Certainty, not speed
Production planning depends on knowing that a given part is where the sequence expects it to be. When that answer comes from a spreadsheet updated at shift change, planners work from a picture that is several hours old — and the audit trail has to be reconstructed after the fact from separate systems.
Tool control carries a different weight. In aerospace it is a safety control, not a convenience: a tool that does not come back is a tool that may still be inside something that flies. The weakest link in that control is a person remembering to write something down under time pressure.
