Coherence

Coherence is one of five evaluation criteria used by the Organisation of Economic Development Cooperation (OECD). The other four are relevance, efficiency, sustainability, impact, and effectiveness. The OECD Development Assistance Committee Network on Development Evaluation defines coherence as “the compatibility of the intervention with other interventions in a country, sector or institution.”. In simpler terms, the main question under coherence is “how well does the intervention fit?”.
