In-depth, detailed examination of a particular case
A case study is an in-depth, detailed examination of a particular case (or cases) within a real-world context.[1][2] For example, case studies in medicine may focus on an individual patient or ailment; case studies in business might cover a particular firm's strategy or a broader market; similarly, case studies in politics can range from a narrow happening over time like the operations of a specific political campaign, to an enormous undertaking like world war, or more often the policy analysis of real-world problems affecting multiple stakeholders.
Generally, a case study can highlight nearly any individual, group, organization, event, belief system, or action. A case study does not necessarily have to be one observation (N=1), but may include many observations (one or multiple individuals and entities across multiple time periods, all within the same case study).[3][4][5][6] Research projects involving numerous cases are frequently called cross-case research, whereas a study of a single case is called within-case research.[5][7]
