I received my black belt certification from from AlliedSignal’s Engineered Materials division in 1995 as part of the “first wave” of black belt training (though AS called it “Process Improvement Masters”). The Mikel Harry “cartoon book” was mostly philosophy, really a collection of powerpoint slides. Useful concepts, but not really methodology. The detailed process improvement model was all Steve Zinkgraf’s, along with all the training material & methodology. The 5 weeks training was rougly 2 days Mikel Harry, 23 days Steve Zinkgraf.
