Every incident has essential factors associated with people, equipment and environment giving the 100% paradigm:
100% / 100% / 100% paradigm –
- 100% of incidents include “people” factors
- 100% of incidents include “equipment” factors
- 100% of incidents include “environment” factors
It is the purpose of the Essential Factors model to attempt to use value-neutral language to give maximum “meaning” and minimum “affect”. This will not always be the case but it is suggested that the use of the word “cause” and “human error” by an accident investigator during data collection and interview phases, will have a potentially greater negative response than the use of alternative words.
