You can use the Business Process Modeling Notation (BPMN) to model the NOV-5 view, as an alternate to using IDEF0.
Prerequisite
You must first select BPMN notation as the default notation for NOV-5 diagrams in the project encyclopedia.
Note In the default NAF 3.0 configuration, the NOV-05 Activity Model is a BPMN diagram, in which you place the Operational Activity symbols in the associated node. Additionally, the Operational Activities property in the Operational Node definition should be filled in and manually kept in synch with the diagram.
When using the BPMN, you can link Operational Activities to Business Processes, model Information Exchanges as Message Flow lines between processes in different pools, and attach Information Exchanges as Data Objects to Sequence Flow lines.
Procedure
1 Create an NOV-5 diagram.
2 Model the operational workflow:
▪Add processes to the NOV-5 diagram.
▪In the MODAF tab of the BPMN process, specify an operational activity for each process.
3 Model workflow between processes using the Sequence Flow line.
Note To model work flow between processes that are in different Pools, use the Message Flow line.
4 To specify information exchanged over a Sequence Flow line, use the Information Exchange symbol (in BPMN called a Data Object), and connect it to the line.
▪Select the Information Exchange symbol from the toolbar, and draw it on the diagram.
▪Press Ctrl, and simultaneously select the Information Exchange symbol and the Sequence Flow line you want to attach it to.
▪Select Draw > Associate Information Exchange with Sequence Flow. (Or right‑click and then click Associate Information Exchange with Sequence Flow.)
5 Draw Message Flow lines between processes in different Pools to define Information Exchanges; the Message Flow lines convert to Information Exchanges.
You can only draw Message Flows between processes that exist in different Pools. You cannot draw a Message Flow line between Processes that are in the same Pool.
The following image shows an example of an OV-5 diagram modeled with BPMN.
