seven basic tools of quality
the designation arose in postwar japan, inspired by the seven famous weapons of benkei. it was possibly introduced by kaoru ishikawa who in turn was influenced by a series of lectures w. edwards deming had given to japanese engineers and scientists in 1950. at that time, companies that had set about training their workforces in statistical quality control found that the complexity of the subject intimidated most of their workers and scaled back training to focus primarily on simpler methods which suffice for most quality-related issues. the project management institute references the seven basic tools in "a guide to the project management body of knowledge" as an example of a set of general tools useful for planning or controlling project quality.
