Failure effect causes are defined to indicate the specific event(s) that can cause a given failure effect to occur. For object failure effects, the causes are a list of the specific failure modes that result in that effect. For design failure effects, the cause list is comprised of object failure effects. Failure effect causes can be defined using the Failure Effects panel (for object effects) or the Design Failure Effects panel (for design effects).
Choose the Failure Effects tab within the context panels.

Click on the "Causes" button to the right of the grid.
5
Click on the base node that is either called "Combined Effect" or "Undefined Cause" (depending on if there are already causes or not), then press the plus icon at the right edge of the panel.

In the dialog that appears, highlight the causes to be added and press the Select button.
