The manager of the Personnel Department at City Enterprises has been reading about time-driven ABC and wants to apply it to her department. She has identified four basic activities her employees spend most of the their time on: Interviewing, Hiring, Assessment and Separation Processing. The department employs 7 staff who perform these activities. The manager provides the following estimates for the amount of time it takes 10 complete each of these activities . Interviewing: 85 minutes Hiring: 80 minutes. Assessment 115 minutas + Separation Processing: 110 minutes. Employees in Personnel work 33 haur weeks with four weeks for vacation. Of the 33 hours, five are reserved for administrative tasks, training, and so on. The costs of the Personnel Department, including any alacaled costs from other staff furclions, are $1.241.858. During the year, Personnel conducted 1.240 interviews, made 395 hires, inade 3.BOD assessments, and had 330 separations. The manager of the Personnel Department decides that her estimate of the activities might be too simple in two ways. First, the time to interview depends on the level of the position for which a candidate is sought. She estimates that for a candidate at the manacer level, the additional interviewing time is 160 minutes. (Personnel Department employees only conduct the initial interview, but they bocompany the candidate for interviews by the hiring executive or CEO.) For candidate at the executive level, the additional time for interviewing is 460 minutes in addition to the time required for a manager) The second issue she identifice is that the time for separation processing depends on whether the separation is voluntary. She estimates that an involuntary separation requires an additional 260 minutes of personnel time. Required: a. What is the total time required for the interviewing activity? minusas b.
