Set realistic time horizons. Inevitably there are delays in large infrastructure projects. From the beginning, implementers and evaluators should build into the evaluation design actions for mitigating risk to the evaluation associated with delays in implementation. In the case of Honduras, given the delays in implementation and inflexibility in the evaluation schedule, the exposure period to the improved roads network in some cases was only 5-6 months, whereas for some sections of CA-5 highway rehabilitation wasn’t completed at the time of endline data collection. This is a limited exposure period when decision makers are interested in looking at longer term outcomes, such as changes in prices and income.
