How Do You Choose The Best Supplier?

Posted December 18, 2012 1:50 PM by Milo

Guest post by Steve Staub, Made In Dayton Blog

Steve Posts on Made In Dayton Blog

We have enjoyed many of Steve's posts via Linked In, this one I just HAD. TO. SHARE.

I was contacted recently by a potential customer asking for our hourly shop rate. When I asked him why, he said it was so that he could compare our services against that of our competitors. I told him that our hourly rate doesn't really matter when looking at the overall cost of manufacturing a part and choosing the right supplier. He did not understand what I was talking about so I went on to explain it like this. Let's say that Company X has a new state of the art Whatzit machine and Company Z has a 10 year old Whatzit machine. Company X charges $ 100.00 per hour on their machine, Company Z charges $50.00 per hour on the machine that they have. Which company are you going to choose?

I'm guessing that you have decided to go with Company Z because they charge only $50.00 per hour. But, did you know that with technology improvements a new Whatzit machine is actually 50% faster than they were just 10 years ago? This actually makes the price the same between the two companies… or at least close. But what if the pricing wasn't the same? Let's say that two companies quoted production of a part and Company A came in around 10% cheaper than Company B. Do you automatically give the project to Company A? If you do, you're certainly not alone. Many companies do this all the time and the lowest price always wins. But is it really a lower price if you have a lot of rework? Is it truly a better price if the project is late? Here are some questions I like to ask to really find the lowest overall cost:

  • Does this company have a track record of on-time delivery?
  • How is their quality and what is their rejection rate?
  • Can they track my material and offer material certification?
  • How easy are they to deal with?
  • Will a real human answer the phone?
  • Are they convenient to get to or are they located in the middle of nowhere?
  • Are they ISO certified and do they have a Continuous Improvement plan?
  • Are they the newest kid on the block or are they an established, stable company with an Outside Board of Advisors?

All of these questions (and likely more) need to be answered to make sure that you are dealing with a reliable and reputable company that is going to provide you with a good value and be around to service you for years to come. I'm not saying this is the only way to evaluate a supplier. I'm just sharing some things to think about.

So… how do you choose?

The interesting thing about it, after a few years and taken a couple of knocks on pricing. I normally would ask (3) quotes and I no longer just look at the bottom dollar (normally), and the only time I do is when the RFQ on one is are more than 15% difference either way. That will shake me and thinking that there is something not correct with the cheaper RFQ.

I have felt that a tightly run shop, it is very difficult to under bid your competitor. To do any type of work, it requires time (Machine) and effort (skill) , and any established shop that has a solid history the quotes/work tend to be very competitive. How it does it does not matter the portion of either More Time/Less Effort or Less Time/More Effort.

I suspect you were talking to an Accountant.

They famously run businesses "efficiently" right up until the banks close the factory doors.

Sorry but the whole information aquisition + Header - is wrong !!

Yoy have to choose at least 2 Best Suppliers (better:3 !!)

The questionary is good for a new company !!-and questions asked are grotesque;

If they have ISO 9001 - it also answers material certification tracing

If they are in "Nowhere" - you could figure it for youself

"Will a real human answer the phone"..(?!?!),don't think that robots replaced humans

There is allways an opportunity to meet "the newest kid on the block" !!

For established suppliers for your Facility - you have all other answers collected by now

The most important key to work with "Best Suppliers"-is to "keep them alive"....

- by making a second pricing RFQ with the best price as a bench mark!!

- and if possible to divide quantity inbetween (you will see that price difference will be

quite low)

(of cousre that they have the quality and delivery you can depend on)

Very interesting subject. It is not only applicable to machining jobs but also to finished products. If we discuss about job work charges my comments are as under:-

1.It depends upon the type of job you would like to get machined. If it is simple turning job not requiring high accuracy then you can rely on small shop with simple lathe even old one. This shop will be cheaper and most competitive.

2.If you have accurate job to be done in large quantity,then you have to approach shop with CNC lathe.This shop will be costlier but you are assured of accuracy.

3. Of course there are many other factors as cited by you which are to be considered before selecting vendor.

As for as products are concerned there are various factors which need to be considered. These are as under:-

1.Quality of the product. Does it carry quality certifications?.

2.Reliability of the product and its mfr.

3. Does it conform to national/international specifications.

4. Past performance, is the brand name well known in the industry.

5.Service back up and availability of spares and interchangeability with original worn out parts.

6. Lastly price quoted by the distributer, is it competitive?. It may be expensive than imported China make, but it will be preferred as being long lasting reliable product.

You are talking Cost of Poor Quality issues. Is hourly rate the only thing the customer wanted to know? I have problems with people who act as though a proper decision can be made with only one data point.
