It should have a quick end date, or shouldn't it?
No, quickies are, for the most part, not satisfying...
The time needed for the "once-and-for-all-put-to-rest" corrective action will have to be commensurate with the complexity of the issue and the nature of true corrective action. Much better to have a
monitored, gradual, "slow" but sure corrective action than a fast one that just turns into a band-aid.
Generally, 30 days out is about the limit that most of my customers want to see for the full CA/PA cycle.
And,
sometimes, that means that you are pretending to perform corrective action and they, your clients, are pretending to perform supplier oversight. Some problems will demand a thorough, time-consuming investigation. Some corrective actions might demand the procurement of capital equipment, something that has budgetary implications, not solvable in 30 days. As long as artificial deadlines are present, we will end up with band-aids, recurring problems.
We must not forget that, in addition to corrective action, correction and containment are also part of the process to address nonconforming products. Sometimes, containment has to be in place for a while, until true corrective action is in place.
