Use the following information to answer Questions 2-19. Suppose you are leading a team to help H&R Block (a tax preparation company) improve its tax preparation service process. After several field trips to the company, you decided that tax preparation process consists of two activities: (i) preparing necessary documents (DocPrep, hereafter) performed by a team led by Ted, followed by (ii) completing tax return forms (FormPrep, hereafter) performed by a team led by Mary. You built the following model in ExtendSim to simulate this process (also available from Flow chart base model.pdf in case the picture does not show up). Answer Questions 12-14 also considering the following information To see how long a request waits in the process on average, you updated the simulation model into the following (also available from Model 3.pdf). How long does a request wait in the process on average (see below the Statistics tab of the dialog of Information block; all numbers in the unit of min; also available from Information.pdf)?
