• Pareto analysis ----- which are the big problems?
• Cause and effect diagrams ----- what causes the problems?
• Stratification (SIPOC) ----- how is the data made up?
• Check sheets ----- how often it occurs or is done?
• Histograms ----- what do overall variations look like?
• Scatter charts ----- what are the relationships between factors?
• Control charts ----- which variations to control and how?
