The theory of change is the step by step by which we hope to achieve changes in the lives of others. It is a fundamental tool to design, implement and evaluate projects with social impact. It helps understand how an intervention transforms people's lives and contexts, detailing what the intervention is specifically and what changes it is expected to generate.

What are the components of a theory of change?

The theory of change is built from interconnected components that allow tracing the path from the actions of a program to the significant changes that are to be achieved. Each component fulfills a specific function in this narrative of change. Below, we break down the key elements that make up a theory of change, following the Resuelve approach.

1. Interventions: what the intervention does Interventions are the concrete actions that an intervention takes to address a specific problem or need. These activities are the starting point of any theory of change. They include everything from training, therapies and awareness campaigns to distribution of resources or implementation of policies. It is important that interventions are clear and aligned with the objective of the intervention. For example, in a program to improve adolescent mental health, interventions could be social-emotional skills workshops and group therapy sessions.

2. Outputs: what your participants receive Outputs are the immediate and tangible results that participants obtain by engaging in the interventions. They represent the direct response to the actions taken. In other words, they are the “product” of the work of the program or project. In the case of the mental health program, the exits could be adolescents who attend the workshops and actively participate in the therapy sessions. This is the first indication that the interventions are reaching their target audience.

3. Results: what is achieved by receiving it The results reflect the short and medium term changes that occur as a consequence of the departures. This is where it is observed whether the intervention activities are generating transformations in the knowledge, skills, attitudes or behaviors of the participants. Returning to the example, outcomes could include adolescents learning to manage their emotions or developing skills to cope with stressful situations. These changes are fundamental because they build the path to the desired impact.

4. Impacts: what changes by achieving it Impacts represent the deepest and most sustainable change that an intervention seeks to generate in people's lives or in a specific social context. This is the ultimate goal of any theory of change and usually manifests itself in the long term. In the mental health program, the impact could be that adolescents are able to live fuller lives, with greater emotional well-being and the ability to actively participate in their communities. The impacts are the reason for the program and justify the investment of resources and effort.

5. Assumptions: what has to be true for this path to occur Finally, although less common, assumptions are the external conditions or beliefs that must be met for each step in the theory of change to work as expected. These factors may include aspects such as the interest of participants, the commitment of allies, the political or social context, and other elements outside the direct control of the intervention. For example, an assumption in the case of the mental health program could be that adolescents regularly attend sessions and that facilitators have the necessary skills to guide the process.

Why does a theory of change matter?

Having a clear theory of change allows you to communicate, demonstrate and convince others that a social intervention will generate changes in the lives of others.

Provides clarity to the project team and allies by detailing how and why the intervention generates change. Avoiding falling into improvisation and aligning efforts towards a common objective.

In addition, the theory of change acts as a compass that guides the actions of any program and allows it to evaluate its effectiveness. When things don't go as planned, you can go back to this model and analyze which part of the path is not working as it should. Perhaps the outputs are not reaching the right participants, or the results are not being as significant as expected. By having this tool, strategies can be adjusted and interventions strengthened to ensure real impact.

It is also a powerful tool for accountability. Well, financiers, allies and donors not only want to know that the resources provided are being used; but above all they want to see the tangible results and real changes that are generated with it. A well-structured theory of change demonstrates that the project has a solid plan to generate transformations and on which it is easier follow up.

How to communicate a theory of change?

The key is to structure a narrative that is logical and persuasive, using practical examples and accessible language. Communicating a theory of change can be a challenge, since it involves transferring complex ideas into clear messages that are accessible to diverse audiences: from strategic allies and funders to work teams and beneficiary communities. Below we will explore how to do this, with examples that illustrate its application.

  1. **Propose a clear thesis **Establishes the relationship between the actions that the program will carry out (the interventions) and the expected changes. A simple and effective way to clarify your theory of change is to use an “IF… AND… THEN…” formula. For example:

    • YES we strengthen the capabilities of older adults in the use of smartphones,
    • And we raise awareness among application developers about improving the experience for older adults,
    • THEN the daily use of technology in older adults will increase,
    • And they will have greater possibilities of reaching an agreement with their loved ones,
    • AND not to experience loneliness or feel depressed.

  2. Simplify the terms and avoid technical language Make sure the concepts and terms used are easy to understand for your target audience. Instead of talking in technical language with concepts like 'quantitative impact indicators', you can say "the evidence to know if we are achieving the desired change." For example:

    • “If we train rural teachers to use digital tools in their classes, and provide them with access to appropriate technology, then students in these schools will be able to learn more and improve their skills for the future.”

  3. Incorporate a visual guide with diagrams A graphic or infographic can be a powerful tool to complement the message. Diagrams showing how interventions, outputs, outcomes, impacts and assumptions are connected make the theory of change more understandable. For example

    • The diagram can show how activities (teacher training and book distribution) lead to immediate outputs (improved classes and students with learning materials), and how this results in medium and long-term changes (increased literacy rates and reduced poverty).

  4. Rely on real examples Beyond data, personal stories and real examples are powerful in communicating a theory of change. You can use a narrative that illustrates the expected impact. For example:

    • "Isabela is an 18-year-old girl who grew up in a rural community without access to higher education. Through our program, she received vocational guidance, a scholarship, and access to entrepreneurship workshops. Today, María is not only the first in her family to finish her studies, but she is also starting a business that employs other young people in her community. If we expand this program, hundreds of young people like María will be able to transform their lives and their communities."

Examples of theories of change

Any theory of change is divided into segments: activities, outputs, results and impacts. The way to summarize it in a single sentence is also known as an impact thesis and makes it easier to understand how each component connects and contributes to the desired change.

  1. From an education project: Impact Thesis: If we train teachers in teaching techniques and provide them with educational materials, and these teachers apply what they learn in their classrooms, then students will have better learning opportunities, which will contribute to reducing the educational gap in rural communities.

    • Interventions: Training for teachers in innovative teaching techniques and delivery of educational materials.
    • Outputs: Teachers trained in active methodologies and schools with access to learning resources.
    • Results: Teachers who apply new strategies in the classroom, more engaged students and better learning levels.
    • Impacts: Reduction of the educational gap in rural communities and greater equality of opportunities.

  2. From a financial empowerment program: Impact thesis: If we provide business training to women in vulnerable communities, and provide them with access to microcredit, then they will be able to start sustainable businesses, generating income for their families and reducing poverty.

    • Interventions: Business skills workshops and access to microcredits.
    • Outputs: Women trained in business management and with access to capital to start or expand their ventures.
    • Results: Women who start sustainable businesses and generate stable income.
    • Impacts: Reduction of poverty in their homes and communities, and greater economic autonomy for women.

  3. From an education project: Impact Thesis: If we train teachers in teaching techniques and provide them with educational materials, and these teachers apply what they learn in their classrooms, then students will have better learning opportunities, which will contribute to reducing the educational gap in rural communities.

    • Interventions: Technical training programs and soft skills workshops.
    • Outputs: Teachers trained in active methodologies and schools with access to learning resources.
    • Results: Teachers who apply new strategies in the classroom, more engaged students and better learning levels.
    • Impacts: Reduction of the educational gap in rural communities and greater equality of opportunities.

  4. Of a tangible product: Impact Thesis: If we train teachers in teaching techniques and provide them with educational materials, and these teachers apply what they learn in their classrooms, then students will have better learning opportunities, which will contribute to reducing the educational gap in rural communities.

    • Interventions: Manufacturing affordable water filters and training to teach families how to properly install and use filters.
    • Departures: Families with access to drinking water sources in their homes.
    • Results: Decrease in time spent obtaining drinking water.
    • Impacts: Reduction in the presence of water-borne diseases, such as diarrhea and cholera.
