Presents complex or abstract statistical information in a simple, visual format. The seven quality tools help monitor and control production processes, analyze and solve problems, generate ideas, and help make improvements. The seven tools include:
- cause-and-effect diagram (or ishikawa or fishbone): Identifies many possible causes for an effect or problem and sorts ideas into useful categories.
- check sheet: A structured, prepared form for collecting and analyzing data; a generic tool that can be adapted for a wide variety of purposes.
- control chart: A type of run chart used to study whether a process is predictable / capable and how it changes over time.
- histogram: The most commonly used bar graph for showing frequency distributions, or how often each different value in a set of data occurs; looks at the range of variation in a process.
- Pareto chart: Shows on a bar graph which factors are more significant.
- scatter diagram: Graphs pairs of numerical data, one variable on each axis, to look for a relationship.
- run chart: Shows process data trends over time.
- flowchart: Visually displays the steps of a process and how the people interact within it.
