A case study is a detailed examination of a specific instance or example, often used in research and education. It allows researchers to explore complex issues in real-life contexts, providing insights that can be applied to similar situations. For example, a business case study might analyze how a company like Apple successfully launched a new product, highlighting strategies and outcomes. In academic settings, case studies help students understand theoretical concepts by applying them to practical scenarios. This method encourages critical thinking and problem-solving skills. For instance, a medical case study could focus on a unique patient situation, helping future doctors learn how to approach similar cases in their practice.
