We propose an approach for managing configurable Business Processes (cBP) that offer a consolidated view over these processes’ variants. A variant is the result of adjusting a BP in response to functional and/or structural needs. The approach uses a knowledge base to track the specificities of each variant that is represented as configurable Process Structure Tree (cPST).  An implementation of the approach that consists of generating a cPST from a cBP is proposed. We apply this approach to compute configurable business process complexity and to prove its advantage for improving cBP quality.
