A monitoring component is a much-needed module in order to provide an integrated view on system-spanning and cross-organizational business processes. Current monitoring tools, however, do not offer adequate process visualization support. In particular, processes are always visualized in the way they were drawn by the process designer. This static approach is by far not sufficient when dealing with more complex scenarios where different user groups usually have different perspectives on processes and related data. In such an environment different views and personalized visualizations have to be provided. In the Proviado project we are developing a framework for realizing flexible and adaptable visualizations of business processes whose data may be scattered over multiple information systems. In this paper we focus on personalization and configuration issues, and we show how process visualizations can be adapted automatically, e.g., by applying different notations for different user groups or by altering the appearance of visualized elements depending on their execution state. For this purpose we define a visualization model which maintains all required visualization parameters.
