The workbook will help implementers identify existing and planned data sources; prioritize evaluation research questions; and determine the roles, responsibilities, and timelines for answering the research questions. The process of developing an evaluation plan in cooperation with a group of stakeholders will foster collaboration, shared purpose, and transparency, thereby ensuring that stakeholders agree on the purpose and use of the evaluation’s findings. A plan also deflects wasted effort and ensures that information is available to answer the agreed-upon questions.
