Visit a retailer website (like Home Depot, Lowes, Amazon, etc.) and choose two related and comparable products from two different competitors. For example you can choose 42 in riding tractors from Cub Cadet and John Deere. Sort the reviews for the products by their lowest ratings. Pick at least 30 bad reviews for each product and classify the complaints you found in them into four or five categories. Then use three different quality tools to analyze your data and provide a discussion on your findings.
