Case studies should illustrate key themes and concepts, providing insights into real-world applications of governance and administration. Moreover, candidates should evaluate the diversity of issues represented—ensuring a mix covering social, economic, and environmental aspects. Finally, the clarity and availability of data in the case studies are crucial for thorough analysis and discussion, making them effective learning tools.
