A Six Sigma project team was chartered to increase the final yield of a solar cell manufacturing process. The team is focusing on a critical process that accounts for more than 60% of the defective units. The process engineer has identified six variables that could potentially affect the output of this process. Which tool should the team use next in order to understand the cause & effect relationship between the variables and the process output? [tool]

The waste related to diagnostic tests is an opportunity for hospitals to decrease costs. The manager of a trauma unit at one hospital just launched a Six Sigma project aimed at reducing redundant diagnostic tests, with an expected cost reduction of 10%. Which tool should the team use to gain agreement on project boundaries and scope? [which]

The waste related to diagnostic tests is an opportunity for hospitals to decrease costs. The manager of a trauma unit at one hospital just launched a Six Sigma project aimed at reducing redundant diagnostic tests, with an expected cost reduction of 10%. Which tool should the team use to visualize the process steps connected to the Customer? [which]

A project team is tasked with improving the performance of the local hockey team. Based on published research the team decided to test two different methods to train healthy skeletal muscles. Seventeen (17) players were involved in the study, with eight in Group A and nine in Group B. The sample standard deviation of performance time was 0.09 seconds for Group A and 0.75 seconds for Group B. Assume that performance time follows a normal distribution. Which statistical test should be used to determine whether the groups have the same standard deviation of performance time? [test]

In comparison with a factorial experiment design, a one-factor-at-a-time (OFAT) approach will
