- The sales manager of STC Telecommunication Company, conducts interviews of the sales representatives. During the interview, these questions were asked from the sales representatives which are related to the performance of their job: the percentage of the time spent in making presentations to new potential customers, telephone conversation with current customers, time spent working on the computer, and engaging in on- the job activities. What potential sources of error might be associated with the manager’s line of questioning specifically on the different tasks performed by the sales representatives?arrow_forwardTaylor Swiftt works at a call center as an analyst.

While he won’t get fired for it, being late this once means that he will not receive the perfect attendance incentive which he needs to make ends meet, given his daughter’s recent series of hospitalizations. It’s not that Jason didn’t make an effort to be there on time. He actually arrived in the office five minutes early but was unable to clock in immediately because his direct superior, Raffy, asked him for an informal project progress report as soon as he walked in the door. As a Junior System Administrator, Jason has access and the capability to edit the company’s attendance records. He figures that since he was unable to punch in only because of his boss, it wouldn’t hurt to edit the timestamp on his attendance for today.

An automobile dealer is planning a new custom service center to repair the microcomputer-based engine controls in new-model cars. With the new diag- nostic equipment they are installing, each job should take about 75 minutes to complete. The dealer plans to operate the center 8 hours per day. Preliminary estimates suggest that about 5 customers will bring their cars for repair each day. To analyze this situation, make the following assumptions: The customer arrivals form a Poisson process. Each job requires on average 75 minutes. We can ignore the time that the service center is closed. (That is, no arrivals occur during such gaps, and we don't count them in the total response time.) (a) Measure time in hours. In the terms of queueing theory, what are A, μ, and p? (b) Compute an estimate of the average total response time (which we call Ts). 2 (c) Estimate the average number of cars in the center (including those waiting as well as in service).
