Name DAD 220 Project Two Scenario The product manager of Quantigration has asked your data analytics team for a report summarizing your analysis of the return merchandise authorizations (RMAs) that have been received. These are the same data sets that you’ve already been working with. Your report should focus on summarizing the analysis and presenting your findings to the product manager. Directions RMA Report In your report, respond to the manager’s requests: to summarize the data you’ve been working with and to identify key information that will help the company streamline operations. Remember, not everyone who reviews this report will have a technical background. 1. Begin by writing SQL commands to capture usable data (which you’ve preloaded into Codio) for your analysis. 2. Specifically, the product manager wants you to analyze the following: o Analyze the number of returns by state and describe your findings in your report. 1. SELECT Customers.State AS STATE, COUNT(*) AS RETURN_FREQUENCY FROM Orders INNER JOIN RMA ON Orders.OrderID = RMA.OrderID INNER JOIN Customers ON Customers.CustomerID = Orders.CustomerID GROUP BY STATE ORDER BY RETURN_FREQUENCY DESC; Downloaded by Jairo Borges (jborges0214@gmail.com) lOMoARcPSD|30215168
2. 3. It appears that MA, AK, WV are the top three highest return frequency states. 4. Downloaded by Jairo Borges (jborges0214@gmail.com) lOMoARcPSD|30215168

5. BAS-48-1c has been returned 8422 times while the next highest is ENT- 48-40F has been returned 6213 times. Lastly the third highest is ENT-48- 10F with a return number of 4345. o Analyze the percentage of returns by product type and describe your findings in your report. 1. SELECT Customers.State AS STATE, (COUNT(*) * 100/ (SELECT COUNT(*) FROM Orders INNER JOIN RMA ON Orders.OrderID = RMA.OrderID)) AS RETURN_PERCENTAGE FROM Orders INNER JOIN RMA ON Orders.OrderID = RMA.OrderID INNER JOIN Customers ON Customers.CustomerID = Orders.CustomerID GROUP BY STATE Order BY RETURN_PERCENTAGE DESC; 2. 3. It appears that MA, AK, WV are also the highest return percentage states. 4. Downloaded by Jairo Borges (jborges0214@gmail.com) lOMoARcPSD|30215168
5. The highest percentage is 22% (BAS-48-1c), 16% (ENT-48-40F), 11% (ENT-48-10F). 3. In your report, clearly summarize your analysis of the data for stakeholders . Include screenshots of the results of each query. When summarizing results, you may want to consider the following questions: o How does the data provide the product manager with usable information? 1. This information aids in representing the region where most returns occur so that additional research can be done to see why this particular location has the greatest number of returns. The information generated by the usable data that was gathered can be useful information for the product manager to understand how sales are going and what is being returned. Based on the returns, it is possible to discover why they are being returned. The corporation will be able to adapt and make changes to these products if the product turns out to be defective. o What are the potential flaws in the data that has been presented? 1. This information does not truly narrow down the actual reasons why they were returned or whether the products could have originated from the same client who ordered them, and the data could have been recorded erroneously, resulting in inaccurate information when compiling data reports. o Are there any limitations on your conclusions, or any other ways of looking at it that you haven’t considered? Clearly communicate your findings to stakeholders. 1. Some limitations could be that there needs to be more in-depth investigation on to what is wrong with the item with the highest return percentage per state. o Clearly communicate your findings to stakeholders. 1. According to the information collected, there appears to be a high number of returns in the state of Massachusetts. The product with the greatest return rate is the Basic Switch 10/100/1000 BaseT 48 port. If there could be a more information found out on why things are being returned and what changes could be made to correct the problem this would bring the percentage down.
