It’s amazing that, in this day and age, some manufacturers have not yet heard of “lean.” How are they surviving in today’s competitive market without it?

Today I’d like to talk about kaizen—specifically, the order for kaizen. The term has come to mean “continuous improvement,” but kaizen originally translates from Japanese as “change for better.” To help clarify this useful concept, I’ll present three different views for approaching kaizen: Taiichi Ohno’s, Shigeo Shingo’s, and Hiroyuki Hirano’s.
