Question

Quizplus · Accepted Answer

A) The shape of the process data distribution can affect process capability as it determines the spread of the data and how far it is from the target. A normal distribution is preferred as it represents a stable process.
C) The process standard deviation is a measure of process variation and is directly related to process capability. The lower the process standard deviation, the higher the process capability.
D) The presence of special causes indicates that the process is not stable, and therefore the process capability cannot be determined accurately. Common causes of variation can be controlled, but special causes require corrective action.
E) Seasonal variation in the process can affect the mean and standard deviation, and therefore impact the process capability.
