- I'm not disparaging skilled tradesmen, in fact I usually hold them
- in higher regard than most engineers. Engineers would benefit by
- *listening* to them more often. But hammering metal is a skilled
- trade, not engineering. Good engineers take production requirements
- into account in their designs, bad ones don't. Production engineers
- do time and motion, setup optimized assembly lines, and natter about
- workgroups and just in time subassembly deliveries. Those are important
- in some mass production facilities, but good design engineers make or
- break production at the very beginning of the development cycle. Ease
- of assembly and ease of field service have to be designed in from the
- very beginning of a product. Having design engineers apprentice on
- the shop floor for a few years *before* they get to design a product
- would do a world of good for our manufacturing sector. It certainly
- has for the Japanese and old school Germans.
