Design of experiments is a statistical methodology often used in six-sigma projects.It aims to accomplish which of the following?
A)Keep careful track of the occurrences of each possible defect
B)Determine the cause and effect relationships between process variables and output
C)Report defects to management on a Pareto chart
D)Carefully change each individual process variable until the cause of a defect is found
E)Eliminate defects by finding out whom or what is causing them

Question

Quizplus · Accepted Answer

Design of experiments is used to determine the cause and effect relationships between process variables and output. It involves changing multiple variables at once to identify which variable(s) have the greatest impact on the output. This helps in identifying the root cause of defects and in improving the process. It is not about tracking defects or reporting them on a Pareto chart, nor is it about changing each individual process variable until the cause of a defect is found. Eliminating defects is a goal of the methodology, but it is not achieved by finding out who or what is causing them.
