I read this more than twenty-five years ago, and it was quite impactful.
It helped ignite my thinking around bottlenecks and waste. It is very much a book from the 1980s, but that is part of its usefulness: it explains operational constraints through story rather than abstraction.
For many people, this was the book that explained ERP-adjacent thinking before they knew to call it that.
Personally, I later worked on multiple ERP, planning, and scheduling systems after reading it. That may have been incidental. But the book had already made the shape of those problems more legible.
