Kaizen – Continuous, incremental improvements of an activity to create more value with less waste.
A Japanese term meaning continual improvement involving everyone. Said by some, to be one of the most important concepts in "Japanese management", it is working each and every day to make improvements in the processes of the organization. Such incremental, but continuous improvement may reap great gains over time. It is contrasted with the western world's pattern of relying on major "breakthrough" to gain needed improvement. The term was used by Masakai Imai.
