Abstract
Software Product Lines in general and feature diagrams in particular support the modeling of software variability. Unfortunately, features may interact with each other, leading to feature interaction issues. Even if detected at the implementation level, interaction resolution choices are part of the business variability. In this paper, we propose to use a stepwise process to deal with feature interactions at the domain level: the way an interaction is resolved is considered as a variation point in the configuration process. This method and the associated implementation are applied onto a concrete case study (the jSeduite information system).
