It is impossible to improve any process until it is standardized. If the process is shifting from here to there, then any improvement will just be one more variation that is occasionally used and mostly ignored. One must standardize, and thus stabilize the process, before continuous improvement can be made.

Kaizen is like a hotbed that nurtures small and ongoing changes, while innovation is like magma that appears in abrupt eruptions from time to time

Control charts are one of the statistical tools for solving quality related problems.

Where there is no standard, there can be no improvement. For these reasons, standards are the basis for both maintenance and improvement

Kaizen means ongoing improvement involving everybody, without spending much money.
