A Theory of Change (ToC) is a strategic framework that outlines how and why a particular intervention is expected to achieve its intended impact. It maps out the step-by-step process from activities to outcomes, helping organizations, policymakers, and evaluators understand the logic behind a program or initiative.
What are the key components of a Theory of Change? #
The key components of a Theory of Change include:
- Inputs and Activities – The resources and actions required to implement the program.
- Outputs – The immediate results of program activities, such as services delivered or products created.
- Outcomes – The short-term and medium-term changes resulting from the intervention.
- Impact – The long-term, sustainable change that the program aims to achieve.
- Assumptions -The underlying beliefs about how change will occur and the external factors that may influence success.
Why is Theory of Change important? #
Clarification of Program Logic: It helps stakeholders understand how activities contribute to desired outcomes.
Enhancement of Planning and Adaptation: It provides a roadmap for implementation and allows for adjustments based on evidence.
Evaluation Support: ToC establishes measurable indicators for assessing progress and effectiveness.
Improvement of Stakeholder Engagement: It ensures alignment among funders, implementers, and beneficiaries.
What are the Limitations of the Theory of Change? #
Developing a ToC requires time, stakeholder input, and a deep understanding of the context. If not well-defined, it may oversimplify complex change processes.

Introduction to Theory of Change
This video tutorial by Research to Action gives an overview of the theory of change, why it is useful, the difference between an organization’s ToC and a project’s ToC, the various components of a ToC, and other important details.
This guide by the Australian Institute of Family Studies gives a brief overview of the theory of change and program logic models, as well as provides the key elements of the theory of change, along with examples and further resources.

This report, published by the Annie E. Casey Foundation, helps funders and program implementers achieve their social change goals. It covers theory of change models, processes, and outcomes, along with key concepts, benefits, and limitations.
This companion guidance by the UNDAF provides an in-depth understanding of the concept of a theory of change, its focus and methodology, its key principles, and the steps for developing a theory of change. It also explains how to move from theory to practice in applying a theory of change.

Independent Evaluation Group (IEG) FY26 Work Program and Budget and FY 27-28 Indicative Plan
This Budget and Indicative Plan elaborates on IEG’s plan to develop Theories of Change (ToC), which will be a core component of IEG’s evaluation selection process going forward. Theories of Change (ToCs) and evidence gap maps help identify key evaluation questions and prioritize evidence gaps for IEG’s work across thematic streams and sub-streams.
This report, written by Louise Twining-Ward, Hannag Messerli, Amit Sharma and Jose Miguel Villascusa Cerezo, explains Finance, Competitiveness and Innovation (FCI) Global Practice’s Tourism Theory of Change. ToC projects and programs that connect to project goals and development objectives and help maximize tourism’s potential. The report articulates the ‘why’ and ‘how’ of FCI’s approach to project design and implementation.
