Contribution analysis
An approach to exploring cause and effect
A 4-page brief that explains contribution analysis, a way to make a credible claim that a programme contributed to an observed change when an experiment or control group is not practical. It sets out how to test the programme's theory of change against evidence and consider other factors that may explain the outcome. Evaluators, programme staff and funders use it to plan and report on contribution claims.

Outcome Harvesting
A brief that introduces outcome harvesting, a participatory method for identifying, verifying and making sense of outcomes when cause and effect are unclear. The evaluator collects evidence of what changed and works back to assess whether and how the intervention contributed. It explains the core concepts and steps. Evaluators and teams use it for advocacy, policy and other complex work where results cannot be set in advance.
