The “zen” in Kaizen emphasizes the learn-by-doing aspect of improving production. This philosophy is focused in a different direction from the “command-and-control” improvement programs of the mid-twentieth century. Kaizen methodology includes making changes and looking at the results, then adjusting. Large-scale preplanning and extensive project scheduling are replaced by smaller experiments in improvement, which can be rapidly adapted as new improvements are suggested. Kaizen means improvement. Morever, Kaizen means ongoing improvement involving everyone, including both managers and workers. The Kaizen philosophy assumes that our way of life be it our working life, our social life, or our home life deserves to be constantly improved.
