A Stratification Tree Diagram is a great tool to collect additional X factors to help find root causes to a problem. The following are the steps for creating a tree diagram. - Determine the Output measure (Y) or primary metric - Brainstorm the key questions about the primary metric or that might impact the output Y - Extract the Stratification Factors (X) from the questions generated - Create metrics that can be collected to represent each stratification factor.

An Industrial Engineer is investigating the registration time at a COVID test site. They need to determine how many samples are required to observe a difference in the average registration time of 10 minutes which is the largest margin of error the test site is willing to accept. Based on a previous study, the team estimated the average registration time to be 45 minutes with a standard deviation equal to 20 minutes. What is the minimum sample size required to be able to estimate the average registration time while maintaining the stated margin of error? The COVID test site would like to maintain a level of confidence equal to 95%.
