Whether you're managing a health intervention, designing an education programme, or overseeing a development project, you need a clear framework that connects your efforts to your intended results. This is where logic models become essential.
A logic model is more than a visual planning tool. It is a strategic blueprint that aligns your programme’s goals, activities, and outcomes in a way that makes evaluation possible and purposeful. If you are just starting or aiming to strengthen your planning skills, understanding how to build and use logic models is an invaluable part of your learning journey.

Before diving into logic models, it’s crucial to grasp the theory of change. This is the foundational thinking that guides programme design. It outlines the long-term goals you aim to achieve and the steps, both direct and indirect, required to reach them.
The theory of change explains why and how a particular intervention is expected to work. It highlights the assumptions, external factors, and causal pathways that shape your project. By clarifying these elements early, you create a roadmap that informs all subsequent decisions, including your logic model.

A logic model is a structured representation of your programme. Think of it as a visual summary that shows how your inputs (resources) lead to activities, which in turn produce outputs, outcomes, and eventually, long-term impact.
Core components of a logic model:
Inputs: The resources, such as funding, staff, or materials, that support your work.
Activities: The tasks or actions carried out, like training workshops or awareness campaigns.
Outputs: The immediate results of those activities—typically quantifiable.
Outcomes: The short- to medium-term changes in behaviour, knowledge, or condition.
Impact: The long-term change your programme hopes to achieve.
Logic models help bring structure to your planning process. They make it easier to set indicators, measure progress, and communicate your strategy to stakeholders. To explore the broader purpose and methods behind effective monitoring, see Understanding the Fundamentals: What is Monitoring and Evaluation.
Although often used together in programme planning, logic models and the theory of change are distinct tools that serve complementary purposes. Understanding the difference is key to using both effectively.
A theory of change is a high-level narrative or visual representation that explains why and how a desired change is expected to happen. It focuses on the broader context and lays out the causal linkages between the intervention and long-term outcomes. The emphasis is on assumptions, external influences, and underlying rationale.
A logic model, on the other hand, is a more structured and linear tool that shows how a programme will operate to produce specific results. It translates the broad logic of the theory of change into a detailed roadmap of inputs, activities, outputs, outcomes, and impact.
The theory of change is conceptual and strategic, often developed early in the programme design process. It answers the question: “What change are we trying to achieve, and what needs to happen for that to be possible?”
The logic model is operational and tactical. It is often used in planning, implementation, and evaluation phases to track progress and performance. It asks: “What are we doing, with what resources, and what will we produce?”
Theory of Change includes:
Long-term goals
Intermediate outcomes
Preconditions and assumptions
External factors and risks
Evidence-based or rationale
Logic Model includes:
Inputs (resources)
Activities (what you do)
Outputs (direct deliverables)
Outcomes (short- and medium-term changes)
Impact (long-term result)
Use a theory of change to:
Align stakeholders on vision and purpose
Map out pathways of change
Examine contextual influences
Justify your intervention logic
Use a logic model to:
Plan implementation steps
Assign responsibilities
Define performance indicators
Monitor progress and report on results
Imagine a public health initiative aiming to reduce adolescent smoking rates:
The theory of change might explore how increased awareness, better access to counselling, and stricter school policies will lead to a reduction in smoking. It outlines the broader societal and behavioural changes required, including assumptions such as community support or funding stability.
The logic model would then detail:
Inputs: Trained facilitators, funding, educational materials
Activities: School workshops, media campaigns, one-on-one counselling
Outputs: Number of workshops held, attendees reached
Outcomes: Increase in knowledge, change in attitudes
Impact: Measurable drop in smoking rates among adolescents

Creating a logic model may seem daunting at first, but breaking it into clear steps helps simplify the process. Whether you're developing a new programme or refining an existing one, this guide will help you map out your logic model with confidence.
Begin by defining your ultimate impact. What long-term change is your programme aiming to achieve? This could include a reduction in disease rates, improved educational outcomes, or enhanced community well-being.
Next, determine the short- and medium-term outcomes that will lead to your desired impact. These outcomes should reflect the behavioural, knowledge, or systemic changes expected over time.
Think about what tangible products or services your activities will deliver. Outputs are immediate, countable results—such as training sessions conducted, reports produced, or individuals reached.
Detail the key actions and interventions you’ll implement to achieve your outputs and outcomes. Examples include conducting surveys, running workshops, or distributing materials.
Outline the resources needed to carry out these activities. This includes funding, staff, equipment, time, and partnerships.
Finally, determine how you’ll measure success at each stage. Choose clear indicators for inputs, outputs, outcomes, and impact. Ensure they follow the SMART criteria (Specific, Measurable, Achievable, Relevant, and Time-bound).
Even with a solid structure, logic models can fall short if common challenges are not addressed. Here are key pitfalls to watch out for—and how to avoid them:
The pitfall: Attempting to include every possible detail can result in an overly complex model that’s difficult to use or understand.
Avoid it by: Focusing on key components that directly support your programme goals. Keep it simple, logical, and purposeful.
The pitfall: Outcomes that are too broad or abstract make it difficult to track progress or demonstrate success.
Avoid it by: Using clear, specific language and aligning outcomes with measurable indicators. Always ask: How will we know if this has been achieved?
The pitfall: Activities that don’t clearly lead to the intended changes can create gaps in your logic.
Avoid it by: Ensuring each activity has a logical link to an output and outcome. Each step should flow naturally to the next.
The pitfall: Overlooking the context in which your programme operates can lead to unrealistic expectations.
Avoid it by: Identifying and documenting assumptions, risks, and external influences early in the design process.
The pitfall: Building the model in isolation can result in limited buy-in or missed perspectives.
Avoid it by: Engaging stakeholders, including implementers and beneficiaries, throughout the development process to ensure relevance and shared understanding.
