What is the purpose for an interim action response to be returned within 24 hours after a corrective action is issued. I am trying to explain to my boss why it is important to get containment actions documented and returned within 24 hours. Documenting and sending back containment actions within 24 hours does not correct the problem, based on what my boss says. I have been taught that the 24 hour target time for interim is 1) painful for the supplier, and 2) gives the customer an insight to the activities occuring during this time period. Can someone tell me if that is correct.
