Case Studies
Case studies • To give unique understanding rather than form generalisations • Used for hypothesis development and the evolution of research questions • Prelude to a larger cross sectional study• Provide a flavour – in the form of vignettes
Four categories 1. To explain the causal links in reallife interventions – often too complex for more general approaches 2. To describe the context around the intervention 3. Illustrative – to give examples to others 4. To evaluate and intervention or practice
Case study types • Cases of individuals• Company• Supply chain• Customers• Market
Benchmarking • To compare with theory• To compare with best in class• Must establish measurement criteria
Methods • Multiple methods are used and multiple sources of evidence • Observation• Secondary data• Interviews• Internal surveys
Problems • Hard to generalise – so what is the value of case studies – too particular! • Hard to avoid researcher bias – often a participant • Hard to avoid unrepresentative subjects
Structure of a case study • Context/background – a rich description of what is going on. • Compare rich description with theory• Validate – analyse secondary sources – company annual reports etc. • Find out reasons – interviews with key participants • Find out ef ects – wider survey• Conclusions and evaluation
