Summary of Part III
Part III explains Toyota’s improvement kata, the fundamental approach for continuously improving and evolving throughout the organization. The improvement kata cannot be described in a few sentences, but now that it has been explained in Part III, it can be summarized with the simple diagram in Figure P3-3.
The improvement kata operates within an overall sense of long-term direction, which may represent an ideal state that might not ultimately be achievable. It is a direction giver. From day to day, however, the improvement kata often operates within the scope of a nearer and more specific target or need.
