incremental development of a SPL based on interactions with a commu- nity, tackling the challenge of SPL continuous evolution.
