BOM Away from Hiller Associates

Yesterday, we began a series of articles at one of our media partners, www.ENGINEERING.com.  Instead, of focusing on Product Cost Management, we are focusing on another maddeningly difficult problem with critical implications to the Firm:  structuring the Bill of Material to promote ease of use… and re-use.  We will reprint the article below, and you can view the original here:

====================

A few months ago, unleaded client and asked me an interesting question.   That question was how does one reconcil the tension between specific parts or hardware vs. the functional use in the product of those parts.    This client was from a major fortune 500 company with a bill of material (BOM) containing thousands of parts on each product.  I was a bit taken aback, at first, by this question.  Although it is a very difficult question and subject, I assumed that most major companies were old hands at dealing with this tension.  I was wrong.

This reminded me that something that might seem old hat or common sense to one person, might be very interesting to another.  For example, when I graduated from the university and went to work for Ford Motor Company, I was taught that the Ford part numbering system.  Ford uses a system for parts that is an intelligent part numbering system, in which the part number makes it obvious which product programs , functional type of hardware, and what version of the part is being described

This system of numbering parts has been around for goodness knows how long.  It is no great secret in the auto industry.  I’m sure every person at Chrysler, GM, the foreign auto companies know the Ford system of numbering parts.  In fact, apparently , eBay even teaches us about the Ford part numbering system.  It’s very straightforward and makes complete sense.  As a young engineer, fresh out of school, who didn’t know any better, I assumed that every company had a similar intelligent part numbering system.  However, when I gained a little bit more experience and maturity, I realized that Ford’s ingenious but simple system was not so common sense at all throughout industry.  In fact, most companies I have met in manufacturing have nothing more than a sequential part numbering system that tells nothing about the part for which you were looking.

The point here is not for me to glorify the Ford part numbering system.  I’m sure there are companies with even better and more intelligent part numbering systems out there.  In fact, we don’t even have to go back into the horrors of the group technology fad in the late eighties or early nineties to know that!  No, my point is that relatively simple and logical ways of classifying (but not over classifying things!) on the BOM can really help us in our management of engineering parts and the product.

Therefore, in the next few weeks, I plan to post a series of articles that talk about these ways that we can view the bill of material and help ourselves and our company.  I look forward to hearing what other experts in the product life cycle management will have to say in comments.
