1. How many applications can be processed per hour if a second clerk is added to check for violations?
2. If the second clerk could be added anywhere you choose (and not necessarily to check for violations, as in Question 1), what is the maximum number of applications the process can handle? What is the new configuration?

Automobile Licence Renewals Manuel DeSousa, the manager of a metropolitan branch office of the Ministry of Transportation, attempted to analyze the driver's licence-renewal operations. He had to perform several steps. After examining the licence-renewal process, he identified those steps and associated times required to perform each step, as shown in the following table: DeSousa found that each step was assigned to a different person. Each application was a separate process in the sequence shown. He determined that his office should be prepared to accommodate a maximum demand of processing 120 renewal applicants per hour. He observed that work was unevenly divided among clerks and that the clerk responsible for checking violations tended to shortcut her task to keep up with the others. Long lines built up during the maximum-demand periods. DeSousa also found that Steps 1 to 4 were handled by general clerks who were each paid $12 per hour. Step 5 was performed by a photographer paid $16 per hour. (Branch offices were charged $10 per hour for each camera to perform photography.) Step 6, issuing temporary licences, was required by provincial policy to be handled by uniformed motor vehicle officers. Officers were paid $18 per hour but could be assigned to any job except photography. A review of the jobs indicated that Step 1, reviewing applications for correctness, had to be performed before any other step could be taken. Similarly, Step 6, issuing temporary licences, could not be performed until all the other steps were completed. Manuel DeSousa was under severe pressure to increase productivity and reduce costs, but he was also told by the regional director that he must accommodate the demand for renewals. Otherwise, "heads would roll
