Outcome Harvesting

Summary

Outcome Harvesting starts from observed changes — outcomes — rather than planned activities, and works backwards to determine whether and how the campaign contributed to them. It is designed for contexts where causal chains are too complex or contested for conventional before/after measurement.

Body

Outcome Harvesting is a qualitative evaluation method that inverts the normal evaluation logic. Instead of asking did our activities produce the planned outputs? it asks what changed, and did we contribute? This makes it particularly suited to campaigning, where outcomes (a policy shift, a target’s changed position, a new institutional practice) emerge from complex causal chains involving many actors the campaign cannot fully control.

BetterEvaluation’s Rainbow Framework organises qualitative evaluation approaches into seven tasks and documents complementary methods such as Most Significant Change, which (like Outcome Harvesting) is built for surfacing unanticipated change through stakeholder accounts rather than pre-defined indicators [source: betterevaluation]. The method is particularly relevant when: conventional indicators cannot capture the change; the campaign works through influence rather than direct action; or the causal chain involves actors outside the campaign’s direct observation.

The six-step process:

  1. Identify the outcomes — what changed (observed changes, not planned ones)
  2. Verify that the campaign contributed — without the campaign’s intervention, would this change have happened?
  3. Assess the contribution — what did the campaign specifically contribute?
  4. Identify the contribution story — the causal chain linking campaign activity to outcome
  5. Draw lessons — what does this mean for the campaign’s theory of change?
  6. Report and use findings

The contribution question is the discipline: The honest answer to did we cause this? is usually we contributed alongside others. Outcome Harvesting forces the campaign to name the other actors and factors honestly, which is the same discipline as contribution analysis and the theory of change assumptions column.

Common pitfalls: Harvesting outcomes without verifying contribution turns the method into a vanity exercise. The did we contribute? question must be answered honestly.

Use it for

Evaluating advocacy campaigns with complex causal chains; documenting unexpected outcomes; building contribution narratives for funders; complementing quantitative indicator tracking with qualitative depth.

Worked examples

  • moroccan-feminist-groups-campaign-to-reform-moudawana — a hypothetical post-reform Outcome Harvesting exercise would surface the women’s coalition’s contribution to the 2004 Mudawana reform alongside other factors (the King’s intervention, the Islamist counter-mobilisation, the international human-rights context); the OH discipline is the framing, not a claim that the example was actually conducted this way.
  • south-african-blacks-boycott-apartheid-in-port-elizabeth-1985-86 — a retrospective OH-style reflection on the anti-apartheid movement’s contribution alongside other factors (the 1990–94 transition) would be one example where the OH discipline can be applied; the practitioner literature on retrospective OH for transformative political transitions is the next reading target.

FAQ

What is Outcome Harvesting?

Outcome Harvesting is a qualitative evaluation method that inverts the normal evaluation logic: instead of asking did our activities produce the planned outputs? it asks what changed, and did we contribute? [source: betterevaluation]. It starts from observed changes — outcomes — rather than planned activities and works backwards to determine whether and how the campaign contributed to them, which makes it particularly suited to campaigning where outcomes emerge from complex causal chains involving many actors the campaign cannot fully control.

When is Outcome Harvesting the right method?

Outcome Harvesting is particularly relevant when conventional indicators cannot capture the change, the campaign works through influence rather than direct action, or the causal chain involves actors outside the campaign’s direct observation [source: betterevaluation]. BetterEvaluation’s Rainbow Framework organises qualitative evaluation approaches into seven tasks and documents complementary methods such as Most Significant Change, which is built for surfacing unanticipated change through stakeholder accounts rather than pre-defined indicators.

What is the six-step Outcome Harvesting process?

The six-step process is: (1) identify the outcomes — what changed (observed changes, not planned ones); (2) verify that the campaign contributed — without the campaign’s intervention, would this change have happened; (3) assess the contribution — what did the campaign specifically contribute; (4) identify the contribution story — the causal chain linking campaign activity to outcome; (5) draw lessons — what does this mean for the campaign’s theory of change; and (6) report and use findings [source: betterevaluation].

Why is the contribution question the discipline?

The honest answer to did we cause this? is usually we contributed alongside others — Outcome Harvesting forces the campaign to name the other actors and factors honestly, which is the same discipline as contribution analysis and the theory of change assumptions column [source: betterevaluation]. The common pitfall is harvesting outcomes without verifying contribution, which turns the method into a vanity exercise; the did we contribute? question must be answered honestly.

Open Questions

Does a campaigning-specific Outcome Harvesting guide or case study exist? The local BetterEvaluation scrape names Most Significant Change alongside the Rainbow Framework’s task structure, but does not describe Outcome Harvesting’s six-step methodology. A targeted scrape of BetterEvaluation’s OH page, or a fetch of the original Wilson-Grau manual, is the next sourcing target.
