Mistakes and fixes

Preserve the original decision, the proposed remedy, the approval and the verification as separate records. Do not erase an earlier decision because a later one replaces it. Keep both, and say which one is current.

• Observation

  What was expected, what the record actually shows, and what is still unknown. Do not assign blame from an incomplete record.

• Proposed remedy

  A suggestion for what to change. A suggestion is not the change.

• Approval

  A person agrees to that remedy, or does not. The original decision stays visible either way.

• Verification

  A later check of what changed. Until that check exists, the remedy is not verified.
