Usage Scenarios for a Common Feature Modeling Language

• Feature models are recognized as a de facto standard for variability modeling. Presented almost three decades ago, dozens of different variations and extensions to the original feature-modeling notation have been proposed, together with hundreds of variability management techniques building upon feature models. Unfortunately, despite several attempts to establish a unified language, there is still no emerging consensus on a feature-modeling language that is both intuitive and simple, but also expressive enough to cover a range of important usage scenarios. There is not even a documented and commonly agreed set of such scenarios. Following an initiative among product-line engineering researchers in September 2018, we present 14 usage scenarios together with examples and requirements detailing each scenario. The scenario descriptions are the result of a systematic process, where members of the initiative authored original descriptions, which received feedback via a survey, and which we then refined and extended based on the survey results, reviewers' comments, and our own expertise. We also report the relevance of supporting each usage scenario for the language, as perceived by the initiative's members, prioritizing each scenario. We present a roadmap to build and implement a first version of the envisaged common language.
