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, Effect Severity Pareto, Cause Occurrence Pareto and Cause Detection Pareto show the applicable values ranked from highest to lowest. You can view the initial values only, the revised 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, Cause Occurrence Pie and Cause Detection Pie show the percentage of the effects or causes in the selected analysis that are represented by the rating value displayed in the plot legend. You can view the initial values or the revised values.

• Classification Pie shows the percentage of the causes in the selected analysis that are represented by each special design manufacturing characteristic 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, Action Category Pie and Action Priority Pie show the percentage of the actions in the selected analysis that are represented by each type 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.
