Pareto Chart and Cost of Quality Report for a Manufacturing Company
The president of Mission Inc. has been concerned about the growth in costs over the last several years. The president asked the controller to perform an activity analysis to gain a better insight into these costs. The result of the activity analysis is summarized as follows:
Activities | Activity Cost |
Correcting invoice errors | $12,600 |
Disposing of incoming materials with poor quality | 10,080 |
Disposing of scrap | 37,800 |
Expediting late production | 32,760 |
Final inspection | 22,680 |
Inspecting incoming materials | 5,040 |
Inspecting work in process | 25,200 |
Preventive machine maintenance | 17,640 |
Producing product | 73,080 |
Responding to customer quality complaints | 15,120 |
Total | $252,000 |
The production process is complicated by quality problems, requiring the production manager to expedite production and dispose of scrap.
Required:
1. On paper or in a spreadsheet program, prepare a Pareto chart for each of the activities listed above. Answer the following:
What type of chart is a Pareto chart?

Which activity appears first, in order from left to right?

2. Classify the activities into prevention, appraisal, internal failure, external failure, and not costs of quality (producing product). Classify the activities into value-added and non-value-added activities.
Activity | Activity Cost | Cost of Quality Classification | Value-Added/ Non-Value-Added Classification | |
Correcting invoice errors | $12,600 | AppraisalExternal failureInternal failureNot costs of qualityPrevention | Non-value-addedValue-added | |
Disposing of incoming materials with poor quality | 10,080 | AppraisalExternal failureInternal failureNot costs of qualityPrevention | Non-value-addedValue-added | |

Total | $252,000 |
3. Use the activity cost information to determine the percentages of total costs that are prevention, appraisal, internal failure, external failure, and not costs of quality (producing product).
Quality Cost Classification | Activity Cost | Percent of Total Department Cost | ||
Prevention | $fill in the blank 23 | fill in the blank 24 % | ||
Appraisal | fill in the blank 25 | fill in the blank 26 % | ||
Internal failure | fill in the blank 27 | fill in the blank 28 % | ||
External failure | fill in the blank 29 | fill in the blank 30 % | ||
Not costs of quality | fill in the blank 31 | fill in the blank 32 % | ||
Total | $fill in the blank 33 | fill in the blank 34% |
4. Determine the percentages of total department costs that are value-added and non-value-added.
Activity Cost | Percent of Total Department Cost | |||
Value-added | $fill in the blank 35 | fill in the blank 36 % | ||
Non-value-added | fill in the blank 37 | fill in the blank 38 % | ||
Total | $fill in the blank 39 | fill in the blank 40 % |
5. The department has fill in the blank 41% of its total costs as non-value-added. Internal failure costs represent fill in the blank 42% of the total costs. This means there is significant opportunity for cost savings. External failure costs represent fill in the blank 43% of the total department costs.
