Abstract

In previous work we show how abstract delta modeling can be used to model product lines. The formalism assigns a functional meaning to features from a feature model and provides a novel mechanism for resolving implementation conflicts without code duplication or overspecification. But in the vast expressive space of delta modeling, it may not be clear to a developer how to create a product line from scratch. The formalism was descriptive rather than prescriptive. To that end, we propose a development workflow based directly on Abstract Delta Modeling. We show preservation of global unambiguity and completeness in the product lines resulting from this workflow. We also show that the work-flow naturally supports concurrent development.
