OV-5b – Operational Activity Model

Download PDF

The OV-5a and the OV-5b describe the operations that are normally conducted in the course of achieving a mission or a business goal. It describes operational activities (or tasks); Input/Output flows between activities, and to/from activities that are outside the scope of the Architectural Description.

The activities described in an OV-5a or OV-5b are standard Operational Activities that are mapped to corresponding capabilities in the CV-6 Capability to Operational Activities Mapping. Standard Operational Activities are those defined in doctrine, but which are not tailored to a specific system, i.e., they are generic enough to be used without closing off a range of possible solutions.

There are two ways to depict activity models:

  • OV-5a: The Activity Decomposition Tree shows activities depicted in a tree structure and is typically used to provide a navigation aid.
  • OV-5b: The Activity Model shows activities connected by Resource Flows; it supports the development of an OV-3 Operational Resource Flow Matrix.


The intended usage of the OV-5b includes:

  • Description of activities and workflows.
  • Requirements capture.
  • Definition of roles and responsibilities.
  • Support task analysis to determine training needs.
  • Problem space definition.
  • Operational planning.
  • Logistic support analysis.
  • Information flow analysis.

Product Description

The OV-5b describes Input/Output flows between activities, and to/from activities that are outside the scope of the Architectural Description.

Creating an Operational Activity Model

To create an Operational Activity Model:

  1. Click on Operational Activity Model in the Action Artifact area, and then select Create New Diagram.
  2. Type the diagram name and press Enter.
  3. A blank diagram is created and you can start constructing the view. Create the activity flows with OperationalActivityActions and other flow elements (e.g. Control Flows, Decision Nodes, etc).
