No, your corrective action is taken to prevent reoccurrence of the problem; it is part of the corrective action process. In order to be considered preventive action you must be preventing a problem from occurring in the first place. One good place to determine preventive action is during management review, when you review data from the QMS. You can look at that data to see what problems might occur in the future, and take action to prevent them from occurring. You might also find opportunities for preventive action by reviewing corrective actions to see if the information shows you other problems that might occur, and take action to prevent them.

This requirement is found in Customer Related Processes; these are “implicit” requirements. What do you know about your product that the customer does not need to specify, or may not even know themselves? You know the intended use of your product, and are the expert on the product. If a customer in a luggage shop requests “Carry on Luggage”, they may not know what the acceptable size is to be able to carry on the bag. But the company that sells their bag as “Carry on Luggage” should know what the restrictions are, and meet those restrictions even though the customer did not know the size they needed.

The most common aspects of performance that are measured are quality, service and price. What can you put goals and numbers to that will tell you how the supplier is performing in each of these areas? Decide what the most critical aspects are to you, is it an item that you can get from a number of different suppliers? Is price, or on-time delivery the deciding factor? Or is it an item or material that can vary in quality and will affect the quality of your product? In this case, the supplier with the most consistent quality may be the best source, regardless of the price. Measure what is most important about what is being supplied.
