Theory of change

Home » About NPC » Our expertise » Theory of change

What is theory of change? We all have dreams and ideas about how to achieve them, but we rarely take the time to think these through, scrutinise and articulate them. This is what a theory of change process does.

We see theory of change as the foundation of charity strategy, evaluation and communication. Our free guidance is one of the most popular resources we offer. To get started on your theory of change, read our Theory of change in ten steps.

To dig deeper, we run regular training sessions, and our consultants can help you develop bespoke theories of change for your projects and services.

Organisations we've worked with

RNID

We helped the RNID to develop theories of change for four new programme areas, as well as a clear and consistent approach to impact measurement to use across the organisation. RNID moved from planning to real world delivery of well-evidenced, targeted, life-changing activity across its programmes.
