1 Reporting Case-Studies Chapter VI Dag Nyström Frank Lüders

2 Case-Study Reports Compose report (format) early in CS –Select form at design time Wider audience Often comprehensive –”Book-sized” –Part of multi-method studies

3 Targeting CS Reports Audience –Academia –Popular science –Thesis committees –Research funders Different versions of report Avoid egocentric perspectiveAvoid egocentric perspective –Understand audiences and their needs

4 Report Formats - Classic Single-Case Study Narrative Augment using –Tabular –Pictorial displays Typically Book-sized

5 Report Formats - Multiple-Case Studies A set of narrative single CSs One CS/chapter One [several] cross-case chapter[s]

6 Report Formats - Questions & Answers Not narrative Single/multiple case-studies Questions based on DB questions –Shortened and edited Easier to write –Avoid writers cramp Reader can draw direct conclusions

7 Report Formats - Cross-Case Report Not narrative Multiple case-studies only Cases intertwined in all chapters One Chapter/CS-topic

8 CS Reports as Part of Multi Method Studies CS encompasses other methods –Typically chapter in large study In overall conclusions: –CS strengthen evidence from other methods Triangulation CS share the same research questions –“Independent studies show the same result”

9 Illustrative Structures for CS Compositions Six types of structures –Linear analytic structures –Comparative structures –Chronological structures –Theory-building structures –Suspense structures –Unsequenced structures All may be used for multiple- or single- case studies

10 Linear Analytic Structures The classical approach for composing research reports –Problem formulation –Relevant prior literature –Methods used –Findings –Conclusions Suitable for all types of case studies –Explanatory, descriptive, or exploratory

11 Comparative Structures Repeat the same study two or more times –From different perspectives –Using different descriptive/explanatory models An example of pattern-matching at work Suitable for –Explanatory and descriptive studies –Not Exploratory???

12 Chronological Structures Present evidence in chronological order Sections represent phases of the study Suitable for explanatory case studies –Explain = show causal relationships –A cause always occurs before an effect –Maybe also descriptive and exploratory??? Pitfall: overemphasize early phases –Advisable to draft report backward

13 Theory-Building Structures Sequence of chapters follows some theory-building logic May produce very compelling arguments Suitable for –Explanatory studies: build causal arguments –Exploratory: debate the value of further investigating hypotheses and propositions

14 Suspense Structures Present the outcome of the study first Reveal evidence afterwards The inverse of linear analytical structures Suitable for explanatory studies

15 Unsequenced Structures The ordering of the sections or chapters is not important Suitable for descriptive studies

16 Procedures in Doing a CS Report When and how to start composing? –You cannot start composing early enough Case identities: Real or anonymous? –Avoid anonymity as much as possible Review of the draft CS: A validating procedure –Also review by case study subjects

17 What Makes an Exemplary CS? The case study must –be significant –be “complete” –consider alternative perspective –display sufficient evidence –be composed in an engaging manner
