Base evaluation decisions on a clear program logic. The Armenia roads rehabilitation was designed to improve the economic performance of the agricultural sector; however, the initial program logic was fairly vague about the pathways through which this would occur. In addition, there was limited evidence available on which to base the original program logic. This made the evaluation design more challenging as the specific outcomes to be assessed were defined in general terms, and there were no clear theories about the expected timing of changes in those outcomes. The decision of when and what data should be collected should be driven by a clear program logic that underlies the investment decision.
