This poster was presented by Julius Nyangaga and Esther Kihoro at the OMLC Learning Lab 2025.
This poster explores a critical challenge facing Outcome Harvesting (OH): how to maintain methodological integrity while meeting evaluation requirements that extend beyond behavioural change assessments. When evaluations must address the OECD-DAC criteria, necessary quantitative evidence, institutional changes, and varied stakeholder interests, OH alone may be insufficient.
Drawing from two Kenyan projects—the Gender Inclusive Vaccine Ecosystem (GIVE) agricultural development initiative and Undugu Society's urban youth rights program—this poster demonstrates how OH can function as a strategic component within broader evaluation approaches. The bricolage approach presented here shows how to integrate complementary methods (surveys, DAC frameworks, institutional analysis) while preserving OH's core strengths: its focus on behavioural change, contribution analysis, and outcome significance assessment.
Key insights include practical strategies for analysing stakeholder needs, mapping methods to evaluation questions, integrating data collection instruments, and triangulating findings across multiple sources. The case studies reveal how this integrated approach enabled comprehensive evaluations that quantified outcomes, validated theories of change, assessed gender impacts, and provided strategic insights for future programming – all while honouring OH principles.
