The Essential Factors model is an incident investigation model based on determining the essential and contributory factors that lead to an incident. An incident is viewed in terms of an interaction of essential and contributing factors that results in damage to people, property or production. An essential factor is one which when removed from, or added to, an incident sequence will interrupt that sequence. A contributing factor is one which increases the likelihood that the sequence of factors will continue but is not essential to the damage.
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.
All essential factors differ in controllability. Each essential factor, once identified is able to be reviewed for potential points of control. That is potential ways in which to reduce the risk of that incident re-occurring.
Famous quotes containing the words essential, factors and/or model:
“As liberty of thought is absolute, so is liberty of speech, which is “inseparable” from the liberty of thought. Liberty of speech, moreover, is essential not only for its own sake but for the sake of truth, which requires absolute liberty for the utterance of unpopular and even demonstrably false opinions.”
—Gertrude Himmelfarb (b. 1922)
“The goal of every culture is to decay through over-civilization; the factors of decadence,—luxury, scepticism, weariness and superstition,—are constant. The civilization of one epoch becomes the manure of the next.”
—Cyril Connolly (1903–1974)
“She represents the unavowed aspiration of the male human being, his potential infidelity—and infidelity of a very special kind, which would lead him to the opposite of his wife, to the “woman of wax” whom he could model at will, make and unmake in any way he wished, even unto death.”
—Marguerite Duras (b. 1914)
