Quality Analyst you are seeing the defects trend by type of defects and are plotting a histogram to do a Pareto analysis. Invent your own data to come up with a Pareto diagram, clearly identifying the top 20% category of defects and once done, deep-dive into the top category to do an Root Cause Analysis and come up with corrective action and preventive action plan. Please state your assumptions clearly at the beginning of your answer. a. Plot a neat histogram on plain paper, and identify the top 20% of the category of defects which contribute to 80% of the total volume of defects. [2 marks] b. Once you identify these top 20% defects, perform a Root Cause Analysis for the Top Contributing Factor using either 5-Why or the Fish-bone diagram method. [4 marks] c. Then, come up with a suitable corrective action plan and a preventive action plan to address the root cause, which should include who will do what. [4 marks]
