Using traceability for incremental construction and evolution of software product portfolios

Software reuse has become mandatory for companies to compete and a wide range of reuse techniques are available today. Despite the great benefits of these techniques, they also have the disadvantage that they do not necessarily support the creation and evolution of closely related products -- products that are customized to different infrastructures, ecosystems, machinery, or customers. In this paper we outline an approach for incrementally constructing and evolving software product portfolios of similar product variants. An initial proof of concept demonstrates its feasibility.
