What exactly is Theory of Change? In this video, I break down one of the most powerful tools in project and change management. Theory of Change helps you map how your activities lead to outcomes and long-term impact. It’s widely used in government, NGOs, charities, business transformation, and strategic planning.
This video is safe for viewing in the workplace.
This is learning, so, sit back and enjoy
Theory of Change
Theory of Change (ToC) is a clear description of how and why you expect change to happen. It sets out the links between what you do and the results you want. It often includes a diagram and a short narrative.
It is a description of how and why a certain change is expected to happen. Think of it as filling in a missing piece of the puzzle.
- On one side, you have your Activities (the things you do).
- On the other side, you have your Long-Term Goal (the big change you want to see).
The Theory of Change “fills in” the steps and conditions needed to connect your daily activities to that long-term goal.
Why is Theory of Change Useful to Project and Change Managers?
Theory of Change is highly valuable for project and change managers because:
- Planning: It clarifies what you want to achieve and how to get there.
- Communication: It allows you to let others know what your project or programme is trying to achieve and how you are going about it.
- Alignment: It brings all stakeholders together, creating agreement on aims and success measures.
- It exposes assumptions and complexities in your plan.
- It helps you plan monitoring and evaluation methods from the start.
- It supports better decision-making by making links between actions and outcomes clear.
For example, a government department might use Theory of Change to get agreement on a strategy to improve refugee integration, mapping everyone’s roles and the outcomes needed to achieve success.
How Does Theory of Change Work? (Outline Process)
I am going to split the tasks into 4 phases of work:
Phase 1: Goal Focus
- Define the long-term goal (The Ultimate Impact)
- Identify stakeholders and agree the long-term impact
- Collect evidence and establish the context
- Work backwards to identify outcomes
- Define outputs and activities
Phase 2: Input Focus
- Identify inputs (resources)
- Make assumptions explicit
- Identify risks
Phase 3: Process Focus
- Map the causal links
- Identify activities and interventions
- Draw causal links
- Add timelines
- Produce the diagram and narrative
Phase 4: Review Focus
- Review and improve
- Build a monitoring and evaluation plan
Short Example of a Theory of Change
Suppose a charity wants to reduce youth unemployment.
- Impact: Fewer young people unemployed locally.
- Outcomes: More young people with job skills. More youth applying for jobs.
- Outputs: Training sessions delivered. CV workshops run.
- Activities: Organise courses. Partner with local employers.
- Inputs: Funding, trainers, venues.
- Assumptions: Young people want to work. Local employers have vacancies.
- Risks: Low attendance. Economic downturn.
- Indicators: Job applications, Job starts, Unemployment statistics
- Causal links: Training sessions lead to skills, skills lead to jobs.

Conclusion about Theory of Change
Theory of Change is a step-by-step approach that makes complex projects clearer, more achievable, and measurable. It helps project managers and change leaders plan in a smarter, more inclusive way and gives a solid foundation for delivery, tracking progress, and reporting results.
By working backwards from your desired impact, you create a roadmap that shows:
- Where you’re going
- How you’ll get there
- What needs to be true for success
- How you’ll know if you’re on track
The investment in developing a Theory of Change pays dividends throughout your project’s life. It turns vague aspirations into concrete plans and helps everyone work towards the same goals.

What Kit does a Project Manager Need?
I asked Project Managers in a couple of forums what material things you need to have, to do your job as a Project Manager. They responded magnificently. I compiled their answers into a Kit list. I added my own.
