Question
The Cp of a process is calculated at 2.00. What does this tell us about the process?Multiple ChoiceThe process is not capable.The process width is half of the specification width.The specification must be modified by a factor of 2.00.The specification is too wide and should be changed.
Solution
The Cp value of a process is a measure of process capability. It tells us how well the process can meet the specification limits, assuming that the process is centered in the specification range.
A Cp of 2.00 means that the process is capable. Specifically, it indicates that the process width is half of the specification width. This is because the Cp is calculated as the ratio of the specification range to the process range, and a Cp of 2.00 means the process range fits within the specification range twice.
Therefore, the correct answer to the multiple choice question is: "The process width is half of the specification width."
