Assembly Defect Pareto Chart

This Pareto chart helps a kettle assembly team see which defects deserve attention first. Loose lids and scratches dominate the recorded defects, while the cumulative line shows the share covered by each additional category. The chart can direct a root-cause review toward the few issues with the widest production impact. It does not prove the cause of any defect; it only organizes the observed counts for investigation.

FAQ

Domande frequenti

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.
