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

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.

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.

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.

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

There are various non-statistical tools that have been typically developed by lean companies, notably by Toyota for minimizing variability in production, such as standardization, introduction of takt time, synchronization, shortening the total production lead time which I am fond of referring to as non statistical tools.
