Process Activity Model


A Process Activity Model shows the relationship of the related activities and their use of information. This model is typically used to understand / analyze the activities within a single process. These activities form the basis for Role identification and related training.


There are many types of models that cover the formal relationships of activities. These are:

  • BPMN
  • Activity Diagrams (UML)
  • IDEF
  • DataFlow diagrams

Some use swim lanes to highlight the roles carrying out the work (BPMN / UML).

Each of the above standard models has a corresponding set of definitions to create them.

Note: Informal diagrams that are more understandable by a set of stakeholders are also in this set and must be based upon a formal model.

Note: These activity models also need to provide a way to identify a "System Interaction Point".

The Soft Systems Methodology (SSM) problem solving approach is a good approach for both identifying the activity model and the issues surrounding the implementation / changes necessary to implement the benefits.
