In the event of a non-conformity, there are 3 possible actions to develop
Stop the non-conformity from continuing to occur! Stop the damage! Warn people! Do a recall! (examples of what can be done. You are not acting on the non-conformity, you are acting on the process or on the consequences)
Then comes correction. Correction is about eliminating the non-conformity (examples of what can be done are: segregate and repair; segregate and dispose of; segregate and downgrade; segregate and ask permission to send the product or accept the service as such – what is also called as a concession). Confirming that the correction was done
Then, if the nonconformity is serious or is systematic, comes the corrective action. Collect more information about the symptoms of the problem, investigate the cause, design a solution, implement the solution and do the follow-up to check the effectiveness
Action 1 is not always possible or necessary to develop.
Action 2 is always done.
Action 3 is done when the non-conformity is serious or systematic.
