Research to prepare case studies relevant to UPSC should focus on contemporary issues, policies, and their impact on society. Analyzing government initiatives, such as the Digital India campaign or the Swachh Bharat Mission, helps candidates understand the implementation and outcomes of public policies. Exploring historical case studies can also provide insights into governance challenges and solutions. It is beneficial to connect theoretical knowledge with practical examples, creating a comprehensive understanding of governance dynamics. Finally, reviewing reports from organizations like the Planning Commission or Niti Aayog can offer valuable data for analysis.
