Types of Plots

This section deals with the plot types that are available in the Plot Viewer.

RPN (Pareto) shows the Risk Priority Numbers (RPNs) of the causes ranked from highest to lowest. You can view the initial RPNs only, the revised RPNs only, or both values in combination. If you view both values, you can select to sort by either initial or revised values.
RPN % Reduction Pareto shows the reduction in the RPNs of the causes, from the initial values to the revised values, ranked from the greatest percentage reduction to the lowest percentage reduction.
Occurrence/Severity Matrix displays the severity ratings on the horizontal axis and occurrence ratings on the vertical axis and then plots each cause at the intersection of its severity and occurrence ratings. You can specify whether you want to view the initial or the revised ratings, and you can use the Priority Area Coordinates area of the control panel to specify the end points for the high and low priority lines.

Note: Pointing to a point on the generated occurrence/severity matrix will display information about the cause, including its severity and occurrence ratings. Note that if your analysis contains a very large number of cause descriptions, pointing to a symbol in the matrix may not display all of the causes represented by that point. However, all causes are still displayed in the Plot Summary.

SxO Pareto shows the severity x occurrence values of the causes ranked from highest to lowest. You can view the initial severity x occurrence values only, the revised severity x occurrence values only, or both values in combination. If you view both values, you can select to sort by either initial or revised values.
Effect Severity Pareto shows the severity values of the effects ranked from highest to lowest. You can view the initial severity values only, the revised severity values only, or both values in combination. If you view both values, you can select to sort by either initial or revised values.
Cause Occurrence Pareto shows the occurrence values of the causes ranked from highest to lowest. You can view the initial occurrence values only, the revised occurrence values only, or both values in combination. If you view both values, you can select to sort by either initial or revised values.
Cause Detection Pareto shows the detection values of the causes ranked from highest to lowest. You can view the initial detection values only, the revised detection values only, or both values in combination. If you view both values, you can select to sort by either initial or revised values.
Effect Severity Pie shows the percentage of the effects in the selected analysis that are represented by each severity value displayed in the plot legend. You can view the initial severity values or the revised severity values.
Cause Occurrence Pie shows the percentage of the causes in the selected analysis that are represented by each occurrence value displayed in the plot legend. You can view the initial occurrence values or the revised occurrence values.
Cause Detection Pie shows the percentage of the causes in the selected analysis that are represented by each detection value displayed in the plot legend. You can view the initial detection values or the revised detection values.
Classification Pie shows the percentage of the causes in the selected analysis that are represented by each classification displayed in the plot legend.
Action Costs Pareto shows the cost values of the actions ranked from highest to lowest. You can view the actual values only, the estimated values only, or both values in combination. If you view both values, you can select to sort by either initial or revised values.
Action Status Pie shows the percentage of the actions in the selected analysis that are represented by each action status displayed in the plot legend.
Action Category Pie shows the percentage of the actions in the selected analysis that are represented by each category displayed in the plot legend.
Action Priority Pie shows the percentage of the actions in the selected analysis that are represented by each priority value displayed in the plot legend.

Note: For the "Action" plots, to exclude actions with a specific description, such as "None," you can select the Exclude Records with Description check box, then enter the specific values in the field.

Control Type Pie shows the percentage of the controls in the selected analysis that are represented by each control type displayed in the plot legend.
RD Questions Pie shows the percentage of the selected items that have a "Yes" answer to each risk discovery question displayed in the plot legend.
RD Ratings Pareto shows the risk discovery rating values of the items ranked from highest to lowest.
