My wife has worked in manufacturing for 20 years. It's very interesting to hear all the "technologies" that they have developed: six sigma, Kanban, lean manufacturing and all that. A lot of of that really feels like REAL engineering. Vs "sprint review" and "retrospective" crap we deal with in software.
Lean applies to software probably more than any other methodology in my opinion.
The simple practice of aggressively removing waste in all of your processes offers more benefit than anything else. The result of that is often closer to a much more simplified kanban system in my experience as well.
