Re: When to Close?
Effective implementatioon is when the issue is closed. Untill that point your customer is at risk for receiving parts with unacceptable condition identified.
Unacceptable condition- kids shirts scatterd on floor
Corrective action- told kids to pick up shirts with in this next minuit OR ELSE!
as any parrent can tell you C/A is not closed
No, it probably is not closable, not even effective. Just because you have one interim, or immediate action item to accomplish does not mean that you have gotten to the root cause and solved it. My kids might have their clothes picked up tonite before I get home from work, but you can bet your paycheck that within 24 to 48 hours, there will be clothes on the floor again. At my house, I figure that this corrective action will be able to be closed about the time my youngest turns 23 or so and they are all through college and living in their own homes
I even have a plan to accomplish that moving out. I'm selling my house and moving into an RV. (root cause of problem was discovered to be that in some sort of week moment I was overcome with the mistaken ideal that having children would be such a cool addition to our family. Kind of like seeing those cute puppies in the pet store. Eventually they grow up.
So, the long winded answer to your problem is that you can close individual action items as soon as you have implemented them and found them effective and satisfactory, but the CAR cannot be closed until you have 1) found the root cause, 2) made a plan to eliminate recurrence, 3) satisfactorily and effectively implemented the entire action plan.
