OV-5a – Operational Activity Decomposition Tree

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-5a 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-5 Operational Activity Decomposition Tree helps provide an overall picture of the activities involved and a quick reference for navigating the OV-5b, Operational Activity Model.

Creating an Operational Activity Decomposition Tree

To create an Operational Activity Decomposition Tree:

  1. Click on Operational Activity Decomposition Tree 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 OperationalActivities and/or StandardOperationalActivities through the tools under the diagram toolbar.

Optional actions:

Reuse OperationalPerformers (recommended) through dragging and dropping them from the Model Explorer, and traces the OperationalPerformers to the OperationalActivities using the IsCapableToPerform connector.
