We've managed to leverage Service Desk for getting a change management setup to a point near using in production. But there are two big hurdles.
- For Standard or Pre-Approved Changes - need it to be a drop-down list of pre-populated requests that are preferably Normal requests that have been approved to become Standard.
- Need to require that at least one approver whether just one or many approvers are chosen is requester's manager. So maybe just a way to auto-populate manager of the person creating request and give option of additional approvers...all in one workflow step.
I can give any better explanation if needed, but these don't appear to be built-in features. Still seems that Service Desk isn't really there yet for change requests.
