The Seven Basic Tools of Quality is a designation given to a fixed set of graphical techniques identified as being most helpful in troubleshooting issues related to quality.[1] They are called basic because they are suitable for people with little formal training in statistics and because they can be used to solve the vast majority of quality-related issues.[2]
The seven tools are:
Cause-and-effect diagram (also known as the "fishbone" or Ishikawa diagram)
Check sheet
Control chart
Histogram
Pareto chart
Scatter diagram
Stratification (alternately, flow chart or run chart)
