1. Analyze the cost data in the Excel workbook Ch03Data.xlsx for the Costbusters Company. What percent of sales are represented by each category of cost for each product? What are the dollar costs for each cost of quality category, by product? How might this information be used to help define a Six Sigma project?
2. Prepare a pie chart showing the different quality cost categories and percentages for the Great Press Printing Company. See the data in the Excel workbook C03Data.xlsx. How might this information be used to help define a Six Sigma project?
4. Puragua Corporation makes water meters that are sold to contractors and municipal water departments. Analyze their quality costs, group them into the four standard quality cost categories, and prepare a Pareto chart showing the company’s quality costs that were incurred over the past year (use data
in the worksheet Prob03-04 in the Excel workbook Ch03Data.xlsx on the Student Companion website). How might this information be used to help define a Six Sigma project?

the Student Companion website and prepare a memo to management.
