A checklist provides a frame work and initiates brief discussion about the case, expected difficulties and plan of action to deal with complication or difficult situations.
In the previous article, we discussed about human factors as one of the most important reasons for errors. An individual is aware of his/her immediate surroundings but not about the larger surroundings. This is called as “situational awareness”.
A person may do his/her job diligently, but when it comes to synchronous activity of different departments or different persons there is always a potential for error. When two people with different background information start functioning together, there is bound to be a gap. When few actions, having no logical sequence, have to be done in synchronized manners, the chance of something getting missed is high. Think of a memory test where few different objects are flashed in front of you and you are asked to memories them. It is a high possibility that you may forget some of them, if not, you will not recollect them in the same order!
When checklists come into play
Checklists find their way in such situations. Actually checklist is not a new concept at all. Do we not make a “To Do list”? However, the institutionalization of the checklist has an interesting history. In 1935, U.S. Military had organized an exhibition cum-competition for aircraft manufacturers. Boeing, the famous aircraft manufacturer was also in the competition. Model 299 of Boeing was very advanced and could carry five times more bombs than expected by the US military. The competition was a mere formality by Boeing. Major Hill, a very experienced pilot and trainer was given the job to fly the aircraft on that day. Model 299 took off smartly. The aircraft reached the height of around 300 feet height and suddenly tilted to one side. Within few seconds it collapsed to the ground and caught fire. Major Hill lost his life. After this unexpected accident, a fact finding committee was constituted. The committee concluded that there was no technical fault in the aircraft. The pilot was at fault! How could an experienced pilot commit such a blunder? That took a blunder that could cost his own life? Later, it was realized that the systems of the aircraft were quite complicated. Actually, the pilot was supposed to perform a number of tasks within a small period of time in a synchronous manner. And Major Hill had simply forgotten to perform one out of them! Continue reading
