Case Study 2 - SU22

Instructions

Please read this case study thoroughly and carefully.

You may brainstorm and collaborate with other classmates as long as you make sure that your final submission is unique and original. If I determine two or more submissions to be relatively identical, the students responsible of the submissions will receive a zero (0) on the assignment.

Always cite any outside material you might used and all the classmates you might have discussed with in preparing your submission. If I discover that outside help was used and not referenced, you will be reported to the Universitys authorities and expelled from the course. So be careful!

Templates

Templates are provided to help you complete the problems in this case study. While you are expected to determine which tool you should use, I do not want you to worry about most of the statistical calculations.

In the accompanying template, the changeable cells are highlighted in yellow. Some of the templates have additional instruction on to properly enter the data.

BUSA 5263 - Case Study 2 1 Case Study 2 Instead of a traditional case study, you will be asked to solve a series of problems. These problems focus on material covered in (Ch. 6 8). There is an accompanying excel file with the data needed to complete them. Please apply a good faith effort to complete this on your own. The difference in your submission and those of your other classmates should not only be the color and the font types used to type your document. I hope you understand. Templates are available in Blackboard to aide you in resolving these problems. Problem 1 Over the last year 752 drug doses were administered at the Goodhealth clinic. Quality is measured by the proper dosage as well as the correct drug. In two instances, the incorrect size of pill was given, and in one case, the wrong drug was given. At what sigma level is Goodhealths process? Problem 2 A gauge repeatability and reproducibility study was done at EngineBlader, Inc., which makes and repairs compressor blades for jet engines. The quality analyst collected the data for three operators, two trials, and ten parts, as found in the worksheet Ch08InstRsv.xlsx in the Instructor Reserve folder for this chapter. Analyze these data. The part specification is 4.7 0.1 inches. Calculate the process capability indexes for the parts. What does this tell you about the relative importance of part variation versus equipment variation and appraiser (operator) variation in assessing the gauging system? Problem 3 The cost data found in spreadsheet Ch08DataInsRsv.xlsx was taken from a paper manufacturing process at Oakton Paper Company by cost category. Prepare a spreadsheet and perform graphical analysis to show the significant few cost categories on which Oakton should concentrate. Based on your analysis make a recommendation for management on how they should act to improve quality. Problem 4 Data for Worldwide Metrology Repairs, Inc. cost of quality categories are found in the spreadsheet Ch08DataInsRsv.xlsx. Determine which categories contribute the most to the cost of quality at Worldwide. Show this, graphically, in a spreadsheet, and make a recommendation to management. Problem 5 Ellswater Hospital surveys all outgoing patients by means of a patient satisfaction questionnaire. A random sample of 350 surveys is taken each month. Control charts that monitor the proportion of BUSA 5263 - Case Study 2 2 unsatisfied patients for key questions are constructed and studied. Construct an np-chart for the data in the C08DataInsRsv.xlsx for Prob. 5, which represent responses to a question on satisfaction with hospital housekeeping services. Problem 6 Consider the sample data for defects per pizza in a new store being opened by Robs Pizza Palaces in the worksheet C08DataInsRsv.xlsx for Prob. 8-16. Construct a c-chart for these data. What does the chart show?
