External validity reflects whether or not findings are generalizable beyond the immediate case or cases; the more variations in places, people, and procedures a case study can withstand and still yield the same findings, the more external validity.
Yin defines the case study research method as an empirical inquiry that investigates a contemporary phenomenon within its real-life context; when the boundaries between phenomenon and context are not clearly evident; and in which multiple sources of evidence are used Yin,p.
Yin have written about case study research and suggested techniques for organizing and conducting the research successfully.
Social science research and decision-making. The researcher must use the designated data gathering tools systematically and properly in collecting the evidence. Why do non-profit organization participants use the network? After investigators are trained, the final advance preparation step is to select a pilot site and conduct a pilot test using each data gathering method so that problematic areas can be uncovered and corrected.
In this case, the researcher is primarily interested in determining whether or not the electronic community network is beneficial in some way to non-profit organization participants. Exemplary case studies will deliberately sort the data in many different ways to expose or create new insights and will deliberately look for conflicting data to disconfirm the analysis.
This type of case study involves two levels of analysis and increases the complexity and amount of data to be gathered and analyzed.
Collect Data in the Field The researcher must collect and store multiple sources of evidence comprehensively and systematically, in formats that can be referenced and sorted so that converging lines of inquiry and patterns can be uncovered.
Reports on case studies from many disciplines are widely available in the literature. Careful definition of the questions at the start pinpoints where to look for evidence and helps determine the methods of analysis to be used in the study.
One researcher then examines the data of that type thoroughly.
The investigator reviews the purpose of the study with the entire Board, schedules individual interview times with as many Board members as can cooperate, confirms key contact data, and requests that all Board members respond to the written survey which will be mailed later.
As patterns begin to emerge, certain evidence may stand out as being in conflict with the patterns. Library goals as responses to structural milieu requirements: The report also includes confirming and conflicting findings from literature reviews. Throughout the evaluation and analysis process, the researcher remains open to new opportunities and insights.
Unpublished doctoral dissertation, University of Massachusetts, Amherst. Some researchers report the case study as a story. At the outset of the design phase, the researcher determines that only one of these networks will be studied and further sets the study boundaries to include only some of the non-profit organizations represented on that one network.
The case study method is applicable to this set of users because it can be used to examine the issue of whether or not the electronic community network is beneficial in some way to the organization and what those benefits might be.
Unpublished doctoral dissertation, Columbia University, New York. For example, a case study may involve study of a single industry and a firm participating in that industry. The researcher strives to establish a chain of evidence forward and backward.
