Generally commodity vendors items are not included unless they directly affect the quality of your end product.

Let's say that we buy them heat guns used to heat shrink tubing (covering ring terminals), gun's performance could affect product quality so this suppliers should be evaluated and re-evaluated, if everyone agrees, then How can achieve this task ?

Thanks.

I differentiate between distributors and subcontractors on our AVL and in our purchasing and supplier control procedure. I would evaluate a subcontractor on the quality of their product, along with on-time delivery, price, etc. For vendors - I monitor order accuracy, on-time delivery, price, etc. Only the manufacturer has control over the quality of the product.

If I usually buy a heat gun of a certain brand, and along comes a sales flyer offering a "comparable" brand name heat gun at a discounted price, I may buy the brand on sale. If that brand fails to perform comparably to the brand we usually use, how could we complain about the distributor? They gave me what I ordered. Wherever I buy a heat gun from in the future, I won't order that brand again.

If you've been buying the same brand for years, and all of a sudden receive one that is not in working order - all you can do is return it to the distributor for a replacement. The distributor then returns it to the manufacturer (or wholesaler) for credit.

I have had those suppliers on apprved suppliers lists in the past. We rated them on Price, Delivery, and Product Quality. 1-10 scales for each category with a minimum acceptable rating for each category and a minimum acceptable overall rating. Nobody ever balked at our ratings methods. We did have to explain what it took to get to a 5 or a 10, but you've got to do that anyway to make sure that all products/suppliers are being evaluated the same way.

Whether I buy a heat gun from J&L, Grainger, McMaster-Carr or Joe Shmoe that comes around with the truck-o-tools, I won't order that brand again.

I like this alternative to differenciate form subcontractors - suppliers and vendors. Thanks.

Vendor Rating System

I picked up a vendor rating scorecard from one of the threads . But my quality manager is asking from which BS Standard it is take.

IE Supplier Quality Performance = 0.6 x (Quality Rating) + 0.4 x (Delivery Rating)
= Performance Rating



Can you please help asap we have a meeting with the MD Tomorrow

:magic: :truce:

That may come from Juran's Quality Handbook. If I'm wrong somebody correct me, but I don't believe there is a standard for vendor rating. You are free to rate the vendor according to what ever works for you.

As far as I know, Al is correct. There is no 'standard' which defines how to rate a supplier (vendor). Each company decides how they want to rate suppliers.

I have attached 2 examples. One is a supplier rating flow chart and another is a supplier rating form. BUT - To repeat myself, there is no standard that I am aware of.

Here are some discussion threads where supplier ratings are discussed: Supplier Rating discussion threads.

You might also want to take a look at this Simple Supplier Evaluation form in the free files directory. Technically it's a supplier evaluation form, but look at what the supplier is evaluated on.

So - the most important part is the criteria you use to rate a supplier, such as on time delivery, number of nonconforming items you receives (or shipments with nonconforming items). How you decide to weigh each is, again, not from a standard. It is something that each company decieds as determined by their need(s), what is being supplied, etc.

Explain to your quality manager that there is no standard per se which specifies how to rate suppliers.

The form / example that you got here that you refer to is just one company's way of rating a supplier.
