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.

Under the lean system, any tools which are required for solving problems are used.

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

I have a theory that among the large Western companies (mostly American) the higher an executive is promoted, the more wisdom is lost and by the time he or she reaches the top becomes a complete idiot. Certainly they do not deserve the outrageous salary.

I believe that management should focus on two particular areas. One is Gemba (shop floor) and the other is customer (not the shareholder).

I am beginning to see a large-scale introduction of various management tools, philosophies and practices in the service sectors and have a high hope that it will become a global trend.
