The main goal of business process performance analysis has always been to analyze the performance of business processes in order to improve them. Studies on the topic have been focused mostly on obtaining the appropriate information from a process, while somewhat neglecting the way in which to provide it to the end-user. In this case proper visualization of the information can help to identify problems in the process or how and where to improve it.

In this thesis a visualization approach is investigated to provide process performance information to the user in an intuitive and interactive manner. Existing solutions to the problem are researched to identify strengths and weaknesses. Given the outcomes of this research an approach is proposed to visualize the process performance information. The approach uses a Multiple Coordinated Views design, combining two stand-alone views to one interactive visualization. The views consist of a workflow view, displaying the process itself while mapping information onto it, and an organizational, resource view, displaying the resources that play a role in the process as well as relations between these resources. To evaluate the proposed approach, a prototype has been implemented in the Axxerion software and tested using sample and real-life data. Evaluation of the prototype and a feedback session with consultants working in the domain indicate that the approach provides an interactive and intuitive way to dynamically inspect the performance of business processes.
