Hiiii,
We are implementing AS9100RevC, i am bit confusing about supplier performance. After registration at the initial stage we are evaluating suppliers and perodic evaluation(Once in two years audit). Is it necessary that we have to rate the supplier based on Quality and delivery.
This is my pet peve.
Please don't do an annual review of performance of suppliers. Its ridiculous. If you have a bad supplier you need to act NOW.
The standard requires that you have a method for the evaluation and selection of suppliers based on YOUR company's criteria. In general most companies select suppliers based on price, capability, capacity , etc. Sometimes location. The Aerospace stanrad requires that you do this for the part purchase. In other words you can't just issue a purchase order to ABC Compnay because they make other parts for you. You have to justify why ABC is the best supplier for the part you are trying to purchase.
Usually a form with you criteria which you fill out and then make a decision based on the data. ISO certification won't get you a good part.
The standard futher says that you must continue to evaluate a supplier one they are being used. As I said, the annual review is ridiculous. I always put in place a real time tracking system. The system is filled out by receiving for on-time. Quality goes to the data base and notes any quality issues in addition to issuing any CA. The database can be set up to record points and "red line" the supplier. BUT, it is purchasings responsibility to monitor suppliers and it is best if done real time. When a supplier misbehaves action should be taken immediately.
This is all that is required and any good business minded person would want to do this.
It's just common sense.
Please don't do a self survey. Its also useless.
The INTENT is that you choose the appropriate supplier based on criteria that will make sure the customer gets good parts, on-time and that you are aware and take action when a supplier shows signs of endangering your business and you customers product.
Good purchasing people are doing all the correct things. The Quality department just needas them to record it better and stop forcing old paradigms on purchasing.
Purchasing only needs to summarize the ongoing real time evaluation for management review.
The point is....its all about making money. Not putting in useless hoops to jump through to fake out the auditor.
