Rather than trying to add anything to his comments, read his own words here and in the linked article.
“Another common reason TPS implementations fail is that managers try to implement individual elements instead of the entire TPS approach. Since the elements of TPS are integrated and interdependent, any attempt to implement TPS only partially is bound to produce very unsatisfactory results.
For TPS to work effectively, it needs to be adopted in its entirety, not piecemeal. Each element of TPS will only fully blossom if grown in an environment that contains and nourishes the philosophies and managerial practices needed to support it. I liken this to a greenhouse, where just the right combination of soil, light, temperature, humidity, water and nutrients allow plants to grow and flourish. If any one of these elements is removed, the plants will weaken and eventually die.”
