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 personalized or adaptable process drawings, which is particularly important for large processes. In the Proviado project we are developing a comprehensive framework for this purpose. It allows for flexible process 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.
