Control Charts

Control charts are graphical representations of data that is associated with a process, plotted over time.

Use these charts to:

Monitor a process to determine stability.
Visualize trends and variability.
Note and track process adjustments.
Investigate causes of unacceptable or marginal quality.

PeopleSoft provides you with seven industry-standard control charts. These charts are time-series charts for monitoring and controlling processes or equipment. Each control chart has a unique chart ID that represents a different display format.

Using the Control Chart component, you can define custom charts to reflect special control requirements or labeling conventions. The charts are based on industry-standard control charts and are applicable to a specific data type.

Note:

Chart IDs 1 through 7 are supplied as industry-standard system defaults.

Chart ID	Description	Data Type
1	X and Moving Range.	Variables
2	Xbar and Range.	Variables
3	Xbar and Sigma.	Variables
4	c Chart.	Defects
5	u Chart.	Defects
6	p Chart.	Defectives
7	np Chart.	Defectives

These tables illustrate the structure of each control chart.

Note:

Some control charts are comprised of two individual subcharts for plotting means and variances together. These subcharts are labeled as chart 1 or chart 2 in the tables.
