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

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.

All of management's efforts for Kaizen boil down to two words: customer satisfaction.

The standard is not writ on the stone. The definition of the standard is that it is the best way to do the job for now. It should be regarded as a next step to make further improvement.

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

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.

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.
