First international workshop on Multi Product Line Engineering (MultiPLE 2013)

In an industrial context, software systems are rarely developed by a single organization. For software product lines, this means that various organizations collaborate to provide and integrate the assets used in a product line. It is not uncommon that these assets themselves are built as product lines, a practice which is referred to as multi product lines. This cross-organizational distribution of reusable assets leads to numerous challenges, such as inconsistent configuration, costly and time-consuming integration, diverging evolution speed and direction, and inadequate testing. The MultiPLE workshop is aimed at discussing the challenges involved with the development and evolution of multi product lines and the assets used for their production. © 2013 Authors.
