The critical incident technique (or CIT) is a set of procedures used for collecting direct observations of human behavior that have critical significance and meet methodically defined criteria. These observations are then kept track of as incidents, which are then used to solve practical problems and develop broad psychological principles. A critical incident can be described as one that makes a contribution—either positively or negatively—to an activity or phenomenon. Critical incidents can be gathered in various ways, but typically respondents are asked to tell a story about an experience they have had. CIT is a flexible method that usually relies on five major areas. The first is determining and reviewing the incident, then fact-finding, which involves collecting the details of the incident from the participants. When all of the facts are collected, the next step is to identify the issues. Afterwards a decision can be made on how to resolve the issues based on various possible solutions. The final and most important aspect is the evaluation, which will determine if the solution that was selected will solve the root cause of the situation and will cause no further problems. History The studies of Sir Francis Galton 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. Flanagan defined the critical incident technique as: 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. Flanagan went on to found American Institutes for Research continuing to use the critical incident technique in a variety of research. 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. Principal uses CIT can be used in training, systems design and accident investigation. It is an integral part of large scale task analysis. It identifies the most costly happenings in a complex environment where people and machines work as a system. Its origin in investigating pilot errors in wartime,328 et seq and other life-and-death situations, means it identifies top priorities in a man-machine system or other complex action-oriented situation.
