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 $21,150
Disposing of incoming materials with poor quality 16,920
Disposing of scrap 59,220
Expediting late production 50,760
Final inspection 42,300
Inspecting incoming materials 8,460
Inspecting work in process 46,530
Preventive machine maintenance 29,610
Producing product 122,670
Responding to customer quality complaints 25,380
Total $423,000

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? Bar chart

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

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 $21,150 External failure Non-value-added
Disposing of incoming materials with poor quality 16,920 Internal failure Non-value-added
Disposing of scrap 59,220 Internal failure Non-value-added
Expediting late production 50,760 Internal failure Non-value-added
Final inspection 42,300 Appraisal Value-added
Inspecting incoming materials 8,460 Appraisal Value-added
Inspecting work in process 46,530 Appraisal Value-added
Preventive machine maintenance 29,610 Prevention Value-added
Producing product 122,670 Not costs of quality Value-added
Responding to customer quality complaints 25,380 External failure Non-value-added
Total $423,000

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.
