Case study is a qualitative method that usually consists of a way of deepening an individual unit. It serves to answer questions that the researcher does not have much control over the phenomenon studied.
The case study contributes to a better understanding of the individual phenomena, the organizational and political processes of society. It is a tool used to understand the form and motives that led to a particular decision.
Using the case study, Sigmund Freud developed his theory of human personality by conducting detailed interviews over a long period of time with some clients.
