1. What's the maximum number of application per hour that can be handled by the present configuration of process?
We can use the formula 1 hour * 60 minutes * 60 seconds/ Average Time to Perform (second) to calculate the each step can handle how many check every hour, in which how many applications per hour.
Step 1: Review renewal application for correctness: 1 h*60 min*60 sec/15sec=240
Step 2: Process and record payment: 1h*60min*60sec/30sec=120
Step 3:Check file for violations and restrictions: 1h*60min*60 sec/ 60sec= 60
Step 4: Conduct eye test: 1h*60min*60sec/ 40sec=90
Step 5: Photograph applicant: 1h*60min*60sec/20sec=180
Step 6: Issue temporary license: 1h*60min*60sec/30sec=120
Because the Step 3: Check file for violations and restrictions application per hour is only 60, so the whole process for application per hour is 60.
2. How many applications can be processed per hour if a second clerk is added to check for violations?
From the exhibit TN6.19 we know that each check file for violations and restrictions need 60seconds.So if add a clerk, 60seconds can do two of the check file for violations and restrictions. And we know that a violation is the slowest. So add a more clerk about it. They can do 120 applicants per hour.
3: Assuming the addition of one more clerk, what is the maximum number of applications the process can handle? Step | Average time | Number of application | Number of application if add second clerk | | | | 1 | 2 | 3 | 4 | 5 | 6 | 1 | 15 | 240 | 480 | 240 | 240 | 240 | 240 | 240 | 2 | 30 | 120 | 120 | 240 | 120 | 120 | 120 | 120 | 3 | 60 | 60 | 60 | 60 | 120 | 60 | 60 | 60 | 4 | 40 | 90 | 90 | 90 | 90 | 180 | 90 | 90 | 5 | 20 | 180 | 180 | 180 | 180 | 180 | 360 | 180 | 6 | 30 | 120 | 120 | 120 | 120 | 120 | 120 | 240 | Max application | 60 | 60 | 60 | 90 | 60 | 60 | 60 |
In this charter, we can see the effect of adding an
