What does evaluation design refer to?

Evaluation design is fundamentally concerned with the overall strategy for conducting an evaluation. This encompasses the framework and methodology that guide how the evaluation will be executed, including defining the evaluation questions, selecting appropriate methods for data collection and analysis, and determining the criteria for success. A well-structured evaluation design ensures that the evaluation is systematic, focused, and capable of effectively addressing the objectives and questions posed. This strategic approach ultimately leads to more valid and reliable results that can inform decision-making about a program or intervention's effectiveness.

In contrast, the details of the program's budget, timeline for data collection, and selection of participants for focus groups, while all important aspects of evaluation planning, are components or logistical elements that fall under the broader umbrella of the evaluation design itself. They do not encapsulate the comprehensive strategy needed to conduct the evaluation successfully.
