Review the chapter text about the Pareto rule and examine Figure 18-4. Note that the text
says Pareto diagrams are often drawn to reflect before and after results.
Assume that Figure 18-4 is the before diagram for the Billing department. Further assume
that the after results are as follows:
Activity Activity Code Number
Process Denied Bills PDB 12
Review with Supervisor RWS 10
Locate Documentation LD 6
Copy Documentation CD 5
1. Redo the Pareto diagram with the after results. (Use Figure 18-4 as a guide.)
2. Comment on the before and after results for the Billing department.
