The approach I outline can explain and predict why the two Ts rotate, including at Toyota (Toyota going Taylor, or rather normative - rational).
I prefer not to base my experience on what Deming or anyone else wrote, but how their writing relates to real-life practice (though of course as a critic of Taylorism as represented by MBO and other Performance Evaluation rational schools, he is a welcome breath of fresh air).
Have you observed, preferably both as a participant and independent, Deming idealism in a functional real-life system? I have only seen a shift towards projectification and cultural hegemony.
