Case 10.1 Motive Power Company – part 1
Executive Summary
In case 10 .1 Motive Power Company Part 1, manufacturing manager Cregg Hart is approached by another supplier for rivets. Motive Power is very keen on their quality and are interested in evaluating the new rivets by comparing them to their existing supplier’s rivets. Specifically this is done by comparing the diameters of the two groups of rivets.
After collecting data a 95% confidence interval was computed and a statistical test was performed to determine if the average diameters of the two groups of rivets are the same.
Conclusions from both statistical techniques led us to believe that both rivet suppliers on average provide rivets with about the same diameters. Therefore supplier with less expensive rivets should be given consideration for future needs.
Analysis:
Data for case 10.1 was obtained from the CANVAS class web page in an Excel file format. …show more content…
These cases are open ended situations – often they don’t ask you to do specifically anything. You are to use the material learned in the chapter and perform analysis and suggest recommendations.
Up to four students can work on the case analysis together. You are to submit only one copy of the case write-up with the names of the collaborators on the cover page. Your case analysis write-up should be single space and needs to include the following:
1. Cover Page: Your name(s), class name & period, the name of the case
2. First Page: This should include Executive Summary. An executive summary is a brief description of the situation, it describes the problem or challenge at hand, what analysis
you did and what results you found. It is usually written last.
3. Analysis Page(s): Here you do the analysis using Excel usually. Paste any Excel output and describe in English “what’s goin on”.
4. Conclusion recommendations Page: It should include what you are
