Expressing Feature-Based Variability in Structural Models
Software product line engineering aims at reducing
development time, effort, cost, and complexity by taking
advantage of the commonality within a portfolio of
similar products. The effectiveness of a software product
line approach directly depends on how well feature
variability within the portfolio is implemented and managed
throughout the development lifecycle, from early
analysis through maintenance and evolution. This paper
presents a tool-supported approach that improves
variability management and tracing by providing
means to express feature-based variability on model
level. Features are separated in models and automatically
composed. The approach supports both positive
variability, i.e. adding optional parts to a model, as
well as negative variability, i.e. removing parts from a
model. Tools are provided that implement the presented
concepts. The approach is illustrated with a
case study of a home automation system.
