Human may
be unpredictable, we also cause accidents. However, when doing research on ship
survivability I clearly see in my models the strength of humans in a system.
Things
happen; by chance, as a result of a threat or because somebody makes a mistake.
This has always been the case, is the case today and will always be the case.
When an
engineer looks at a system there is a drive for getting everything controllable
and predictable, these are considered important characteristics of a good
system. Therefore, people in that system will be considered a problem, because
they are not controllable nor predictable. However, recognizing the fact that
things will happen anyway you will also need a system that is able to
recover.
Nature (and
humans) are great at recovering from things unplanned for (machines can if they
are good recover from a limited set of problems and only if that problem is recognized
beforehand and a solution is prepared).
I think the
human errors are outweighed many times by the human recoveries and last minute prevention
skills and the “human prevention” events are probably many more than the “human
error” incidents. The problem is that no one is counting the human prevention
events, but when you need someone to blame you identify, document and count the
human errors.
GO HUMANS!
