Iona Joy, Head of charity team at NPC, presented on NPC's approach to measurement at the CSV conference in March 2015. NPC works at the nexus between charities and funders to increase the impact of both. NPC uses a four pillar approach to measuring impact that involves mapping a theory of change, prioritizing outcomes to measure, choosing an appropriate level of evidence, and selecting data sources and tools. An effective measurement framework is developed through this process to help charities strategically plan, deliver, assess, and review their impact.
