Process Capability Control Charts

The Process Capability Control Chart displays data based on actual inspection results. The chart consists of an upper and a lower plotting area. The upper plotting area is used to monitor the process mean and the lower plotting area is used to monitor the process deviation from the mean.

Use Filter to modify the settings as required. For all the entities (order origin, item, business partner and so on), you can set the filter to include all the data in the specified range or select a specific entity.

These are the three most commonly used chart types:

• Xbar and R control charts: This chart is used where the sample size is constant and relatively small. See To create Xbar and R control charts
• Xbar and S control charts: This chart is used where the sample size is variable, or relatively large, or both. See To create Xbar and S control charts
• Xm and R control charts: This chart is used when the characteristic of sample size is more dynamic and varied possibly due to inherent instability in the process that is executed. See To create Xm and R control charts
