Delivery Complaint Pareto Chart
This Pareto chart ranks delivery complaints reported during April. Late deliveries create the biggest share, followed by damaged parcels and incorrect addresses. The cumulative percentage line shows how much of the complaint volume can be addressed by focusing on the first few reasons. It gives an operations team a defensible starting order for improvement work, while individual case records supply the detail needed to investigate each issue.
