Case Study Research is a qualitative research method that involves an in-depth investigation of a single case or a small number of cases. This approach allows researchers to explore complex issues in real-life contexts, providing detailed insights into specific phenomena. It often combines various data sources, such as interviews, observations, and documents, to create a comprehensive understanding of the case. This method is particularly useful in fields like social sciences, business, and healthcare, where understanding the nuances of a situation is crucial. By focusing on specific instances, case studies can reveal patterns, generate hypotheses, and inform practice or policy decisions.
