Case studies help us to better understand, document, and describe our outcomes and results—both positive and negative. For each case study, we hope to gain an understanding of a key policy or program change and the advocacy efforts that led to the change. Target audiences for your case study may range from the non- technical (such as government officials or policymakers) to the technical (such as family planning advocates in other settings). Balancing the needs of both readers— for a compelling human interest narrative and for simple yet robust explanations of your methods and results—will strengthen your case study.
