What is a quality tool?

Quality tools are techniques, methods, or instruments commonly used in quality management and process improvement to identify, analyze, and solve quality-related issues. These tools help organizations monitor processes, ensure consistent product or service quality, and drive continuous improvement. Examples include the Pareto chart, cause-and-effect diagram (Ishikawa or fishbone diagram), control charts, flowcharts, histograms, check sheets, and scatter diagrams. Quality tools are widely used in various industries, particularly in manufacturing, healthcare, and service sectors, to maintain high standards and optimize operations.
