To set up your experimental design, first define three factors for the project: NumQC, NumRepair, and NumService to represent the number of workers at each of the three stations. See Chapter 5: Experiments, for more details about factors. To define the factors, first right-click the project name in the project window and select Factors to open the Factor Creation dialog box. Also define seven responses for the project by right-clicking the project name again and selecting Responses to open the Response Creation dialog box. Figure C.1 and Figure C.2 show the Factor Creation and Response Creation dialog boxes for the repair shop model.
