Much of the case study's design is inherently determined for researchers, depending on the field from which they are working. In composition studies, researchers are typically working from a qualitative, descriptive standpoint. In contrast, physicists will approach their research from a more quantitative perspective. Still, in designing the study, researchers need to make explicit the questions to be explored and the theoretical perspective from which they will approach the case. The three most commonly adopted theories are listed below:
Individual Theories
These focus primarily on the individual development, cognitive behavior, personality, learning and disability, and interpersonal interactions of a particular subject.
Organizational Theories
These focus on bureaucracies, institutions, organizational structure and functions, or excellence in organizational performance.
Social Theories
These focus on urban development, group behavior, cultural institutions, or marketplace functions.
