All this explains why the evaluation method known as Outcomes Harvesting has been gaining so much traction in these last years. Based on the principles of Outcomes Mapping, which it fully integrates and adapts to the purposes of evaluation, outcomes Harvesting is an “utilisation- focused, participatory tool that enables evaluators, grant makers, and programme managers to identify, formulate, verify, and make sense of outcomes they have influenced when relationships of cause-effect are not always known. Unlike most other evaluation methods, Outcome Harvesting does not measure progress towards predetermined outcomes or objectives, but rather collects evidence of what has been achieved, and works backward to determine whether and how the project or intervention contributed to the change.”
