1. Modeling Tool: Use BPMN 2.0 to specify the process models. 2. Perspectives: Capture the three main perspectives (i.e., control-flow, data, and resourc perspectives) of the process in the process models. 3. Hierarchy: Present the hierarchy of process models, illustrating the positioning of the proces models at different levels of abstraction. : 1- 2- 3- 4- 6- 7- 8- 8- 9- 10- 1.
