Understanding the Theory of Change
A Theory of Change maps how services create impact, showing the steps from need to outcome and making the pathway to change clear for organisations, staff, and communities.
When someone steps into a community organisation, they are usually carrying something with them. It might be a problem to solve, a hope to chase, or a need they cannot quite name yet. Big or small, urgent or long-standing, what brings them through the door is a belief that things can, and need, to be different, and a promise that this difference can be achieved.
The staff and volunteers in these organisations already understand that promise. They see it play out every day as they guide and support people on their journey of change. For a long time, that gut-level understanding was enough. More and more, though, there is a push to put that promise into words and shape it into a clear framework: a Theory of Change.
What is a Theory of Change?
A Theory of Change (ToC) is essentially a map. It is usually drawn as a diagram or flow chart that spells out the impact a service, initiative or programme is aiming for. Rather than stopping at the end goal, a ToC digs into the “how.” It lays out the steps in order, showing the cause-and-effect relationships that carry people along the journey.
The beauty of a ToC is that there is no single template. They are flexible and can be shaped to fit different purposes. Sometimes a ToC zooms right out, describing whole-of-organisation processes, connecting them to wider social and economic factors, and exploring how change ripples through families and communities. Other times it zooms in, focusing tightly on the pathway of participants through a specific programme or intervention.
Whatever the scope, every ToC shares three core elements:
- Identifying need: A ToC starts with the question of need. What challenge is being addressed? Who is being served? What barriers stand in the way and what enablers can be unlocked?
- Mapping the journey: The ToC then charts the steps a service takes to guide participants forward, showing the logic and cause-and-effect links that drive progress. It turns the tacit into something visible and concrete.
- Locating the destination: Finally, a ToC sets out the destination. What outcomes will be achieved? What will success look like when someone leaves the service? What is the ideal end state being worked towards?
At its heart, a Theory of Change is both practical and powerful. It captures the story of how change happens, making it easier to explain, test, and share with others.
Why create a Theory of Change?
A Theory of Change is more than a diagram on a page. It captures the focus and essence of a service and puts it into words and pictures that everyone can understand. The value it brings depends on when and why it is created. Early on, it can be a roadmap that sets out ambitions and expected impacts during programme design. Once a service is running, it can turn the unspoken know-how of staff into an explicit strategy. And for mature, well-established services, it can be a clear way to show others how impact is being created and why it matters.
Whatever stage a service is at, a ToC brings three major benefits:
- Creating a shared vision: A ToC gives everyone a common north star. It pulls together purpose, intent and success criteria into a single source of truth that people can rally around.
- Identifying causal relationships: A ToC highlights how the service being delivered leads to change. It encourages organisations to think carefully about the links between inputs, activities and outcomes, to surface assumptions, and to spot barriers and enablers along the way. In doing so, it makes the “logic of change” visible.
- Supporting ongoing monitoring and evaluation: Once a ToC is in place, it can be used as a living framework for improvement. Assumptions can be tested against evidence and data, and the model can be refined over time, shifting from a sketch of possibilities to a well-defined guide with clear conditions for success.
Tying these benefits together is the most powerful one of all: communication. A ToC takes the complexity of a service and distils it into a story that anyone can follow. Whether the audience is frontline staff, funders, evaluators, or someone encountering the service for the first time, a ToC builds clarity and confidence that the original promise of change is being delivered.
A Theory of Change gives the big-picture map: where you are headed, how you plan to get there, and what success will look like when you arrive. But sometimes you need to zoom in closer to capture the fine-grain detail of a single programme to show the direct, uninterrupted pathway to impact. That is where Intervention Logic comes in, the close cousin of the Theory of Change and the focus of our next post.

Why measuring social impact matters to funders and housing providers
Measuring social impact in housing helps funders and providers target services to residents’ real needs, improve wellbeing, reduce costs, and guide smarter decisions across the housing lifecycle with stronger outcomes for people and communities.
Reaching the 15% with the Highest Needs
Reaching the 15% with the Highest Needs – 15% of Kiwis account for half of all social service use, yet mainstream support often falls short. By redesigning services around real needs, we can drive better outcomes for those most at risk.
Trust is the social sector’s most valuable currency
Trust is a vital social currency in the sector. By combining engagement data with lived experiences, organisations can gain deeper insight into relationships and better understand, measure, and strengthen trust with the communities they serve.
