Les Bell, another ex-pat Brit who lives in Australia was discussing the importance of training and reinforcement in such matters as DR/BCP. Les is also a pilot and so many of his analogies and examples have to do with piloting and aircraft.
Part of our discussion has a much wider scope.
Les had said:
"People under extreme stress may behave unpredictably and have limited capacity for rational thought"
This is the basis of much of pilot training, particularly in simulators, where procedures that are too dangerous to be attempted in a real aircraft can be repeated until drills are automatic.
Don't quote me on this, but I seem to recall reading in an aviation safety-related article that in an emergency, something like 50% of people lose it to the extent that they are completely unable to cope, 25% are capable of functioning with some degree of impairment, and 25% of people are able to complete required tasks correctly. Training by means of drills and rehearsals is able to correct that situation to a considerable extent.
Therefore in BCP/DRP planning, it's important to - as far as possible - simulate an emergency, rather than just story-boarding it, or doing a whiteboard walkthrough. Hence the requirement for fire drills, evacuation drills and the like; repetition conditions the mind to perform the task correctly under stressful conditions.
Most of us don't get the chance to do a full interruption test for our DRP, but the closer we can get, the better.
Training - drill and reinforcement so that you can carry out the actions automatically even when extreme stress has completely blanked and cognitive functions - is an important part of military "boot camp" training and one reason I find it so comical that CISSP course training gets called "boot camp".
Les is quite right. For a variety of reasons most people "loose it" under extreme stress. This is why military heroes, people who can hang in there and think clearly and make critical decisions, are held in such esteem. Similarly test pilots (and those test pilots who became the early astronauts). Having lightening fast reactions (racing drivers) and being in top physical condition helps, but there is something more.
Some authorities look to the old American 'gunslingers' and speculate about how the adrenaline rush in such situations is handled by the body and the brain. Typically all that adrenaline pumps up the muscles for "fight or flight" and in such panic or near panic situations rationality is not the key issue. But if we shift from the evolutionary context to the 'gunslinger', standing still means that there is a lot of 'shakes'. Being able to stay calm and not have the shakes leads to being a sucesfull 'gunslinger'. Evolution in action?
There are other forms of stress as well. I've seen sysadmins who have been up for more than 30 hours trying in futile to solve a problem that to me, well rested, is simple and obvious.
The lesson here is two-fold. The first is the point that Les makes. Train and reinforce.
The second is that when the disaster does strike be aware that the stress will load up on fatigue and that stressed and fatigued people do not make good decisions. Rest, shifts, alternates, standard plans and scenarios that can work to relieve the stress are important.
Les went on to point out:
Poor decision-making is the reason why extensive planning is so important.
These points are borne out in a recently-released book which makes fascinating reading:
"The Unthinkable: Who Survives When Disaster Strikes - and Why" by Amanda Ripley.
The book interviews survivors of 9/11, the Air Florida Potomac River crash, and others. It's amazing how many attribute their survival to military training and the positive, "get on with it", attitude that ingrains.
