Handbooks: KitProof

Worked example: quantities, serials and an exception

Follow a plausible kit without converting missing evidence into verified scans.

Review edition · 25 October 2026 · For Author, Reviewer, Supervisor, Operator, Viewer

On this page

Hartwell & Pryce Engineering prepares actuator service kits for job HP-6452. Each kit needs four approved washers, one bracket and one serialised controller. This invented scenario assumes those requirements and alternatives have been approved in your configuration; it does not supply engineering authority for real parts.

Prepare two individual kits

Sarah, acting as Author, defines per-kit quantities and exact component aliases. The controller requires a serial and cannot use manual quantity. The bracket has an approved alternative requiring Supervisor approval. Independent examples state complete requirements, including a missing-option case that must block.

James reviews the intended requirements and proof as Reviewer before activating the configuration. The Supervisor imports a line for two units. KitProof creates two kits, each needing four washers, one bracket and one controller. The aggregate eight washers help preparation but do not verify either kit.

Record the first kit

Sam chooses the checking station and claims the first kit. He scans the washers in physical order, checking each accepted answer. He scans the controller and records its actual serial in the separate prompt. A scan of the controller barcode as its serial is refused and does not count the item.

The available bracket is the approved alternative. Its first scan waits for approval and counts nothing. The Supervisor checks and approves the exact request. Sam refreshes and scans it again while the approval is valid. That release-permitted alternative can still form part of a Verified result.

Keep an exception visible

For the second kit, suppose one permitted nonserialised requirement cannot supply its ordinary scan evidence and its frozen policy explicitly allows a manual-count request. Sam states the quantity and physical basis. The Supervisor decides from the actual kit.

If approved, the disposition can satisfy the allowed outstanding quantity, but the final result is Completed with exceptions. No missing scan or serial allocation is invented. If policy does not permit that exception, the kit must remain unfinished or receive another authorised disposition.

Read the outcome honestly

The Viewer opens both attempts and retains their different results. The evidence identifies scans, alternative approval and any exception separately. Neither the prepared requirement list nor a printed kit reference is evidence that the physical contents were checked. A later source change requires its own review and a fresh check where the new revision demands it.

Hand over the unresolved work

Suppose Sam's shift ends while the second kit's manual-count request is waiting. He keeps the kit physically separate from the first kit and hands over its exact KP1: reference and attempt. Accepted controller serial evidence belongs to that kit; it must not be moved to the first kit or entered again merely to reassure the next operator.

Point to hand over Expected position Next responsibility
First kit Verified only after its permitted alternative is rescanned and all requirements complete Viewer reads that kit's retained evidence.
Second kit's outstanding quantity Still outstanding while the request awaits decision Supervisor reviews the exact manual-count request and physical basis.
Change of operator Ordinary pause or explicit Supervisor takeover, as current ownership requires Receiving Operator selects the station and claims the correct attempt before continuing.
Permitted manual-count disposition Completed with exceptions when all remaining requirements are satisfied Supervisor and Viewer retain the exception alongside the final result.

If the answer to Sam's last scan is uncertain, he uses Check the last scan before handing over a supposedly accepted quantity. The page has no persistent offline scan queue. If its pending context cannot be recovered, preserve the kit and accepted-history position for supervised investigation rather than estimating which scans counted.

Priya compares the current outstanding list with the actual kit before resuming. An expired alternative approval requires the permitted current decision and rescan path; yesterday's approval or a printed requirement list is insufficient. This handover preserves the two kits' distinct outcomes and does not turn the second kit's exception into ordinary part or serial evidence.
