Answer C only. Tim Woods, a recent GMU MBA grad and serial entrepreneur, has opened Pets-R-awesOMe, an online pet store. He and his team are experimenting with call center staffing. A. The current call center format has two lines: one for customers who want to place an order and one for customers who want to report a problem. Each line is served by one specialized customer service representative. The call center is staffed so that at any given time, there is one representative taking customer orders and one representative addressing customer problems. On average, there is a new customer who wants to place an order every two minutes, exponentially distributed. Similarly, there is a new customer needing to address a problem every two minutes, exponentially distributed. The call center staffers are fast and can on average complete one call of either type in 75 seconds, with a standard deviation of 30 seconds. Each call center staff member is paid $15 per hour. The estimated cost of a…

Employee Wanda Trews was working in the manufacturing facility at Coves Industrial. The employees of Coves Industrial manufacture diesel engines for the airline industry. Wanda works on Line 3 in the facility and from time-to-time works on Line 7 as a relief worker to cover employee breaks. Wanda was asked to leave Line 3 and provide break coverage on Line 7 for 2 hours on September 19, 2021. Earlier that day, there had been a mechanical difficulty with the stamping machine on Line 7. The maintenance team was able to get the machine working again but they call the manufacturer of the stamping machine as the machine doesn’t sound right and it clearly needs further maintenance. When Wanda arrived at Line 7 to provide break coverage, she checks in with Line 7 supervisor Raoul Steves. Raoul advises that Wanda needs to manufacture 200 components during her 2 hours on Line 7 and to let him know if she needs any help. Raoul does not mention the earlier mechanical issue with…
