First seven toolsIn the quality improvement movement in Japan in the latter half of the 20th century, the Japanese Union of Scientists and Engineers (JUSE) were influential in defining a set of basic tools that could be used for improving processes. These came to be known as the first seven tools. They are:
Despite some fancy-sounding names, they are mostly very simple and easy to use: the trick is in consistent and appropriate use, not intellectual gymnastics and elitist occasional usage. The tool that requires most thought and understanding is the Control Chart. A number of these tools are only usable when a significant amount of numerical data is available. For situations where the data is more qualitative there is a second set of seven tools defined (seven seems to be a magical quality number :-).
