A pareto chart or bar chart are used to identify which category (Customer Service Issues) are the highest. The pareto chart shown on the right can be made in excel.
The pareto that is shown on the right is for the timeframe starting July 8 through September 16. There are 4046 issues that were filed in Customer Service.
If you follow the beginning of the orange line in the center of the order bar to the y-axis on the right. You will notice that Wrong order received is @ 40% of the overall population. This seems to be a good opportunity for the team to dive deeper and see what is going on.
You can also make a bar chart with paper, pencil or marker. This is a quick and easy way the chart can be updated without printing out the chart each time. It is a bar chart because it will just contain the bars and not the y-axis for percentage .
