A BPMN 2.0 Extension to Define the Resource Perspective of Business Process Models

One of the primary motivations of BPMN is to provid e an easy to understand standard way to define and visualize bus ines process models. This goal is addressed with respect to the control flow perspective. However, the support it provides to the resource perspective is poor. This work presents an extension to the BPMN 2.0 metamodel and notation to support the modeling and visualization of resource perspective requireme nts. It considers three aspects of the resource perspective: resource struc ture, authorization and work distribution. This extension is validated against t he Workflow Resource Patterns that define recurrent requirements regardi ng this perspective. The aim of this BPMN extension is to improve the communicati on of the resource perspective requirements between business analysts nd technical developers.
