This article describes an effective approach to using the Enhanced Critical Incident Technique (ECIT) research method based on Flanagan's (1954) Critical Incident Technique (CIT). It begins with an overview of the CIT, how to decide if it is the appropriate methodology to use, then, using a recent CIT study as an example, discusses Flanagan's five steps for conducting a CIT study: (a) determining the activity's aim; (b) setting plans, specifications, and criteria for the information to be obtained; (c) collecting data; (d) analyzing the data; and (e) reporting the findings. Nine credibility checks, developed to increase the rigour and credibility of the ECIT, are described.
