What it rests on
  • Tool wear is judged by ear
  • Rework is not counted anywhere
  • Deburring is done by whoever is free
What it could not settle
Published as contested, never recorded as a no.
  • none: every pair the room reached was settled
What was predicted to follow
Written after the map settled. Nobody voted on it.
  • Ask each customer for their inspection method and gauge list, and keep it with the drawing — expected: fewer parts come back once both sides measure them the same way — due 23 Jan 2027
What the room would do
Each action judged against each root cause, at three quarters of the votes cast.
