A failure hierarchy consists of a top-level failure class
and several lower levels of failure codes.
About this task
Typical failure codes are Problem, Cause, and Remedy. Each
cause in a hierarchy can have multiple problems. Each problem can
have multiple remedies. Navigating the failure hierarchy lets you
view the problems that are associated with certain causes, and which
causes are associated with specific remedies within a hierarchy. Navigating
the hierarchy also lets you identify the problem for which you want
to add a cause or a remedy.
