Wheels are not identical products. Wheels from different manufacturers are different. That is called product differentiation. Manufacturers come out with new models on a regular basis. [ad hominem snipped]

Exactly. Every CD containing MS Office or Redhat Linux are identical, just like every Cooper Corba GTH tire is identical.Originally posted by Ilja Preuss:
Yes, but that variance doesn't come from the manufactoring process. You don't want every wheel being different. Once you designed a wheel for a specific purpose, the value lies in being able to reproduce without variance. (We software developers value this, too - we'd expect every CD with software of the same version to behave identically.)

A good question is never answered. It is not a bolt to be tightened into place but a seed to be planted and to bear more seed toward the hope of greening the landscape of the idea. John Ciardi
For example, virtually every Windows based software works exactly the same way with the same keystrokes invoking the same functions. When I drive my wife's car it takes me a little while to orient myself because the controls for the windshield wipers and the lights are in a different place.

I think what he is trying to say is that when we want to learn from other industries how to improve our own (the software development industry), looking at manufactoring processes won't help us much. We don't need to learn how to reliably replicate - we need to learn how to reliably innovate.
