Five Analytic techniques
Pattern Matching
· One of the most desirable techniques
· Compares an empirically based pattern with a predicted one (or with several alternative predictions)
· If the patterns coincide the results can help a case study to strengthen internal validity
· Nonequivalent dependent variables as a pattern
o According to this design, an experiment may have multiple dependent variables-that is a variety of relevant outcomes
o If, for each outcome, the initially predicted values have been found, and at the same time alternative “patterns” of predicted values (including those deriving from methodological artifacts or “threats” to validity) have not been found, strong causal inference can be made.
Explanation Building
Time-Series analysis
The essential logic underlying a time-series design is the match between the observed (empirical) trend and either of the following (a) a theoretically significant trend specified before the onset of the investigation or (b) some rival trend, also specified earlier.
Logic models
Deliberately stipulates a complex chain of events over an extended period of time. The events are staged in repeated cause-effect-cause-effect patterns, whereby a dependent variable (event) at an earlier stage becomes the independent variable (causal event for the next stage.
The process can help a group define more clearly its vision and goals, as well as how the sequence of programmatic action will (in theory) accomplish the goals.
Individual-level logic model
Firm or organizational level logic model
An alternative configuration for an organizational level logic model
Program level logic model
Cross-Case Synthesis
Applies specifically to the analysis of multiple cases
The technique treats each individual case study as a separate study
One possibility starts with the creation of word tables that display the data from the individual cases according to some uniform framework.
Now the analysis can start to probe whether different group of cases appear to share some similarity and deserve to be considered instances of the same type of general case. Such an observation can further lead to analyzing whether the arrayed case studies reflect subgroups or categories of general cases—raising the possibility of a typology of individual cases that can be highly insightful.
Chapter 6 Reporting Case Studies; How and What to Compose
Orienting the Case Study Report to an Audience’s Needs
For dissertation committee-under these conditions, should attempt to communicate directly with this committee. A recommended tactic is to integrate the committee member’s previous research into the thesis or dissertations, creating greater conceptual (and methodological) overlap and thereby increasing the thesis or dissertation’s potential communicability to that particular audience.
Whatever the audience, the greatest error you can make is to compose a report from an egocentric perspective.
Formats for Written Case Study Reports
Among written forms of case studies, there are at least four important varieties. The first is the classic single-case study.
A second type of written product is the multiple-case version of the classic single cae. This type of multiple-case report will contain multiple narratives, covering each of the cases singly, usually presented as a separate chapters or sections. Your report also will contain a chapter or section covering the cross-cae analysis and result.
A third type of written product covers either a multiple or a single case study but does not contain the traditional narrative. Instead the composition for each case follows a series of quetios and answers based on the questions and answers in the case study database.
The fourth and last type of written product applies to multiple-case studies only. In this situation, there may be no separate chapters or sections devoted the individual cases.
Rather, your entire report may consist of the cross-case analysis, whether purely descriptive or also covering explanatory topics. In such a report, each chapter or section would be devoted to a separate cross-case issue, and the information from the individual cases would be dispersed throughout each chapter or section.
Six illustrative structures-
Linear-Analytic Structures-This is a standard approach for composing research reports.
Comparative Structures-
A comparative structure repeat the same case study two or more times, comparing alternative descriptions or explanations of the same case.
Chronological Structures-Because case studies generally cover events over time, a third type of approach is to present the case study evidence in chronological order.
Theory-Building Structures-chapters or sections follow some theory-building logic.
Suspense Structures-Inverts the linear-analytic structure
Unsequenced Structures-one can change the order the chapters and not alter its descriptive value
Procedures In Doing Case Study Report
When and How to Start Composing
After the literature ha been reviewed and the case study has been designed, two sections of a case study report can be drafted: the bibliography and the methodological section.
A third section is the preliminary literature review and how it led to or complemented yur research questions and the propositions being studied.
After data collection but before analysis begins, a fourth section that can be composed covers the descriptive data about the cases being studied.
If you can draft these four sections before analysis has been completed, you will have made a major advance.
