Al,
I would have to agree that most customers do not care. It has been this way for so long that most organization only do "inch deep, mile wide" thinking as opposed to "mile deep, inch wide". As Tom points out in his post, many problems are the fault of the Customer and not supplier oriented.
A classic example here at our facility is with our failure to get production level drawings to the supplier. This occurs about 10% of the time. The result is that our supplier produces tooling and parts to preproduction drawings. The effects are wrong parts with wrong features, production delays, and missed product launches (promise dates to our customer), and early obsolescence of remaining parts (because we reworked the wrong revision parts at cost to us and scrapped a few along the way). I am sure there are more costs associated. So now we are in a bind, need replacement, and must disrupt our supplier's (do a dare say, partner) production planning to have them quickly make tooling adjustments, acquire replacement raw material, interrupt another job running for another customer (whom they'll have to explain a delay to), change over, run parts and ship them to us at premium freight. Cost, cost, cost. I know I am not a 'mile deep' but the point is made.
In a System, we must rely on each component. In this way, we must view our relationships much differently than we have in the past. Hardships are felt across boundaries as are our successes. We are one team.
Additionally, the cost for moving production of a component from one supplier to another is costly. It is better to work out issues than it is to change sources (obviously, this approach will not work every time). Build rapport and loyalty. Work together with other components (customers and supplier) to reduce cost, minimize variation, and improve quality.
Well, just a Monday opening thought.
Regards,
Kevin
