- To understand why a policy's owner is on the first approval step
Requiring policy owner approval on the first step allows the user assigned as the Owner to be notified via email anytime a policy has been edited since when the workflow is restarted the owner is the first approver. Without being listed as an Approver on step one, they are not notified of edits that have been made. By having the Owner on a step (mainly the first one) it allows for collaboration since the Owner controls if the workflow will advance and they can invite collaborators to get their input.
Another reason to have the Owner required on the final step one is to act in a gatekeeper role to ensure new edits made do not advance to other approvers until the owner reviews them.
Also the Owner checkbox could be enabled on the final step of a workflow to ensure that education, training etc. occurs before a document is finalized to be made active.
