From Integration to Composition: On the Impact of Software Product Lines, Global Development and Ecosystems

Three trends accelerate the increase in complexity of large-scale software development, i.e. software product lines, global development and software ecosystems. For the case study companies we studied, these trends caused several problems, which are organized around architecture, process and organization, and the problems are related to the efficiency and effectiveness of software development as these companies used too integration-centric approaches. We present five approaches to software development, organized from integration-centric to composition-oriented and describe the areas of applicability
