In process improvement efforts, the process capability index or process capability ratio is a statistical measure of process capability: the ability of a process to produce output within specification limits. The concept of process capability only holds meaning for processes that are in a state of statistical control.
Process capability indices measure how much “natural variation” a process experiences relative to its specification limits and allows different processes to be compared with respect to how well an organization controls them.
This template will significantly supports you in calculating Cp/Cpk for any metrics or process parameters. You just input the measured values, the tolerances and the formulas will automatically calculate all the Cp/Cpk values.
- 2 different templates :
- calculation for a bilateral tolerance
- calculation for a unilateral tolerance
- Based on the measured values, the template automatically generates:
- Cp/Cpk values
- The mean
- UCL/LCL values
- Sample size
- 2 visual graphs
