Some quality tools to analyze defects include Pareto analysis, Fishbone diagram, 5 Whys, Scatter diagram, and Control charts.

• Pareto analysis helps identify the most significant causes of defects by focusing on the vital few versus the trivial many.

• Fishbone diagram (Ishikawa diagram) helps visualize all possible causes of a problem to identify root causes.

• 5 Whys technique involves asking 'why' multiple times to get to the root cause of a defect.
