Introduction

Software Product Line (SPL) migration remains a challenging endeavour

From organizational issues to purely technical challenges, there is a wide range of barriers that complicates SPL adoption.
This workshop aims to foster research about making the most of the two main inputs for SPL migration:
1) domain knowledge and 2) 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 or extract the reusable software components.
Legacy assets can be, for instance, similar product variants (e.g. requirements, models, source code etc.) that were implemented using ad-hoc reuse techniques such as clone-and-own.
More generally, the workshop REverse Variability Engineering (REVE) attracts researchers and practitioners contributing to

processes, techniques, tools, or empirical studies related to the automatic, semi-automatic or manual extraction or refinement of SPL assets.

Speaker: Paul Grünbacher
Risks and Opportunities of the Research Loop in Variability Engineering
Abstract: A typical research approach in software engineering is to lift engineering challenges into abstract problems, solving them, and applying the results. The keynote talk will explore this research loop in the context of (reverse) variability engineering. Based on ideas of John Regehr's interesting blog article (https://blog.regehr.org/archives/1582) the talk will discuss research risks and research opportunities: in particular, moving from concrete to abstract can be risky in variability engineering if the abstractions are no longer relevant for the real-world challenges to be addressed. Moving from abstract to concrete on the other hand often means solving real engineering problems but can also provide new insights leading to research opportunities. The talk will report lessons learned from working with different industry partners in the domain of variability engineering. It will cover areas such as variability modelling, variability and evolution, variability-aware analysis, as well as software process issues.
Shortbio: Paul Grünbacher is an Associate Professor and Deputy Head at the Institute of Software Systems Engineering at Johannes Kepler Universität Linz (Austria). His research interests include software product lines, model-based development and evolution, requirements engineering, and software monitoring. Over the last 15 years Paul has been heading research projects in these areas with partners from the industry. Paul is an Editorial Board Member of the Empirical Software Engineering Journal (Springer) and the Information and Software Technology Journal (Elsevier). He is regularly serving as a reviewer for international journals and conferences. He is member of ACM, ACM SIGSOFT, the IEEE CS, the Austrian Computer Society, and Euromicro.
