Critical Incident Technique - History

History

The studies of Sir Francis Galton (circa 1930) are said to have laid the foundation for the Critical Incident Technique, but it is the work of Colonel John C. Flanagan, that resulted in the present form of CIT (described in Psychological Bulletin, Vol. 51, No. 4, July 1954). Flanagan defined the Critical Incident Technique as: set of procedures for collecting direct observations of human behaviour in such a way as to facilitate their potential usefulness in solving practical problems and developing broad psychological principles . . . By an incident is meant any specifiable human activity that is sufficiently complete in itself to permit inferences and predictions to be made about the person performing the act. To be critical the incident must occur in a situation where the purpose or intent of the act seems fairly clear to the observer and where its consequences are sufficiently definite to leave little doubt concerning its effects. (Flanagan, 1954:327)

Flanagan's work was carried out as part of the Aviation Psychology Program of the United States Army Air Forces during World War II, where Flanagan conducted a series of studies focused on differentiating effective and ineffective work behaviors. Since then CIT has spread as a method to identify job requirements, develop recommendations for effective practices, and determine competencies for a vast number of professionals in various disciplines. In particular, it has been used in service research.
