This document discusses case study research. It defines a case study as an in-depth analysis of a social unit such as an individual, group, or community to understand personal and hidden dimensions. Case studies use multiple sources of evidence and can be explanatory, exploratory, or descriptive in nature. They combine objective and subjective data and offer a comprehensive description while focusing narrowly. Steps in case study research include planning, developing instruments, collecting data, analyzing data, and disseminating findings. Benefits are an in-depth understanding of phenomena, while limitations include challenges in organization, analysis, and reporting findings.
