Editing Causes

You can edit the failure causes of your system.

This task shows you how to:

Before you begin: Select a failure mode in the corresponding cell of a causality relationship. For more information, see Editing or Selecting a Failure Mode.

Edit Causes for DFMEA

You can edit the causes for a Design FMEA.

In the following scenario, the system corresponds to a logical system. The behavior is the same for other systems.

  1. To edit a cause, click a failure cause cell.
    The corresponding elements are displayed as follows:
    • A tree per logical component that is a descendant of the system analyzed by the current FMEA.
    • As children of components, the functions implemented by these components in the context of the parent system.
    • As children of functions or components, the associated failure modes already defined for each logical component or function.


  2. To define a failure cause, from the trees, you can either:
    • Select an existing failure mode or any other RAMS analysis.
    • Select a logical component or its function, and then enter a name to create a new failure mode.
      Note: If you select Confirm failure mode creation in the widget preferences, the Create Failure Mode for xxx dialog box enables you to:
      • Enter the failure mode name.
      • Select a customized type, if any.
      For more information, see Customizing Preferences.
    A new failure mode is created and associated with the logical component or function implemented in context by the logical component. The failure mode and its architectural context appear in a tile in the cell.
  3. Optional: To edit several causes for a function, create another causality relationship with the same function and the same failure mode, and then repeat steps 1 and 2.

Edit Causes for PFMEA

You can edit the causes for a Process FMEA.

  1. To edit a cause, click a failure cause cell.
    The corresponding elements are displayed as follows:
    • A tree for resources (if any).
    • A tree for manufactured items (if any).
  2. To define a failure cause, from the trees, you can either:
    • Select an existing failure mode or any other RAMS analysis.
    • Select a cause in the MBOM items that are inputs of the operation and the resources used by the operation, and then enter a name to create a new failure mode.
      Note: If you select Confirm failure mode creation in the widget preferences, the Create Failure Mode for xxx dialog box enables you to:
      • Enter the failure mode name.
      • Select a customized type, if any.
      For more information, see Customizing Preferences.
    A new failure mode is created and associated with the MBOM item. The failure mode and its architectural context appear in a tile in the cell.
  3. Optional: To edit several causes for an operation, create another causality relationship with the same operation and the same failure mode, and then repeat steps 1 and 2.
