        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
       Targeting CS Reports
• Audience
  – Academia
  – Popular science
  – Thesis committees
  – Research funders
• Different versions of report
• Avoid egocentric perspective
  – Understand audiences and their needs
          Report Formats
    - Classic Single-Case Study
• Narrative
• Augment using
  – Tabular
  – Pictorial displays
• Typically Book-sized
          Report Formats
       - Multiple-Case Studies
• A set of narrative single CSs
• One CS/chapter
• One [several] cross-case chapter[s]
           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
              Report Formats
           - Cross-Case Report
•   Not narrative
•   Multiple case-studies only
•   Cases intertwined in all chapters
•   One Chapter/CS-topic
         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”
    Illustrative Structures for CS
• 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
    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
     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???
     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
   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
          Suspense Structures
•   Present the outcome of the study first
•   Reveal evidence afterwards
•   The inverse of linear analytical structures
•   Suitable for explanatory studies
     Unsequenced Structures
• The ordering of the sections or chapters is
  not important
• Suitable for descriptive studies
 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
  – Also review by case study subjects
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
