Hartwell & Pryce Engineering controls torque tool TT-017 at its Brighouse works. This invented scenario assumes the task, capability and service requirements have been approved by the responsible people. The numbers are illustrative, not engineering instructions.
Establish the truthful starting point
The Owner prepares the issuing crib, return-review position and stations. Sarah, acting as Author, enters the approved tool identity and task requirements. James, acting as Reviewer, checks independently expected cases and activates the unchanged proved revision.
The Supervisor physically finds TT-017, confirms its good condition and crib position and records opening custody. A suitable service source is submitted and accepted through authorised human review for the relevant task scope. Neither reference activation nor a file upload alone establishes all these facts.
Check a bounded use
Sam chooses the station, TT-017 and Priya's active borrower contact. The approved task permits a two-hour use interval and a later return deadline. Sam checks the preview. Accepted required qualification must cover the whole two hours, not merely the moment of issue.
He confirms the actual physical handover and records it once. A borrower badge helped find Priya's contact; it did not authenticate her as the signed-in application user. The loan records Sam as the actor.
Receive damage truthfully
Priya returns the tool with visible damage. Sam identifies its exact current loan, selects Damaged and the actual return-review position, records the return context and confirms receipt. He does not mark it good just because damaged tools cannot be issued.
The loan ends as returned, while inspection and condition barriers remain. The Supervisor checks the physical tool and records the reviewed decision. If it needs service, the authorised service custody path preserves that separate handover and return.
Keep readiness separate
A later accepted service result does not automatically clear the damage hold or put TT-017 in the crib. The required condition and hold review must be recorded, then actual restow confirmed when current checks permit it.
A Viewer can later follow the original issue, damaged return and subsequent reviews in History. The status PDF is a snapshot of that recorded sequence. A new issue still requires a fresh borrower, task, interval and eligibility check, even if an earlier document looked satisfactory.
Hand over the unresolved work
Sam and the Supervisor hand over TT-017 as a returned but restricted asset, rather than describing it as ready. They retain the exact loan reference, damaged-return event, actual review position and any uncertain original command.
| Point to hand over | Expected position | Next responsibility |
|---|---|---|
| Operational loan | Returned only after the recorded return is confirmed | Sam checks the original return outcome; he does not record another return after a timeout. |
| Visible damage and return review | Restriction and review remain visible | Supervisor establishes the actual condition and records the specific decision. |
| Required service evidence | Submitted evidence remains pending until permitted review | A Supervisor with current service-review permission reviews the retained original, scope and dates. |
| Future crib availability | Not established by service acceptance alone | Resolve the relevant condition and holds, then record actual restow when allowed. |
If James holds Reviewer for reference approval but no Supervisor role and service-review permission, he cannot take over the service decision. The team arranges the correct authorised person while keeping TT-017 out of ordinary issue.
At the next shift, Priya's earlier borrower record and the completed loan remain historical facts. The next issuer selects the real next borrower and task, declares the intended use interval and obtains a fresh eligibility preview. They do not extend the earlier loan or use its old status PDF as authority for another handover.
