In some ways that attitude seemed admirable, but ultimately it didn't help the company win or keep consistent business. You'd have gaggles of smart people building custom prototypes but nothing scaled up. The customers couldn't see the vision of scaling their production there, or just saw that they could get better pricing going to factory which had already invested in the right special-purpose machinery.
That's what a factory is to me - ideally reconfigurable, but a place with capital investment for production. It's good to show kids what's behind the curtain but don't get it mixed up with a prototype shop.
