A Customizable SPL Scoping Process for SPL Reengineering

Software Product Lines (SPL) are a well known solution to systematically create reusable software products. SPL reengineering emerges as a strategy for obtaining SPL from a set of legacy systems. As there are different scenario variables, such as, available artifacts and team experience, the activities and techniques used to perform reengineering tasks may change, requiring that approaches provide some customization to user’s scenarios. In this context, SPL scoping is important for defining domain variables used for decisions, intending to improve the cost benefit of SPL. However, there is a lack of a process supporting these tasks considering different scenarios. Therefore, we specify Prepare, Assemble and Execute Process for SPL Reengineering (PAxSPL), a process that provides support to prepare, assemble and execute feature retrieval while also considering SPL scoping concepts and activities. In this work, we present our approach and perform a comparison to related works showing that PAxSPL customization may reduce effort of adoption in user’s scenarios.
