Evaluation of raw materials suppliers
I am drafting some points on which I can evaluate my raw mat suppliers.
They supply me dry raw materials for animal feed production like fish meal , flour, wheat bran, wheat germe, fish oil, crude soya oil, shortening used oil, yeast.
I would evaluate them on basis of feed safety and hygiene, SQA, absence of infestattion, good traceability.
Any more help from you?
Thanks,
Rudra

Do you have a template for assesment ?

Basically you only need a table with 3-4 columns - date, size of individual incoming lot, whether accepted or rejected (or how many portions thereof rejected).
Then you can calculate an average rejection rate for an appropriate period, eg 1 month. The choice of time depends on factors like frequency of delivery, lot presentation (eg using sub-units or in bulk), lot size, sensitivity of item or its value.
The trickier part is in setting running evaluation criteria / corrective actions which again can depend on the precise application. For example, some people grade the suppliers, eg defect rates >10% = D = Fail, 5-10% = C, 2-5% = B, 0-2% = A. So maybe any incidence of D, or more than 2 successive scores of C triggers corrective action, eg a dialog with supplier to improve quality. Various permutations are possible.
(the idea is based on a very old chain sampling procedure associated with the American MIL standards).

This seems like a simplified approach.
Dear Bill Wheatley,
I guess it depends on what you mean by "simplified" ?. It's probably true that the designers of the MIL Std might be a little underwhelmed. But then again, rocket science applied to suppliers of used frying oil is possibly a little overkill also?
Nonetheless, I cheerfully admit to subscribing to KISS as far as possible if auditorially acceptable.
