Why We Do Not Measure Impact At Scale (And Are Unapologetic About It)
At Evidence Action, we do not typically measure final impacts when we implement a program at scale. By “impacts” we mean the metric of ultimate interest - the real reason we are doing what we are doing. We don’t measure whether households with Dispensers have less diarrhea or child mortality. We don’t measure whether children that get dewormed attend school more or have better cognitive scores. We measure whether people use chlorine and whether worm infection levels fall.
Measuring “means” rather than “ends” could be a controversial stance in an NGO community where M&E teams pride themselves in always measuring ‘impact.’
We think we are doing the right thing. Here’s why.
