In a case competition, participants strive to develop the best solution to a business or education-related case study within an allocated time frame, typically with teams of two or more individuals pitted against each other in a head-to-head or broader relative ranking. Teams deliver presentations for judges and, while competitions vary in composition, a standard format and purpose exists. In terms of cumulative number of participants, the HSBC/HKU Asia Pacific Business Case Competition is the world's largest case competition, with over 130,000 participants since 2008.
