The 7 Quality Tools are simple but effective methods used by organizations to identify, analyze, and solve problems. They include: 1. Cause-and-Effect Diagram (Ishikawa) – visualizes possible causes of a problem. 2. Check Sheet – a table to systematically collect data. 3. Control Chart – tracks process performance over time to spot variations. 4. Histogram – shows data distribution to identify patterns. 5. Pareto Chart – highlights the most common issues using the 80/20 rule. 6. Scatter Diagram – examines relationships between two variables. 7. Flowchart – diagrams steps in a process for clarity and improvement. These tools support quality and continuous improvement.
