In the context of quality control, the 80/20 rule can be used to identify the most critical issues by separating "the trivial many" from "the vital few": Approximately 20% of the defects or issues in a process, product, or system are responsible for approximately 80% of the overall quality problems. Once an organization identifies the "vital few" problem areas, then the organization can (i) allocate resources to address/solve these problems, (ii) prioritize resources and focus on the areas that would have the most significant impact on overall quality, (iii) identify root causes of the most critical issues ("the vital few") and eliminate those root causes for continuous improvement and more sustainable quality improvements. It's important to note that the 80/20 rule is not a strict mathematical law but rather a guideline." (A draft of the above quote was generated by ChatGPT on October 25, 2023 in response to an inqury on use of 80/20 rule in quality control and management. The information was verified and edited for bravity.) Use the information above to answer the questions. a) (5 points) A hotel chain has received several complaints from the guests who stayed at one of their properties. A quality manager at the hotel, with the help of the analytics team, classified the complaints received in the last 12 months. A summary of guests' comments and the frequency of complaints is available on this worksheet. Analyze the complaint data to identify the "vital few" issues at this hotel property: First, sort the comments from the most frequent to the least frequent and then compute the percentage of complaints received for each comment. What are the "vital few" comments, i.e., which comments constitute the top 80% of all the complaints? Which categories are associated with the "vital few" comments? b) (6 points) Make three recommendations to the hotel to improve the quality. Make sure your proposal addresses the "vital few" issues you identified in part a. NOTE-1: SHOW ALL YOUR WORK. USE 4 DECIMAL PLACES IN ALL CALCULATIONS. MAKE SURE YOU CLEARLY LABEL AND HIGHLIGHT YOUR ANSWERS TO EACH QUESTION. NOTE-2: Instead of using online tutoring services or websites to get the answers, you are encouraged to ask for assistance from your instructor. The instructor knows how the problem should be solved, which formula needs to be used, and what the contents of the course are. And, the instructor's office hours are FREE OF CHARGE! Plus, seeking outside assistance or sharing the questions electronically or in other form with other teams, platforms, websites, messaging boards, tutors etc. is in violation of the Academic Integrity Code of AU.
