Visualising business processes

Graphical representations of business process models are an important means for business architects to grasp the inherent complexity of business processes. This paper reports on the visualisation features of AMBER, the graphical and formal business process language of the Testbed project, and Testbed Studio, its toolkit. Visualisation features fulfill explicit requirements, which are based on an investigation of a business architect's main activities. The paper presents the three main visualisation areas in Testbed: (1) the graphical representation of the language itself, (2) representation conventions, and (3) a set of business process views.
