Fourth international workshop on reverse variability engineering (REVE 2016)

From organizational issues to purely technical challenges, there is a wide range of barriers that complicates Software Product Line (SPL) adoption. This workshop aims to foster research about making the most of two main inputs for SPL migration: 1) domain knowledge and 2) existing legacy assets. Domain knowledge, usually implicit and spread across an organization, is key to define the SPL scope and to validate the variability model and its semantics. At the technical level, domain expertise is also needed to create reusable software components. Regarding legacy assets, they use to be similar product variants (e.g. requirements, models, source code etc.) that were implemented using ad-hoc reuse techniques such as clone-and-own. These assets can be leveraged in extractive SPL adoption processes. The workshop REverse Variability Engineering (REVE) attracts researchers and practitioners contributing processes, techniques, tools, or empirical studies related to the automatic, semi-automatic or manual extraction or refinement of SPL assets.
