The next step in defining a process model is to then define the Model Hierarchy.  The hierarchy is different from company to company.

Business process can be specified in terms of level of detail.  Each level is typically made-up of 3 to 12 definable work groupings.  As defined earlier with the process levels, a generic process model hierarchy along with process levels is shown below.
