A.1 DESIGN OF THE CASE STUDY

1. What is the case and its units of analysis?
2. Are clear objectives, preliminary research questions, hypotheses (if any) defined in advance?
3. Is the theoretical basis—relation to existing literature or other cases—defined?
4. Are the authors? intentions with the research made clear?
5. Is the case adequately defined (size, domain, process, subjects?)?
6. Is a cause-effect relation under study? If yes, is it possible to distinguish the cause from other factors using the proposed design?
7. Does the design involve data from multiple sources (data triangulation), using multiple methods (method triangulation)?
8. Is there a rationale behind the selection of subjects, roles, artifacts, viewpoints, and so on?
9. Is the specified case relevant to validly address the research questions (construct validity)?
