Question on the CA and PA,
SOME Time i should reply 8D to customer, but i have some confesion on the CA AND PA,
eg.
cosmetic problem, cause by operaor handlding error so it means
training operator is the corrective action , what is the preventive action? revise document WI ?
CA AND PA or CAPA are two methods of continual improvement.
There is no need to think of a PA after a CA for a noticed non conformance, in your case the cosmetic problem via the 8D to customer. You should rather work on how effective your CA has been in further eliminating such a defect. So revising document and any other sure steps that you take are the CA after finding the root cause of the problem
This learning can be such, that when you have an other cosmetic inspection requirement, you apply this and before hand prevent such cosmetic problem from surfacing. When you are so aware that you are applying the learning of an earlier corrective action, you are doing a preventive action and how effective this is for this new situation will again depend upon its effectiveness monitoring.
In both the cases you are continualy improving.
Logic: Once you have a problem and detect the root cause of it and take actions to eliminate it (CA) you will perform so smartly that the same problem due to that cause will not recur again in the future (PA)
I propose to put PA like these: Operaotr selfcheck and make a pen mark on the degated position, ......
or Put N/A
It's still a CA because you are taking action after a nonconformity has occurred. Furthermore, why it ("Operator self check and make a pen mark on the degated position,...") shouldn't be included in the WI that you proposed as CA?
As indicated by other Covers, Preventive Actions are those action that actually prevent a nonconformity.
Agree but the CA too does the same thing, i.e. prevent a nonconformity. The actual difference between the two is that of terminology - recurring and occurring.
For my case is cosmetic defected, easy to identified the cause and CA,
The root cause is the operator poor workmanship when use knife cutting the gate
CA: educate and training the operate the knife when degating by the revise WI
I propose to put PA like these: Operaotr selfcheck and make a pen mark on the degated position, ......
or Put N/A
