“…The third data collection method that we have used is critical incidents. Besides its inductive nature (Edvardsson, Bo., 1992, in Gremler, DD, 2004), the critical incident method is recommended when the purpose of the research is to probe knowledge of less known subject (Gremler, DD, 2004). Thus, the critical incident technique is "a qualitative interview procedure which facilitates the investigation of occurrences (events, incidents, processes, issues) identified significant by the respondent and outcomes in terms of perceived effects" (Chell, E., 1998, in Chell, E. and Pittaway, L., 1998) More specifically, it is "a systematic process used to identify events or behaviors that lead to certain outcomes, such as success or failure in relation to specific tasks (Bitner and al., 1990), or satisfaction or dissatisfaction with a service" (Bitner and al., 1994), or as in our case "good or terrible shopping experiences" (Arnold and al., 2005).…”
