Lets first understand what is Human Error. In my conversations and training sessions with various levels of experts in Aviation, I have received many answers to this question. It was a matter of great amazement, even shock, for me to realise that even aviation professionals with years of experience behind them were often not clear on what constitutes Human Error, why it occurs and how to manage it!
Quite Simply put, it is an imbalance between what the situation requires, what the person intends and what he/she does. It happens when a human:
- Plans to do right thing, but with wrong outcome.
- Does wrong thing for a situation.
- Fails to do anything when action is needed.
Human Factors are capable of circumventing even the most advanced safety devices. The reason for this is that human beings get used to the hazards over a period of time thus leading to similar types of accidents repeating at regular intervals. However, the preconditions to all these disasters can be traced back to identifiable organisational deficiencies.
It is important to note that while to err is human, to blame it on somebody else is even more human. Operational people do, and will continue to, make mistakes. What we need to do is to enhance systems tolerance to human failure.
As we proceed in this blog, we shall investigate the classifications of Human Error, many causes of Human Errors, and finally build up to techniques and methods we can employ to have a degree of control over errors our staff could make, make our organisations more resilient to those errors and even learn to identify those error causing conditions in ourselves and our colleagues.
