Tech U will be issuing a new smart ID card with magnetic strip to all of the students. The steps in the process and times are as follows. Step 1: Verify information on application (60 sec) Step 2: Take payment (45 sec) Step 3: Take photo (30 sec) Step 4: Wait for photo to print (15 sec) (This is not a workstation and no work is being performed) Step 5: Attach photo and magnetize (40 sec) Tech U is planning to have two workers at Step 1 with each worker serving a separate student (analogous to the two ovens in Kristens Cookies case). The other steps will have only one worker each. Step 4 is not assigned a worker since no work is being performed. Here is the process flow chart.

1. Verify -> 2. Payment -> 3. Take Photo -> 4. Wait for Photo -> 5. Attach photo & magnetize

a. What is the flow time in seconds for a student who has no other student ahead of him/her?

b. Find the capacity (in # of students per hour) at each step except for Step 4. Again, remember Step 1 has 2 workers.

c. Which step is the bottleneck?

d. What is the maximum number of students that can be served in an hour, i.e., capacity of the system?

e. If the waiting time at Step 4 can be reduced from 15 seconds to 5 seconds, what is are the flow time and the capacity of the system?

f. Assume the waiting time at Step 4 is still 15 seconds. If Step 1 has only one worker, what is the capacity of the system?
