Convergent

Coming together, meeting or joining. e.g. 2 leading to 1.

Dead ends

A line of logic which ends before a Root Cause is reached. This will be because it's a perfectly normal occurrence, or something you can do nothing about. e.g. train on normal journey or a weather issue. In French - cul de sac. We show this in the RCA diagram by closing off the Post-it with a solid underline.

Divergent

Branching out. e.g. 1 leading to 2.

Hazard

Something with the potential to cause harm or damage.

Immediate Causes

The conditions or events which were the direct cause of the incident.

Implied Verb

A verb which is not present (hidden) in a sentence but which is taken to be present. e.g. 'Brakes off' implies that 'The brakes were off'.

Incident

An event which caused, or could have caused, damage or harm to people, the environment, equipment, process or reputation.

Incident Statement

A short description of an incident which summarises 'What happened', 'The Consequences' and the 'Potential Consequence'.

Logic Flow Diagram

A diagram where each step is linked with another in a sensible and sequential way.

Potential Consequences

This is a short statement of what might have happened, which adds gravity to the investigation.

Risk

Interaction with a hazard, e.g. A busy road is a 'hazard', crossing it is a 'risk'.

Underlying Causes

The general conditions and failures which contributed to the incident.

Verb

An action word which should be used in all RCA Post-its to ensure that a question can be asked. e.g. 'Communication' on its own means very little. 'There were communication failures' means a lot more and we can ask 'Why were there communication failures?'
