A case study is an in-depth, up-close and comprehensive analysis of a topic and its related background conditions. It could be examination of a person, group, community or event. A case study is a technique of research that defines situations rather than modeling causal relations. It illustrates an occurrence comparing to an ideal definition. It’s simpler to handle descriptive work than causal suggestions while working in a case study method. Secondly, a case study is better when the purpose contemplates the depth over width in research. Case study best offers a depth examination of phenomena. An empirical case study is explicitly based on observation and experimentation.
