How do we use a Theory of Change to make change happen?

The weak and broken links point to places where interventions are needed. By identifying and focusing attention on places where the theory breaks down in practice, you can make better use of limited time and resources. Interventions crafted in this way are measurable and can be prioritized according to impact and cost – from “high impact/low cost” on one end to “low impact/high cost” on the other.
