Question Problem 11-03 (Algorithmic) Willow Brook National Bank operates a drive-up teller window that allows customers to complete bank transactions without getting out of their cars. On weekday mornings, arrivals to the drive-up teller window occur at random, with an arrival rate of 30 customers per hour or 0.5 customers per minute. In the same bank waiting line system, assume that the service times for the drive-up teller follow an exponential probability distribution with a service rate of 36 customers per hour, or 0.6 customers per minute. Determine the following operating characteristics for the system: a. The probability that no customers are in the system. If required, round your answer to four decimal places. Po = b. The average number of customers waiting. If required, round your answer to four decimal places. Lq = C. The average number of customers in the system. If required, round your answer to nearest whole number. L = d. The average time a customer spends waiting. If required, round your answer to four decimal places. Wq = min e. The average time a customer spends in the system. If required, round your answer to nearest whole number. W = min f. The probability that arriving customers will have to wait for service. If required, round your answer to four decimal places. Pw =

Accounting, Inc. is a consulting and accounting firm headquartered in Amsterdam, the Netherlands. Recently, Accounting, Inc. implemented a performance management system. The first step in the implementation of the new system was the development of a set of core competencies that would be used to evaluate most employees regardless of function or level. In addition, each employee was evaluated using more job-specific performance dimensions. As the first step in the communication plan, the employees received individual e-mail messages asking them to define what the core competencies meant to them and to give descriptions and examples of how each of the core competencies played out in their specific positions. Next, the company held meetings, handed out frequently asked questions (FAQs) sheets, and placed posters around the company detailing how the core competencies were related to the organization’s strategic priorities and how performance scores would be related to monetary rewards. In these communications, Accounting, Inc. detailed how the performance system worked, how the raters were chosen, how performance feedback was used, and other details about the system. The information also outlined the benefits employees could expect from the new system as well as employees’ responsibilities regarding the system. When the system was implemented many employees were not happy with the scores and the type of performance feedback information they received from their supervisors. Questions: Please evaluate Accounting, Inc.’s communication plan. Specifically, does it answer all of the questions that a good communication plan should answer? Which questions are left unanswered? How would you provide answers to the unanswered questions (if any)? If you were to design an appeals process to handle these complaints well, what would the appeals process be like?
