A vital system design principle that may

be applied to either hardware or

software.

In each case, the vital

function is performed by two or more

independent subsystems, each of which

is independently capable of enforcing a

safe reaction as well as periodically

checking the other subsystem(s).

The

checks normally include verification that

checks are performed and that the

interval between checks is short enough

to reduce, to an acceptable level,

hazards caused by multiple failures.
