human error mechanism?
-1 : It is analysis of an incident or accident which will
make it
possible to identify what error has been committed
and by
whom. It is the process whereby the perpetrator is
made
responsible which may lead to elimination of the
error.
-2 : If we have a better understanding of the cognitive
error
mechanism, it will be possible to adapt procedures,
aircraft
interfaces, etc.
-3 : It is error management procedure which enables us
to
continuously adjust our actions. The better we
understand the
underlying mechanism of an error, the better will be
our means
for detecting and adapting future errors.
-4 : Since error is essentially human, once it has been
identified by
the use of procedures, a person will be able to
anticipate and
deal with it automatically in the future.
