Corrective Action Priority
I will have to agree with Claes on this subject.
Remember that the first phase of corrective action is to identify the problem then to contain it.
Once you contain the problem then develop a initial corrective action based on the evidence that is in front of you.
The initial corrective action should be detailed enough to prevent any catastrophic event from happening. (Speaking about a product rejection, safety concerns, and/or a financial event)
Then develop a root cause and corrective action.
Remeber that corrective action takes time and is a step by step process.
