I’d love to know more about what drove the mismatch of hiring unskilled labour for the unproven production line. Or rather, what went into the belief that the production line concept would cover for a lack of technical skill.

If lesson 2 was, “we should have taken the short-term more painful and expensive path of hiring experienced leaders for each trade or station” then that seems to suggest there were no experts.

So then how was the line designed and tested? Who were the people who built the first few houses before the unskilled workers were brought in? Who was training them? Where did those trainers go? How were the founders so confident in the absence of any trade leaders?

I suspect I am misunderstanding the situation, and that there were skilled experts who know how to build houses, but they weren’t appropriate to be actual builders for long?
