Shift Handoff: Hold the First Piece Until It Is Accepted
Hold the first piece after a shift handoff until a named person compares it with the approved sample, file revision, material, and inspection rule.
A production machine does not solve the human gap between shifts. The incoming first piece is where material, file, fixture state, and acceptance ownership can be compared before quantity resumes. Demand source.
What the outgoing operator hands over
Record active file revision, material lot, fixture state, completed count, open exceptions, and the last accepted sample. A verbal 'same as before' is not enough when a shift changes.
First-piece hold
The incoming operator labels and isolates the first piece. A named reviewer compares dimensions, orientation, visible quality, and identity with the approved sample and record. It stays outside finished inventory until signed off.
Stop and release boundaries
A mismatch, unexplained machine behavior, missing sample, or uncertain material keeps the run stopped. Acceptance applies only to the documented setup and does not certify all future pieces. This is a shop-authored handoff method, not an automated X1S Pro function.
Evidence record for shift handoff
| Decision point | Evidence to keep | Hold condition |
|---|---|---|
| Handoff | outgoing and incoming names | record unresolved issues |
| First piece | isolated and labeled | do not merge with finished stock |
| Comparison | approved sample and file | stop on any mismatch |
| Release | named acceptance time | limit to exact condition |
Release rule for shift handoff
Resume quantity only after the incoming first piece is isolated, compared with the approved sample and record, and formally accepted by the named reviewer with no unresolved handoff issue.

Buyer questions about shift handoff
Who should approve the first piece?
A named production owner or reviewer with the approved sample and acceptance rule.
Can the prior shift's last piece replace it?
No. The incoming first piece verifies the handoff state.
Does this procedure certify product quality?
No. It releases only the documented condition and is not certification.
