Hello, thank you for taking my question.
We are a small aerospace distributor that basically uses hundreds of suppliers in any given year. Currently, all suppliers with 3 or more shipments are rated in three categories, On time delivery, Quality of Product, and Ease of doing business. These individual scores are weighted and totaled the resulting percentage is turned into a "Quality Rating" (100 -97= Excellent; 96-92 Very Good...and so on). Since we use so many different suppliers, the Quality Rating is cumulative and includes all shipments ever made by that supplier since to do otherwise it might take years for one supplier to accumulate enough shipments to get an accurate evaluation.
At a recent surveillance audit for 9120A, an Opportunity for Improvement was given to simplify our rating system and only use shipments from a supplier occurring in say, the past 6 months in our evaluations. I was told that no one uses cumulative shipments beyond that and that using every shipment ever made by that supplier was not appropriate. I contend, however, that because we sometimes don't use a supplier again for much more than 6 months, it would be very difficult to get an accurate rating on any one supplier.
So, I am confused on how to proceed. The system I use seems to work for us and I hesitate to change it however, given that Opportunity for Improvement I feel that I must at least try.
I would appreciate any thoughts on this issue. Thank you.
