You've done a pretty detailed analysis of the company process.
So is the Production Engineer "Seisan Gijyutsu" focused on finding improvements for the Craftsmen to develop or does the Production Engineer "Seisan Gijyutsu" develop the improvements and teach them to the craftsmen?
The production engineer is there to optimize the production line - this is where Iso9000 and BS5750 really come into their own.
eg if i replace this machine tool with x% scrap/rework rate with a new one that has y% and the new machine costs Z$ million - how long does it take to payback.
I would suspect that the engineers theorise what can be done and produce a small scale demonstration and then the craftsmen take the concept and refine it into something that's reproducible at scale too.
