What Is the Meaning of Situational Awareness?

Situational awareness means knowing what is going on around you, understanding what it means, and being able to predict what is likely to happen next.

It is the difference between spotting a problem early and being caught out by it.

The most widely used definition comes from human factors researcher Mica Endsley, who described it in three levels:

1. Perception - picking up the relevant details: who is around, how they are behaving, where the exits are.
2. Comprehension - working out what those details mean. A raised voice in a GP waiting room means something different from a raised voice at a football match.
3. Projection - anticipating where things are heading, so you can act before the situation develops.

The term started in military aviation. It is now used in healthcare, policing, transport and security, and anywhere else a missed cue can lead to harm.

At work, good situational awareness is what lets staff notice the early signs of aggression and step in while there is still time to calm things down. It is a core part of our Conflict Management & Personal Safety course and the starting point for our de-escalation training.
