Adding an FMEA

FMEA Hierarchy View

To view the FMEA in a hierarchical format, click the Hierarchy tab at the bottom of the Analysis panel.

This view, which is the default view of the FMEA analysis, displays the records defined in your analysis (e.g., functions, failures, etc.) at-a-glance in a hierarchical tree structure.

Note: The following image shows the default, Effects Before Causes, FMEA structure. The display will vary if you have selected one of the other FMEA structures.

Using the FMEA Hierarchy View

The FMEA hierarchy view allows you to add, insert, edit, copy and paste the records in your analysis. You cannot edit text directly in this view. Instead, all editing in this view is done via properties windows that you can access by double-clicking a row in the hierarchy or by right-clicking a row and choosing Edit from the shortcut menu.

You can move the records in the FMEA hierarchy view up and down either by dragging them to the desired location or by using the Up and Down icons on the Home tab of the Ribbon.

  

These commands move the selected record down or up the list of records of the same type that are associated with the same record (e.g., move a failure up or down within the list of failures that have been defined for the same function).

Available Columns

To hide or display columns, right-click the column headers in the FMEA hierarchy view, then click Customize Columns to select which columns you want to display. These settings are stored per computer/username in the FMEA Hierarchy page of the Application Setup, so any project that you open on this computer will have the same columns displayed.

The available columns include the following:

For example, you might have a failure mode called "Bulb failed" that has two causes, "Filament burned" and "Shattered." Assume you are basing failures on XFRACAS incidents. If there are 3 incidents in XFRACAS with the "Bulb failed - Filament burned" combination and 2 incidents with the "Bulb failed - Shattered" combination, then the Observed Occurrences column will display a value of 5 for the "Bulb failed" failure, a value of 3 for the "Filament burned" cause and a value of 2 for the "Shattered" cause.

There are also 16 columns that can be enabled to display RPN ratings and/or metrics. Each column will be displayed only if it has been selected in the Customize Columns window and is enabled in the interface style for the particular project. The lowercase letter "i" indicates an initial rating or metric while the letter "r" indicates a revised rating or metric.

You also can use the Highlight Priority command to highlight the records in the FMEA hierarchy view based on the risk assessment ratings. Choose FMEA > Tools > Highlight Priority to toggle the priority highlights on and off. For more information about how to setup the priority highlights, refer to the Displaying RPN Metrics in the Analysis Panel topic.
