Change Management Failure Workflow

I would like to get some input on how best to handle a change that fails the implementation step. I went in and added a status of "Failed" within the Implementation stage. In the workflow we want a failed change to still go to the Review stage so we can figure out why it failed. At that point, I am not sure the best way to handle the change.

We want to change to be reviewed and then move to the Close stage but we want to the final status of the change to be "Failed". While I've got a "failed" status built for the Close stage, it will show the change as "Completed" if you select the "Complete" button even though the status is Failed. So do we just never complete out the Closed stage so that way the status remains "Failed" or is there some other recommendation that makes more sense?

Thanks,

Tammy
