For  this assignment, you will need to conduct an experiment then create  visuals that will be placed within a PowerPoint presentation to present  your findings. Your presentation should be easy to read and have a  consistent design theme throughout. Please view the

first four chapters in the following Lynda.com course on PowerPoint Essentials

before creating your presentation.

Read the following experimental variation scenario:

To  help you learn about measurement variation, try this experiential  learning exercise. (We are indebted to Alan Goodman, DuPont Company,  Wilmington, Delaware, for bringing this exercise to our attention.)

You  have started a new business providing height measurements of humans.  Your customers expect accurate and precise measurements. You offer two  methods of measurement: (1) a yardstick or a meter stick, and (2) a tape  measure. You need to test the two methods to evaluate their performance  and provide the results to your customers.

For this experiment you will need the following tools:

A yardstick or meter stick

A tape measurer

Access to an entrance door that is 6 feet or taller

A  group of 20 or more people (they do not have to be gathered at the same  time, but it should be 20 different people that participate).

You  will test Method 1 in this way: Identify a group of 20 or more people.  You will ask the group of 20 or more people to measure the height of the  entrance door that is approximately 6 feet or taller. Be sure that the  entrance door is the same for each member of the group. Each person will  measure the height of the door using the yardstick or the meterstick  and will silently report the measurement to you or to someone you have  designated as the data collector. You will then tabulate the data and  plot each measurement on a run or sequence chart. No deviation from the  prescribed method is allowed.

  • In  method 2, you may use the same, or a different, group of 20 or more  people and the same or a different entrance door. This time, the group  will use the tape measure in any way the group members desire. Again,  each person silently reports the measurement of the entrance door to you  or a designated data collector, and you will tabulate and plot each  data point.
  • You will then create a PowerPoint presentation that includes each of the following items:
  • Compare  the accuracy and precision of the two methods using graphical and  analytical methods. Which method was more accurate? Develop a flow chart  for each method in which you specify the key problems that might be  present. Develop the supplier, input, process steps, output, and  customer (SIPOC) model to analyze the process of both methods. This can  also be done in the flow chart. (Please reference these instructions on how to create a flow chart in Microsoft Word.) 

  • Analyze  the flow chart and SIPOC model to identify opportunity for improvement  (OFI). Next, categorize whether the OFI are caused by special causes or  common causes variations. Provide a rationale for your response. Which  method of measurement would you recommend? Why? Should different methods  be used under different circumstances? Consider the role of different  customer segments.
  • Discuss  the feelings the group(s) had when using the two methods. What were the  differences between the two sets of feelings? Are these differences  important?
