After completing the research needed for a complete request and sending it off for approval, you may want to update the status to "Pending". This reflects the change from actively working on a request to having sent it out and currently waiting for a response.

If the request is approved, it would move into the Contract workflow when the user "Converts to Contract". If the request is not approved or is otherwise ended, the user should change the status to one of the last three status choices.
