Kaoru Ishikawa

“As much as 95% of quality related problems in the

factory can be solved with seven fundamental quantitative tools.”

In the 1950s, Edward Deming emphasized basic tools for quality improvement. Inspired by Deming’s lectures in Japan, Kaoru Ishikawa is attributed with further defining Deming’s basic tools into seven specific tools:

Anything Else Missing?


Problem SolvingTools Personal

Attributes

Leadership

Structure


The most important seven “tools” are really not tools at all, they are personal attributes:

• Persistence• Courage• Honesty• Persuasiveness• Curiosity• Patience• Sincerity

In the absence of these attributes, the 7 tools are not much help.
