Production workflow and shop travelers · Lesson 4 of 4

Production workflow and shop travelers: defects, verification and case study

The defects of a workflow rather than of the metal, a historical case of traveler sign-offs out of order and how it was corrected, and the evidence that shows a job was built as approved.

You will be able to: Diagnose a workflow defect from the record, choose a corrective action, and document the evidence a reviewer needs.

Slide 1 of 10

Defects of the workflow

These start in the record, not in the metal:

An old revision bent instead of the approved one
A step signed while an earlier one is blank
Painted side formed the wrong way
A rush flagged that nobody chose (AFS's system refuses one)
Damage in staging: dents, condensation, film left on
