Purpose
Theory of Change translates a desired impact into a traceable chain of change. It makes assumptions, intermediate goals, and measurement points visible before a program is rolled out at scale.

Theory of Change
Explains which changes contribute to the intended impact and how that contribution is assessed.
A Theory of Change explains how an initiative is expected to contribute to long-term impact through necessary intermediate changes. It makes causal assumptions, context and measurement visible.
Which changes must occur for our initiative to contribute to the intended impact?
- Participants
- 4-12 participants
- Time
- 90–150 minutes for a draft; evidence review and monitoring in later sessions.
Impact goal
Impact goal
Define population, measurable long-term change and horizon.
Work backwards
Work backwards
Work backwards from the goal to necessary early and intermediate changes.
Assumptions
Assumptions
Record mechanisms, contextual assumptions and evidence for each link.
Interventions
Interventions
Link interventions to the changes they should produce.
Measurement
Measurement
Set indicators with baseline, target, timing and data source.
When evidence changes, revise the affected causal link, assumption and intervention together.
A good fit when
For programmes with several outcome levels and stakeholders, especially before choosing interventions or evaluation.
Ideal for
- Impact Programs
- Strategy Design
- Change Initiatives
Not good for
- Short-term task planning
- Feature scoring without causal logic
Outputs
Outcome pathway and measurement plan
Outcome pathway with preconditions, assumptions, interventions and testable indicators.
Measurement and learning plan
The measurement and learning plan contains a short causal narrative and distinguishes the initiative’s contribution from alternative explanations in evaluation.

Fictional example
A Theory of Change explains how an initiative is expected to contribute to long-term impact through necessary intermediate changes. It makes causal assumptions, context and measurement visible.
Long-term impact
For whom should what change by when? Which contribution is within our influence?
Fictional: A neighbourhood programme aims to enable more independent online public-service transactions after twelve months. Target: 60% complete a defined task unaided; baseline still needs measurement.
Outcome pathway
Which early and intermediate changes are necessary? Record links with conditions and rationale.
Guided practice → confident performance in a practice case → independent everyday application → more unaided transactions. Device access AND understandable real forms are additional preconditions.
Assumptions and evidence
Which mechanisms, contextual factors and alternative explanations apply? What is evidenced or open?
Open: practice transfers to real forms. Risk: forms change. Check through later voluntary real tasks; separately record external portal improvements.
Interventions and outputs
Which activity delivers which immediate output and is expected to change which outcome?
Mira organises four guided practice sessions and device lending. Four sessions are outputs; independent task completion is the outcome.
Indicators and learning
Set indicator, baseline, target, data source, timing, owner and adaptation decision.
Mira measures the share of defined tasks completed unaided before starting and after three and twelve months. Baseline open, twelve-month target 60%. If transfer fails, the team examines task realism and access before adding sessions.
All example details are fictional and illustrate the application.
First step
Agree the population, desired change and time horizon.
Deep dive
How it works
The team starts from the long-term impact and works backward to outcomes, outputs, and activities. Assumptions are named explicitly, and measures are chosen so they test the program's logic. The result is a robust impact model for planning and evaluation.
In detail
Theory of Change works because it formulates the path from intervention to impact as a reasoned chain of changes. Good application lays assumptions open, describes intermediate steps cleanly, and does not confuse desired impact with activity. This reveals where the logical path is thin, which prerequisites are tacitly assumed, and where evidence delivers the greatest benefit.
Facilitation
Start from the desired end state and work backward through necessary changes without skipping steps. The sensitive point is where a chain only holds together if a strong unverified assumption is tacitly accepted. Close with a readable chain of impact, the riskiest assumptions, and the signals that let the team observe whether they hold.
The method guide walks execution through 5 phases, timing, 5 pitfalls, and clear stop criteria.
