Incremental migration to software product line engineering
Sten Grüner, Andreas Burger, Tuomas Kantonen, Julius Rückert · 2020
Current market developments require organizations to produce high-quality tailored software variants while simultaneously coping with increased software complexity. Software Product Line Engineering (SPLE) is a well-known approach to manage this variability and complexity, however no step-wise migration process is available allowing a co-existence of SPLE along with established development processes. In this paper, we introduce an incremental SPLE migration strategy and process starting from using the feature model as synchronized product and variant documentation. They can be applied as a first step of SPLE migration along with the continuous software development cycle. We performed initial steps of the process on industrial low voltage drive embedded firmware spanning around few millions lines of code using a commercial SPLE tool and validated short-term benefits by means of stakeholder feedback.
