Software Product Line Variability Management

Software product line engineering (SPLE) is the approach for creating a diversity of similar products at low cost, in short time, and with high quality. Explicitly documenting product line variability is essential for variability management as it significantly supports the following activities: Defining the commonality and the variability of the product line during domain engineering; Realizing reusable artifacts (the domain artifacts) with variability; Defining the binding of variability during application engineering; Deriving individual applications by exploiting the variability in the domain artifacts. This tutorial is based on our text book on software product line engineering [1]. The tutorial is structured along an SPLE framework, which has been defined based on our experiences and the results of the European software product line research projects ESAPS, CAFÉ, and FAMILIES [2].
