Multi-stage maintenance request workflow with four sequential approval phases: requestor submission, direct manager review with optional bypass, maintenance department head validation, and final administration confirmation. The process routes requests through decision gates at each phase, with rejection paths that close tickets and approval paths that advance to the next stage. This structured workflow ensures proper authorization hierarchy and documentation of maintenance work completion.
