Prerequisite

What needs to be finished first

Complete firstImpact goal

Name the population and social change.

Without an agreed destination, activities become arbitrary.
Complete firstPerspectives

Involve affected people, delivery and evaluation.

Mark missing perspectives as an evidence gap.
02

Preparation

What needs to be ready before start

Materials

Outcome board, contextual evidence, indicator table.

People / roles

Affected people, programme team, evaluator, facilitator.

Pre-read

Agree the population, desired change and time horizon.

Time needed

90–150 minutes for a draft; evidence review and monitoring in later sessions.

Setup

Place impact at the right and map preconditions backwards. Keep link assumptions, interventions and indicators distinct alongside it.

03

Core question

The one question this method answers

Which changes must occur for our initiative to contribute to the intended impact?

04

Flow

Phases with goal, actions, output and pitfall

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.

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.

    Impact goal

    Impact goal

    Goal

    Impact goal

    Inputs for this step

    • Mandate and context

    Actions

    • Define population, measurable long-term change and horizon.
    • Explicitly bound the initiative’s influence and external factors.

    Output

    Impact goal

    Does the goal describe a change for people?

    Quality check

    Does the goal describe a change for people?

    Pitfall

    Workshop count is treated as impact. Separate delivered outputs from resulting changes.

    Timing: 15–20 minutes

  2. 2

    Work backwards

    Work backwards

    Goal

    Outcome pathway

    Inputs for this step

    • Impact goal and experience

    Actions

    • Work backwards from the goal to necessary early and intermediate changes.
    • Explain why each predecessor is needed; examine additional conditions and alternative pathways.

    Output

    Outcome pathway

    Is a necessary precondition missing?

    Quality check

    Is a necessary precondition missing?

    Pitfall

    A linear success chain is forced. Show parallel conditions and feedback.

    Timing: 25–35 minutes

  3. 3

    Assumptions

    Assumptions

    Goal

    Assumption register

    Inputs for this step

    • Pathway and studies

    Actions

    • Record mechanisms, contextual assumptions and evidence for each link.
    • Capture conflicting experience and conditions beyond your control; prioritise critical gaps.

    Output

    Assumption register

    Are assumptions testable and distinct from facts?

    Quality check

    Are assumptions testable and distinct from facts?

    Pitfall

    Agreement replaces evidence. Investigate the weakest link with evidence or a test.

    Timing: 20–30 minutes

  4. 4

    Interventions

    Interventions

    Goal

    Intervention plan

    Inputs for this step

    • Reviewed causal assumptions

    Actions

    • Link interventions to the changes they should produce.
    • Check resources, ownership and scope; track output counts separately.

    Output

    Intervention plan

    Does each intervention have a justified mechanism?

    Quality check

    Does each intervention have a justified mechanism?

    Pitfall

    Existing activities dictate the goal. Reconsider the intervention from the required outcome.

    Timing: 15–25 minutes

  5. 5

    Measurement

    Measurement

    Goal

    Measurement and learning plan

    Inputs for this step

    • Pathway and data access

    Actions

    • Set indicators with baseline, target, timing and data source.
    • Write a short causal narrative; distinguish the initiative’s contribution from alternative explanations in evaluation.

    Output

    Measurement and learning plan

    Could a negative finding change the theory?

    Quality check

    Could a negative finding change the theory?

    Pitfall

    Improvement over time is treated as causal proof. Examine other influences and interpret contribution cautiously.

    Timing: 15–30 minutes
