MBA students at a number of business schools primarily use the case method in their courses. Students receive cases - a type of written overview of a business-related scenario or quandary - and are then asked to play the role of decision-maker. By performing analyses and discussing root causes with their peers, MBA students can use their knowledge of economic and systems theories to determine ideal courses of action.
