Next steps
You’ve succeeded in modeling, simulating, visualizing, and analyzing a simple mortgage
application process. To further explore Arena’s capabilities, try solving a few of these
extensions to the process.
1. Add a screening process before the application is reviewed.
Applications can be screened in as little as 15 minutes. Most often, it takes about 25
minutes for the screening, though sometimes it can require as much as 45 minutes.
Assign a Receptionist (rate of $6.75/hour) to perform the screening. What proportion
of the Receptionist’s time will be used in this task?
2. Return some applications to the mortgage applicants after the screening process.
On completion of the screening, 8% of the applications are returned. Also, because
many of the deficient applications are caught in the new screening, the percentage of
applications that are accepted in the formal review is raised from 88% to 94%, and the
Mortgage Review process time is reduced by 10%. By how much did the cost of
reviewing an application change? How about the total time to review applications?
