Often the effects of a failure mode may be easy to detect,
and our equipment can react by raising an alarm or compensating for the resulting fault.

%
Some failure modes may cause undetectable failures, for instance a component that causes
a measured reading to change could have adverse consequences yet not be flagged as a failure.
