Create Control Chart Manually
Explanation
This activity is used to create a control chart manually for a specific control plan line (data point).
- p Chart - Gives information about the proportion of nonconforming units.
- np Chart - Gives information about the number of nonconforming units.
- c Chart - Gives information about the number of nonconformities.
- u Chart - Gives information about the number of nonconformities per unit.
- Xbar and R Chart - Gives information about the average and the range of the result set of
each analysis selected in the graph.
- Xbar and S Chart - Gives information about the average and the standard deviation of the
result set of each analysis selected in the graph.
- X and MR Chart - Gives information about individual results and moving ranges for each
analysis selected in the graph.
An analysis will not be included in creating a chart if any of the following conditions exist:
- The status of the data point is Incomplete.
- The analysis result is in the Cancelled status.
- The defined fixed sample size of the data point and the resulting sample size of the analysis results do not
match. (This does not apply for the p chart and u chart.)
To create a control chart for a specific data point click Create SPC Chart on the
Control Plan Lines tab, eventually update the information displayed in the
Create SPC Chart dialog and click OK.
Prerequisites
- To create a control chart for a specific control plan line, the corresponding control plan must exist, with
at least two created analyses in status Complete.
- SPC is enabled for the control plan line.
