According to Creswell (2009), the empirical inquiry collects data from multiple sources and examines them in detail over a period of time. The main purpose of a case study is to gain an in-depth understanding of the study’s process and outcome. Therefore, a researcher uses four factors: creates research questions, investigates tactics, sets up variables, and predicts an outcome. There are three types of case studies: (a) an instrumental case study focuses on the general aspects of the case; (b) an intrinsic case study focuses on understanding the details of the case; and (c) a collective case study which allows a researcher to compare multiple cases within a single research (Stake, 1995).
