Keeping a results-based evaluation and ROI process on track is one of biggest implementation challenges for evaluation professionals. In many ways, it's equivalent to training for a marathon. You start small with manageable goals, stretch your muscles, change your habits, celebrate milestone events, and then wait for the training and preparation to kick in so you can go the distance. Yet the similarity ends there, since for us "going the distance" represents just half of the journey. Staying on track and maintaining the health and integrity of the ROI process in the face of continuous change is equally critical and an aspect of results-based evaluation work that is often overlooked and underestimated.
