Planning an Evaluation
In planning an evaluation it is important to identify key questions the organization may have. From these, we can determine how many of those questions can be answered from prior impact evaluations or from an improved systems of process evaluation. Assuming we haven’t found all our answers, we must then pick a few top priority questions that will be the primary focus of our impact evaluation. Finally we should draw up plans to answer as many questions as we can, keeping in mind that fewer high quality impact studies are more valuable than many poor quality ones.
The first step in an evaluation is to revisit the program’s goals and how we expect those goals to be achieved. A logical framework or theory of change model can help in this process. (See Program Theory Assessment) As part of assessing the purpose and strategy of a program, we must think about key outcomes, the expected pathways to achieve those outcomes, and reasonable milestones that indicate we’re traveling down the right path. As expected in an evaluation, these outcomes and milestones will need to be measured, and therefore transformed into “indicators” and ultimately “data”. (See Goals, Outcomes, and Measurement.)
Only after we have a good sense of the pathways, the scope of influence, and a plan for how we will measure progress, can we think about the actual design of the evaluation.
