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). With in-depth data analysis, your team determined that requests’ inter-arrival time follows exponential distribution with an average of 0.5 hr. To specify this distribution in ExtendSim, you opened the following dialog by double clicking on RequestIn block (also available from Picture1.pdf). What number should you put as the value of “mean” (see the circled part)?
