Case studies require the participant to analyse large amounts of data that describe the current structure and situation of a fictious enterprise. The participant's task is to understand the issues and come up with proposals or recommendations. Usually, case studies are written tests. Sometimes, the participant has to present his/her proposals to the assessors and justify them.
Depending on the content of the case study, different criteria are assessed. There are case studies meant for assessing the social and leadership skills, but also such aiming at assessing expertise management knowledge. Often case studies are computer-based exercises.
