Not every NCR needs a corrective action; every NCR needs the decision, recorded as Yes or No on the log. Correction (what is done with the product) is always required; corrective action (removing the cause) is required when the risk or the pattern calls for it.
| Open a corrective action when ... | Correction only is usually enough when ... |
|---|---|
| The customer found it, or it may have shipped | It was found in-house, one-off, contained to one lot |
| It touches a safety-related or key characteristic | No safety-related or key characteristic is involved |
| It has happened before, on this or a similar part, process or supplier | There is no history of the same failure mode |
| It needed a use-as-is or repair, so the customer is involved | The cause is clear, confirmed and already removed |
| It points to a weakness in a process or the system | The trend review (F09) shows no pattern |
When the answer is Yes, the corrective action runs in the CAPA Command Kit: investigate, act, and prove it worked with the effectiveness verification worksheet (B08). Link the CAPA reference on the NCR line. When the same failure mode returns after a CAPA was closed, reopen that CAPA or open a new one that says why the first did not hold; the repeat register (B10) connects them.
