Failure modes
Recent studies classified
failure modes and proposed new concepts
and principles for
engineering resilient
systems (for example,
Hollnagel et al .). Most notable is Leveson's
STAMP paradigm.
Failure modes are associated with the
failure model ... The model proposes three primary sources for operational failure:
- Failure to prevent an exceptional event, such as a
hardware fault or an unintentional
operator's action, which results in exceptional operational conditions
- Failure to return the
system from the exceptional condition back to normal operation
- Failure to protect the
system from events that do not suite the exceptional condition.
