A case study refers to an approach to research that centers on obtaining an in-depth understanding of a certain event or entity at a given time. Therefore, it is not characterized by the methods utilized in the collection or analysis of data, but rather it focuses on a certain unit of analysis. It is this unit that is referred o as the case. However, what forms a case is not laid out clearly.
Normally, case studies are bound in some discrete way by scrutinizing or studying a precise or specific set of events, organizations, departments, schools, or individuals. The nuisance of what makes a case good or what does not is often contested and from time to time subtle. For instance, the topic of a case study can be an individual, but not the means by which that particular individual engages in a certain practice. An example is a doctor. A doctor can be a case, but the practice of doctoring probably has no specificity or the boundedness to be considered a case.
A case study is a mean of presenting data that has been gathered through various means that include, but not limited to observations, videotaping or recording, interviews as well as document collections. It is also a study that uses data that have been collected through a variety of means to enhance the theory generating capabilities of a case study and to offer validity of the assertions made by the researcher or by the individuals in the case.
Some people also refer to a case study as an account of an event or activity or a problem that have a real or a hypothetical situation and comprises complexities that could be encountered in real life or a workplace. Therefore, it is a study that helps one in visualizing how the real life complexities help in or influence the decision making.
Therefore, analyzing a case study required that an individual practices how to apply his or her knowledge and thinking to a real life scenario. To learn from a case study, an individual will be analyzing, putting knowledge into application, reasoning or thinking critically and drawing conclusions. Therefore, the main objective of a case study is to examine events, situations are individuals and document or draw conclusions from the analysis that has been made. It is particularly considered very useful when trying to test the theoretical models by utilizing them in a real world condition.
