A workflow is a set of stages, such as Draft, Review, Approval, and Deploy. Each stage has a list of possible actions that move the workflow to a new stage. For example, the Review stage might have an action labeled Approve that moves the workflow from the Review stage to the Approval stage. The Review stage might also have an action labeled Deny that moves the workflow back to the Draft stage. The creator of the policy workflow template can create complex graphs that accurately model real-world practices.
Policy workflow is optional; you can create a policy without a workflow and you can add workflow to an existing policy.
