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:
“I am not so foolish as to declaim against forms. Forms are as essential as bodies; but to exalt particular forms, to adhere to one form a moment after it is outgrown, is unreasonable, and it is alien to the spirit of Christ.”
—Ralph Waldo Emerson (1803–1882)
“I always knew I wanted to be somebody. I think that’s where it begins. People decide, “I want to be somebody. I want to make a contribution. I want to leave my mark here.” Then different factors contribute to how you will do that.”
—Faith Ringgold (b. 1934)
“...that absolutely everything beloved and cherished of the bourgeoisie, the conservative, the cowardly, and the impotent—the State, family life, secular art and science—was consciously or unconsciously hostile to the religious idea, to the Church, whose innate tendency and permanent aim was the dissolution of all existing worldly orders, and the reconstitution of society after the model of the ideal, the communistic City of God.”
—Thomas Mann (1875–1955)
