The special librarians take an average of 4 minutes to fill a first-edition book retrieval, and 6 minutes to fill an original manuscript or author's journal retrieval. Worksheet Exhibit 7.14 may be helpful in answering questions about the the front-office activities from the back-office activities. Here, library patrons must follow a very small number of predefined pathways through the service delivery system.

Assume the throughput rate defined by Exhibit 7.13 is 40 library patrons per hour. All library patrons must re- main in the visitor's area until they register with one of the head librarians. On average, there are 10 people waiting in the visitor's area. The head librarians verify that the patron has accounts in good standing with the library; this activity averages 3 minutes. After registering, the patron moves to a reference waiting area. On average, 12 people are waiting to be serviced in this second waiting area. A special librarian then takes the request from the patron and guides him or her to one of three smaller wait- ing areas in the library: first editions, manuscripts, and authors' journals. This first special librarian activity aver- ages 4 minutes and is the first of two activities carried out by the special librarian. One special librarian handles one customer at a time. On average, 50 percent of the patrons ask to see first editions, 40 percent ask for original manu- scripts, and 10 percent ask for authors' journals. When pa- trons arrive at one of the three smaller waiting areas, they wait for the special librarian to perform the second activ- ity, which is finding and retrieving the item. The library staff estimates, on average, that five people are waiting to be served for first-edition books, three people waiting to Case Questions for Discussion 1. How many minutes, on average, does it take for a first-edition patron to get the requested book from time of entry into the library? (State all assumptions and show the calculations.) 2. How many minutes, on average, does it take for the average library patron to get the requested book from time of entry into the library? (State all assumptions and show the calculations.) 3. How many patrons, on average, are there in the total library service delivery system? (State all assumptions and show the calculations.) 4. If the following numbers of employees work at each activity, what is labor utilization for each job activity? Head librarian: two employees, 3 minutes per activity; special librarian check-in: three employees, 4 minutes per activity; first-edition retrieval: two employees, 4 minutes per activity; original manuscript retrieval: two employees, 6 minutes per activity; and authors' journal retrieval: one employee, 6 minutes per activity. 5. What labor resource is the bottleneck? 6. What do you recommend to break the bottleneck(s)? Explain and justify your reasoning.
