A case study is an appropriate research design when you want to gain concrete, contextual, in-depth knowledge about a specific real-world subject. It allows you to explore the key characteristics, meanings, and implications of the case. Researchers often use case studies in the exploratory phase of research to gather qualitative data. They can also be used to create, support, or refute hypotheses and guide future research. For instance, a marketing professional might conduct a case study to discover why a viral ad campaign was so successful. If you’re considering a case study, follow these steps:
