Objective: You recommend using a design of experiments approach to hopefully realize a breakthrough improvement. The team brainstorms a long list of possible reasons why the average resolution time is so long. From that list, the team has reduced it down to five factors they want to include in an experiment. They do not suspect any interactions, so they conclude a resolution III will be adequate. They refer to the resolution matrix (in Analyzing Fractional Factorial Designs lecture and the online textbook) and they find they can learn about the effects of those five factors in as little as eight experiments. Instructions for you: Construct an main effects plot for all five of the factors. We will do the first one for you as an example: Take an average of the response time minutes (y) when "staff size" was at (-). Then, do the same thing for when the results (y) when "staff size" was at (1). When at (-1) When at (+1) 7 9 28 25 Average 26 6 16.75 8 28 17.50 Data: The factors for the experiment were: A B C D E - level 8 FIFO In person Product A BHD Staff size Order of responding Method of responding Tracking software Operating system + level 16 By priority Via web Product B JK-7 The design below was taken from Minitab. There are other software packages that provide the same information. There can also be found in Design of Experiments textbooks.

To send each assignment to your instructor: Click-and-hold the LEFT mouse button at the TOP-LEFT corner of the peach-colored box, then while holding down on that button, drag to the LOWER-RIGHT corner of the box. This will highlight the entire peach-colored box. Release the mouse button. Do a CTRL-C. This will copy what has been highlighted. Go to your Villanova website and follow this sequence: 1. COURSE MENU 2. CLASS ROSTER 3. Click on your instructor's email envelope icon 4. Type "Check My Work - DOE" in the SUBJECT box. 5. Click once inside of the message box 6. Do a CTRL-V. This will paste your deliverable into this box. Don't be concerned if after you paste it, the appearance of the text is out of alignment. It will straighten out after you hit SEND. 7. SEND Check your SENT ITEMS folder afterward to see how it straightened out. Please 'hand-in' your assignments throughout the course. DO NOT SAVE THEM FOR THE END.
