Part 2.5 Policy Memorandum Final



Assignment Preparation:

You can complete this assignment after reading Chapters 3 and 4 in your textbook and Writing Assignment 2.1. The problem involves selecting a major vendor through comparative analysis.



Assignment 2.5:

Review and revise your document using the input from your classmate to assist your own revision process. Be sure to edit the document for grammar and spelling prior to turning it in. For convenient reference, the assignment is included below.


Problem description:

You oversee a manufacturing facility that produces an automotive part (steel shaft for the gearbox). The acceptable dimension of the shaft is 2.5±0.05 inches in diameter with the most desirable product having a diameter of exactly 2.5 inches. Two vendors are trying to sell your company, Automotive Parts Corporation, their machines for the shaft-machining task. You have been asked to assess the machines from each vendor, and to make a recommendation for a machine vendor supported by a justification for your decision.

You asked both vendors to supply data on the machining accuracy of their machines for the given task. Both vendors machined 100 shafts, collected data, plotted histograms, fitted the histograms with normal distributions and supplied you with their findings.

Let X= diameter in inches of the gearbox shaft

Ace Machines: X has a normal distribution with mean 2.48 and variance 0.001

Best Machinery: X has a normal distribution with mean 2.51 and variance 0.002

When you are completing your memorandum be sure to address the following:

  • Recommend a vendor using the given information, develop and discuss your approach (give all details including quantitative justification). Your response to this question must be directed to the audience described below.
  • Examine the scenario as described and discuss what additional information would be helpful to make this recommendation a stronger selection, and why that information would be useful. Be careful not to negate your recommendation as you explain this.
  • Include your calculations as a titled addendum on its own page at the end of your document

MEMORANDUM
To: Lin Gerard, COO, Automotive Parts Corporation
CC: Aileen Kitts, CFO, Automotive Parts Corporation
Rosalyn Barnes, Chairperson Board of Directors, Automotive Parts Corporation
Keith Carter, CEO, Automotive Parts Corporation
From: Saif Alkaabi, Quality Control, Automotive Parts Corporation
Date: March 24th, 2019
Subject: Recommendation for Shaft-Machining Equipment
Summary
It is recommended that the Chief Operating Officer review this memo, the attached statistical
calculations, and analysis, and adopt the recommendation that the company should procure shaftmaking equipment from Ace Machines.
Analysis
Two companies, Ace Machines, and Best Machinery are trying to sell their equipment for the
shaft-making task to Automotive Parts Corporation. As the one in charge of Quality Control at
Automotive Parts Corporation, I asked the two vendors to supply data on the accuracy of their
machines. They both complied by machining 100 shafts after which they determined the normal
distribution from plotted histograms and submitted the collected data for consideration.
The most desirable product should have a diameter of 2.5 inches. However, an acceptable error
of ±0.05 is allowed. The mean and variance of the submitted data respectively is as indicated
below;


Ace Machines: Mean = 2.48 inches, Variance = 0.001
Best Machinery: Mean = 2.51 inches, Variance = 0.002
The accuracy of the steel shaft diameter of the gearbox is critical for its proper working.
Therefore, choosing a vendor that has a higher chance of providing the most desirable diameter
is vital. Given the company’s allowable range is 2.45 inches to 2.55 inches, it is clear that the
average diameter from both vendors is acceptable. As such, I had to look at the standard
deviation of the data supplied. The standard deviation of the diameter of the shafts produced by
Ace is 0.032 and by Best is 0.045. That, then, gives a tolerance limit of 0.06 and 0.09 for Ace
Machines and Best machinery respectively.

From the analysis, indicated in the table, one can note that Ace has a smaller variability
compared to Best Machinery. As such, the better precision of Ace Machines makes it a more
preferred choice over Best. Hence the vendor of choice with just the given information and no
additional information would be Ace Machinery.
Conclusion
It is my recommendation, following the analysis of supplied data from both vendors that the
Chief Operating Officer adopts the recommendation of procuring shaft-making equipment from
Ace Machines.

My classmate used an appropriate header for the memorandum. All the details about the
header are addressed correctly. The subject is not clear because it does not specify what the
vendor will be supplying. It can be any product or item; therefore, it must be specific that it is the
steal shaft for the gearbox part that is going to be supplied. What needs to be stated n the subject
is “Selecting A Major Vendor to supply a Steal shaft for the gearbox part.”After going through
the analysis part, I did not understand how range would be applicable considering that Ace
machine range is small as compared to that of Best Machine. It is not clear because there is no
explanation of how the size of a range is a factor when choosing the product. Maybe my
classmate should explain briefly, on how a small range and large range will affect the choice of
the Steal shaft that the two vendors provide. One of the aspects that made the memorandum
helpful is when my classmate explains that the desirable diameter for the product should be
exactly 2.5 inches and an acceptable dimension is 2.5±0.05 inches. Mentioning the use of the
chart to determine the range was also helpful. This made it easy to understand what was needed
to be looked at when choosing a product from one of the vendors. My classmate utilized
professional writing style needed in writing a memorandum. A good example is typing the
“MEMORANDUM” on top of the page followed by the header and subject indented on the left.

Wesley Beyer
My classmate used the appropriate header for the memorandum and the information is
correct. The subject is clear and concise given that the objective of analyzing a new shaft is
mentioned. The information provides by my classmate is correct given that dimensions are stated
with support from the visuals. Having gone through the memo from my friend, I found all parts
to be very clear and don’t need any changes to be made. The visuals especially the graph was
very helpful in understanding the probabilities of choosing the right size shaft. My classmate also
gave additional considerations and statistical calculations that perfectly summarized all the
necessary factors needed when choosing the gearbox shafts. My classmate utilized all the
necessary writing style required in a memorandum. A good example is typing the
“Memorandum” on top of the page followed by the header and subject indented on the left.
Exceeded minimum writing requirements
Robinson Simon
My classmate used the appropriate header for the memorandum. The information on the
header is correct. I think the subject does not concisely state the objective of the memorandum. I
think the subject should be “Find a suitable vendor for Automotive Gearbox Steel Shaft”. All the
justifications provide by my classmate are clear. The statistical calculations were particularly
helpful in the probability of the Automotive Gearbox Steel Shafts from the two vendors. My
classmate was also very clear in highlighting the dimensions of the shafts. The professional
writing style was well utilized especially formatting of the paper and organization in the form of
a memo. The heard and subject are clearly indented on the top left corner of the paper. The

visuals made the explanations very clear especially the use of graphs to highlight the probability
