Abstract
Software product lines (SPL) aim at facing the increasing costs of software products by reusing core assets of existing products in a given domain. They are often described using feature models which, as we proposed in a previous work, can be built from possibly incomplete, documented UML use case diagrams assets using the Formal Concept Analysis method, semantic model and trigger model. In order to evaluate this approach, we present in this paper the UC2FM-tool which automates all its steps. In addition, we report on a comparison of the values of quality metrics of feature models produced by our approach with those of existing feature models built by experts for five different domains.
