Train the Station

A control plan only works if the operator can follow it. Write the work instruction for the station, release it at a revision, then watch each operator find a planted bad part before you sign them off.

Write the work instruction for the station first: one page, steps in order, a picture of the boundary sample and the reaction where the operator needs it. Release it at a revision letter and record the revision in every training record. Then prove each operator can do the job by having them find a planted bad part before you sign them off.

Weeks 5 and 6. The control plan only works if the operator at the station can follow it. Station 30 is trim and inspect, run on three shifts by six operators. The plan's checks all land on that station, so the work instruction is written for it first.

Write it for the person doing the job

One page, steps in order, one key point each, a picture of the boundary sample, and the reaction written where the operator needs it. The station's six steps:

  1. Load the part in the trim fixture.
  2. Trim the gate in one cut.
  3. Compare the snap hook to the boundary sample.
  4. Every 30 minutes, measure five consecutive pieces for hook height on the fixture and record them.
  5. Place good parts in the divider tote, one per pocket.
  6. If any check fails, stop and follow the reaction on the sheet.

Release it at a revision letter, here Rev A. Every training record names the revision it was trained to. A record that does not name one proves nothing when the instruction changes.

Train, then prove they can do it

A signature on a sheet shows someone sat through a briefing. It does not show they can do the job. Each of the six operators ran the station on five pieces, and one of the five was a planted short shot.

Five of the six operators found the planted piece and recorded it correctly. One passed it. That operator was retrained on the boundary sample and tested again, and found it. Six of six were then signed off on the skills matrix, with the date and Rev A.

The mistake to avoid

Training by handing out the instruction and collecting signatures. If nobody watched the operator find a bad part, nobody knows the control plan works.

ON THE FLOOR MONDAY
  • Pick one station and read its work instruction at the station.
  • Ask an operator to do the steps. Does the sheet match what they do?
  • Check every operator's training record names the current revision.
