Adapting evaluation in the time of COVID-19 — Part 2: DEFINE

The Covid-19 pandemic has led to rapid changes in the activities and goals of many organisations, whether these relate to addressing direct health impacts, the consequential economic and social impacts or to the need to change the way things are done. Evaluation needs to support organisations to use evidence to plan these changes, to implement them effectively, and to understand whether or how they work – in short to articulate an appropriate theory of change and use it well.
