All true. NOBODY has or had any clue about the dynamics of JIT supply chains. If you are an engineer: the assumptions were that they were linear and time-invariant when in fact they are highly nonlinear and time-variant. NOBODY with an MBA (unless they are engineers first) has ANY CLUE about dynamical systems, Lyanpunov stability, differential equations, etc. that actually describe how JIT supply chains work when you vary volume greater than ~1%-5%. BTW the same can be said of financial networks, electronic bourses/markets and high frequency trading. Same problems. Same ignorance. Same risks nobody understands or sees.
