This researcher’s training in systems analysis is adequate preparation for the project. Case studies tend to be selective, focusing on one or two issues that are fundamental to understanding the system being examined. Justifying such studies to more quantitatively minded researchers who may not be experienced with the domain under investigation may seem like an almost unsurmountable obstacle. Differences between the responses of the administrators and faculty were explored using cross tabulations. Correspondence regarding this article can be addressed to Dr. The scribe should record responses as they are being stated as this conveys the idea that they are interested in what the respondent is saying. It is typically a system of action rather than an individual or group of individuals.

In that way both the technical requirements and the informational needs are met. Stake argued for another approach centered on a more intuitive, empirically-grounded generalization. Operations Management Research, 6 , However, participant-observations can be biased as the investigator is not an independent party. The logic linking the data to the propositions should also ensure the correct type and amount of relevant information is collected. Cross tabulations were used to explore the differences in responses of the faculty by school. In recommending that a chain of evidence be maintained, Yin was providing an avenue for the researcher to increase the reliability of the study.

Trochim considered pattern-matching as one of the most desirable strategies for analysis. Topic coding pertains to issues that generally only become apparent during data analysis, Beekhuyzen et al.

To counter some of these concerns, authors are encouraged to report all potentially relevant facts and hypotheses Gerring, The remodified instruments were reviewed by Levy. European Journal introdkction Information Systems, 15 3 Journal of Operations Management, 20 5 Archival records could be useful in some studies since they include service records, maps, charts, lists of names, survey data, and even personal records such as diaries.

Observations may be targeted at s e. Rigor in information systems positivist case research: Original dependencies are represented in blue, suggested additions in red, and suggested deletions in gray. Introduction to Case Study. Modern semiotics, which studies the construction of meanings with respect to communication as telis as to the construction and maintenance of reality Beynon-Davies, ; Chandler,is based on the supposition that the whole of human experience is an interpretive activity mediated and sustained by signs Deely, Similar to interviews, having multiple investigators making the same observation may increase the reliability of the resulting evidence.

Such studies may also identify differences between individual cases with a view of potentially generating a classificatory framework Gerring, As the choice of the theoretical lens is entirely subjective, there are no explicit guidelines for how exactly this should be done Walsham, The intorduction of the research method is determined by several factors, including the type of research question, the control an investigator has over actual behavioural events, and the focus on contemporary as opposed to historical phenomena Yin, Qualitative case studies in operations management: Additionally, confirmations of counterintuitive predictions will be more convincing than confirmations of commonsensical predictions Campbell, The inappropriate manner of generalizing assumes that some sample of cases has been drawn from a larger universe of cases.


They utilise open-ended questions, thus allowing for even more flexibility. The appropriate number of interviews depends on the size of the unit of analysis e. In addition, the ability to search for disproving evidence may lead to a reduction in confirmation bias, and maintaining a chain of evidence allows for stronger justifications of any conclusions. What is happening at extremes? This means that the researcher considers not just the voice and perspective of the actors, but also of the relevant groups of actors and the interaction between them.
