Visualizing complex business processes is an important task of process-aware information systems (PAIS). Current PAIS, however, fail in providing adequate mechanisms for visualizing and monitoring business processes. In particular, PAIS do not support person- alized or adaptable process drawings, which is par- ticularly important for large processes. In the Pro- viado project we are developing a comprehensive framework for this purpose. It allows for flexible proc- ess visualization along three dimensions: process views, process notations, and process representation forms. In this paper we summarize selected concepts and features of the Proviado demonstrator.
