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 to how well an organization controls them.
This template will significantly support 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
