Business Process Modeler allows process modeling and analyzing through the Diagram view. In certain situations, this procedure can be cumbersome, as there is a learning curve involved for the business user, who needs to understand the usage and semantics of BPMN shapes before defining a meaningful process.
Consider an instance where a business user wants to quickly outline a large process with a large number of tasks. Instead of adding shapes and defining their properties in the Diagram view, a business user would probably rather work with a project-oriented view of the process by defining a set of tasks, the task/subtask relationships, and additional details without ever needing to switch to the Diagram view. The Diagram view is still a useful view especially for complex flows. However, it is not the only view, nor is it the only editor for defining new worksteps. Business Process Modeler provides the Overview page, which is an effective tool to support project-oriented processes.
