Outcome Harvesting



Understanding social change results in complex circumstances


What is it?

Outcome Harvesting is a monitoring, evaluation and learning approach that serves the needs of managers, donors and evaluators attempting to solve intractable problems, unexpected challenges in development and social change.

Inspired by Outcome Mapping and informed by Utilization-Focused Evaluation, Outcome Harvesting enables monitoring and evaluation professionals, grant makers, managers and implementers to identify, formulate, verify, and make sense of outcomes.

Outcome Harvesting has proven especially useful in hundreds of civil society and governmental projects, programmes and organizations in over 140 countries on all seven continents.

Outcome Harvesting is implemented in six key steps and can be customized to the specific needs of your organization

When should I use it?

When the main focus is on outcomes

Outcome Harvesting emphasis is in effectiveness instead of efficiency or performance, allowing to learn what was achieved and how.

If the programming context is complex

Outcome Harvesting is suitable for unpredictable and complex environments where relations of cause and effect are not fully understood.

When the purpose is monitoring and evaluation

Outcome Harvesting is designed not only to track changes in behaviour of social actors influenced by an intervention but also to support learning about achievements.

Outcome Harvesting: Evaluation for Social Change

Outcome Harvesting (OH) is often used by international practitioners based in the USA, yet it is rare to see OH applied to domestic programs. The webinar aims to help spread the word by sharing examples of how OH can be used to evaluate social justice initiatives within the US context. 

The meeting time is 16:00 UTC, to be accessible to colleagues in the Americas, Europe and parts of Africa and the Middle East. There is a US$ 20 charge for non-members of the Seattle and Boston evaluation networks, to help those networks remain sustainable.
