This report displays the change over time of the proportion of units within a given sample size that have at least one defect.
It displays a chart and a table illustrating the control level of plant manufacturing.
To use this chart set a base date (the date from which the report starts) and then enters the number of days the chart will cover.
The line chart for the p Chart Report displays a graphical representation of the percentage of bad units.
There are four lines contained in the line chart. They are as follows:
● Top Red Dashed Line – Upper Control Limit (UCL)
● Bottom Red Dashed Line – Lower Control Limit (LCL)
● Solid Green Line – Middle of the two control limits
● Solid Blue Line – Pct. Bad
When the data points fall outside of the upper and lower control limits the manufacturing process is considered to be uncontrolled. Those points have a red circle around them.
The table for the p Chart Report displays the following information for each of the days in the range.
● Pct Bad - The percentage of units on the given day that have at least one defect.
● Defects - The number of defects that occurred on the day.
● Sample- The size of the sample on the given day.
