When a person is new to a machine, training often ends with a demonstration. Someone shows the setup, the new operator watches, and the shift starts.
Same machine, same drawing, different hands. Clamp order, stock approach, how the part is seated, how edges are deburred: each new operator runs a new version of the process. Evidence of how it runs may not arrive until final inspection, hours later, when parts already carry most of their cost.
The first piece is the first measurement of that process version. Without a check, the run becomes the test, and inspection, or the customer, becomes the feedback.
A better release point is a first-piece qualification gate. The operator measures against the requirement, records actual values, and a lead reviews them before the run continues. Measurement is part of the work, not someone else’s paperwork. If a reading is out of limit, the trainer can correct it early, before defects move downstream.
That is first-piece inspection doing training work: turning “qualified by watching” into “qualified by evidence.” The recorded first piece can become the standard the next hire trains from.
Deming’s point was that training belongs to the system. Leadership makes correct work achievable by building the check into the flow instead of assuming a demonstration was enough.
1factory records first-piece values against the requirement and revision. The first 10 hours of implementation are $500.
Better management question: when training ends, does qualification end with a signature or a recorded first piece?
