The Operational Activity Model represents Operational Activity hierarchies. It must be created first.

To create an OV-5a diagram for Operational Activity hierarchies

  1. Create Operational Activities.
  2. Create or Reuse from OV-2 (recommended) Performers.
  3. Draw Is Capable of Performing relationship between them and Operational Activities.
  4. Draw Compositions (whole-part relationships) between Operational Activities if necessary.
