The process is centered on the target value. Is the Cpk greater than 1.0?
Yes No
Is the Cpk equal to the Cp?
The process has “high” capability. Is the Cpk equal to the Cp?
The process is capable of producing output within specifications.
Is the Cp greater than 2.0?
The process is not capable of producing within specification limits. Look for ways to improve the process by reducing common cause variation. You may also need to evaluate the specification limits to determine if they are current.
Perform capability analysis to learn if the process is capable of producing output that meets specification requirements. For more information, select:
