Combining reverse engineering techniques for product lines

In a product line context, the migration strategy to exploit functionality embodied in existing components having a high reuse potential can be fourfold: reuse as is, reuse and adapt, recover and reconstruct, or (re-)implement. This position paper focuses on the recover and reconstruct strategy and presents an integrated architecture reconstruction approach that aims at migrating core functionality, major variants and key features of existing systems into a product line infrastructure. We combine dynamic and static reverse engineering techniques within a systematic reconstruction approach, whereby one of the main goals is to be compliant to the product line architecture. In this paper, we present the reconstruction approach and illustrate the technique interactions techniques in a case study.
