You don't see this kind of approach in large scale construction project with layers of contractors and subcontractors covering dozens of disciplines. You don't see this in car industry where they can do design, engineering, testing, factory tooling in 3 years. I think you do see it in construction and automotive assembly: the project is decomposed into small pieces and tackled by large numbers of specialists, who are individually regarded as interchangeable. Or when you say "this kind of approach" are you thinking of something else?
