A finished unit fails test, is stripped, gets a replacement component and passes on the second attempt. What has to happen to its genealogy record?

Answer

Short answer

The record is an append-only history, so the replacement adds an install event and a removal event rather than editing the bill of material, and both test results survive.

Likely follow-ups

  • The removed component is found to be good and goes back into stock. What must the record say about it?
  • A second unit is repaired using a component pulled from a third unit. Trace that for me.
  • How do you stop a bill-of-material change six months later from rewriting what this unit was built from?
  • The rework happens off-line at a repair bench with no station terminal. How does the record get made?
