A process capability index of two centered on the mean just meets Six Sigma standards. (Points : 1)
True
False
false
True
To determine if the statement is true or false, we need to understand what a process capability index (Cpk) is and how it relates to Six Sigma standards.
Cpk is a statistical measure that assesses the capability of a process to meet specifications. It measures how well a process can perform within the limits of the customer's requirements. Cpk is calculated using data from the process and compares the spread of the process output to the desired specifications.
Six Sigma is a methodology used to improve the quality and performance of a process. It aims to reduce defects and variability, ultimately resulting in near-perfect performance. One of the key principles of Six Sigma is that the process should have a high level of capability, usually defined as having a Cpk of at least 1.33.
If a process has a Cpk of two, it means that the process is capable of performing within the specification limits with a significant margin. In other words, the process has a low level of variability and is meeting customer requirements with ample room for improvement. This level of capability exceeds the minimum requirement of 1.33 for Six Sigma standards.
Therefore, the statement is true. A process capability index of two centered on the mean just meets Six Sigma standards.
