There is alot of area in the manufacturing company especially those running below than 2 sigma to produce part that we can say it is a 'acceptable' part. Acceptable part mean part that the specification (dimensional and cosmetic) may still can be accept by customer.
Customer (Quality Inspector) may accept that condition base on thier personnel judgement. What happend once that Quality Inspector resign? and end customer start to make complaint on the goods. Are they going to use the buffer stock? Are they going to accept your previous and current lot? Aha....??? Now the problem will return back to you..
I believe that we may sometimes or frequentlly do this to our customer. This acceptable part may generate because of lack of communication between external parties; suplier and customer, or internal parties ; interdepartment personnel, miss inspection, miss look, process change with out approval or notification, running without follow Standard Operation Procedure (SOP), lack of manpower training, and alot of thousand ceative reason.
In this issue, all of the parties must work together and make the unclear thing to be clear and ensure everybody get the same information.
There is no customer place any part order without drawing or dimensional specification. The best thing is, follow whatevet stated in the drawing / blue print. And as customer, don forget to put important information (no hiden information) in the drawing / blue print.
As a supplier, please ask whatever unclear information, get as much as you can information form customer, ask your capacity, either you can produce that part according your customer requirement before you start your mass production. If you has work on that field for couple of year, utilize your experience to help your company achieve the goal / objective.
As a employee, are you ready to make one step ahead to reduce your company risk? Ask your self...
