I used to work as a SW developer for an assembly line. Anecdotally, "my" "line workers" were very good at micro optimizations s.a where to place tools, when to duplicate stands, what order of operations makes more sense, alert when a material/part quantity drops. I was occasionally replacing one of them to QA a SW tool, and was pretty slow and clumsy comparing to them. I'd say overall their resourcefulness or "practical engineering" did some 1-5% impact on throughput.
