Ergonomics

Human factors (hereinafter, the Factors) is a set of human factors that, although may be originated from outside an individual, (a) depend on none, but this individual, and (b) impact this individual's work performance. Although groups and/or organizations may try to influence the Factors, they are not under their direct control.

Interactions

The Factors may impact four types of interactions:

1. People-and-people collaboration.
2. People-and-machines exchange.
3. People-and-procedures reaction.
4. People-and-environment cooperation.

(1)Understanding the maintenance operation as a system. An understandingof the systemic nature of the maintenance operation is vital to understanding how one’sindividual actions affect the whole organization. A person who understands the bigpicture is more apt to think things through before acting. Identifying and understanding basic Human Factors issues. BasicHuman Factors concepts are also taught in the course of MRM training. These conceptstypically include human perception and cognition, workplace and task design, groupbehavior (norms), and ergonomics. However, this list is far from exhaustive and theconcepts taught should be tailored to meet the needs of each particular audience.(3)Recognizing contributing causes to human errors. A basic primer onhuman error is a key component to MRM training. By understanding the interactionbetween organizational, work group, and individual factors that may lead to errors andaccidents, maintenance personnel can learn to prevent or manage them proactively in thefuture. Reason’s model provides a good foundation for human error theory; however,many other models of human error exist, such as the “Dirty Dozen” scenarios. These canalso be adapted for use in MRM training.
