How is a Pareto chart used in quality control?
It ranks defect types so teams can focus investigation and corrective action on the most common problems.
Does it identify root cause?
No. It identifies priorities; other analysis is needed to determine causes.
What should the data represent?
Each category should count the same kind of observation over one defined production period.
