CASE STUDY: MORTGAGE APPROVAL TIME STUDY
Case Study: Mortgage Approval Time Study
Read the following case study:
A major financial services company wishes to better understand its
mortgage approval process. In particular, the company is interested in learning
about the effects of good versus fair credit history, the size of the mortgage
(less than $500,000 versus greater than $500,000), and the region of the United
States (western versus eastern) on the time it takes to get a mortgage
approved. The database of mortgages approved in the last year is accessed, and
a random sample of five approved mortgages is chosen for each of the eight
combinations of the three variables. The data are shown in the table.

First, conduct an analysis using the following steps:
1. Use the data shown
in the table to conduct a design of experiment (DOE) in Microsoft Excel to
determine the nature and magnitude of the effects of the three variables on
mortgage approval times. Identify the key drivers of this process.
2. Determine the
graphical display tool (Interaction Effects Chart, Scatter Chart, et cetera)
that you would use to present the results of the DOE you conducted in Question
1. Provide a rationale for your response.
3. Assess the data
sampling method:
o Determine if the
sample size is sufficient.
o Identify
circumstances under which would it have been appropriate to select a
larger sample. Determine whether a sample of five mortgages is adequate to
access the relative magnitudes of the effects of the variables.
o Recommend
a sample size for future study and discuss what analysis can be made
with a larger sample size. (Hint: Look back at Chapters 2, 3, 5, and 6 for
discussion of sampling.)
Provide other variable responses that might be of interest to measure
and study. (Hint: If you were getting a mortgage or a loan, what are the two
most important measures of the process you would have to go through?)
Propose one overall recommendation to the financial services company
based on the DOE that could help reduce mortgage approval times.
Use Basic Search:
Strayer University Online Library to identify at least two
quality references to support your discussion. Note: Wikipedia and other
websites do not qualify as academic resources.
Second, create a PowerPoint presentation to communicate the data
analysis you completed. Your submission must meet these requirements:
·
A PowerPoint presentation with at least 10 content slides that
include the answers to questions 1 through 5.
·
A reference slide and cover slide with the title of the assignment,
your name, the professor's name, the course title, and the date.
o Note: The cover and
reference slides are not included in the required number of slides.
Formatting of the slides should be consistent and easy to read.
This course requires the use of Strayer Writing Standards. For
assistance and information, please refer to the Strayer Writing Standards link
in the left-hand menu of your course. Check with your professor for any
additional instructions.
The specific course learning outcome associated with this assignment is:
·
Develop recommendations to improve business processes using statistical
tools and analysis.
