Extending Feature Models to Express Variability in Business Process Models

In complex organizations Business Processes tends to exist in different variants that typically share objectives and part of their structure. In recent years it has been recognized that the explicit modeling of variability can brings important benefits to organizations that can more easily reflect on their behavior and more efficiently structure their activities and processes. Particularly interesting in this respect is the situation of the Public Administration that delivers the same service using many different and replicated processes. The management of such complexity ask for methods explicitly supporting the modeling of variability aspects for Business Processes. In this paper we present a novel notation to describe variability of Business Processes and an approach to successively derive process variants. The notation takes inspiration from feature modeling approaches and has been implemented in a real tool using the ADOxx platform. The notation, and the corresponding approach, seems particularly suitable for the Public Administration context, and it has been actually experimented in a complex real scenario.
