What a Theory of Change Does for a Quebec Nonprofit
A funder reading your grant application is looking for one precise thing: the logic that connects your activities to a real change. Centraide du Grand Montréal has published its own theory of change, a compass built around four levers (the partner network, the investment approach, knowledge, influence on public policy) and four fields of action, from youth success to the social fabric [7]. A funder who structures its own strategy this way will likely read your applications through the same lens.
The Annie E. Casey Foundation frames the value differently. A well-built theory of change helps a team clarify its goals, name its assumptions about equity, clarify who decides what, and make measurement and learning possible [2]. These are governance questions.
For the team, the tool solves a more down-to-earth problem: no longer telling ten different versions of the same mission. Esplanade Québec presents it as the bridge between the business model and the impact strategy, useful for connecting strategic planning to measurement and for choosing the indicators that actually matter, rather than the ones that are easy to count [8]. The board, for its part, gets a reference text to anchor to when a new executive director arrives, or when a funder asks the uncomfortable question: why do you believe this will work?
Theory of Change or Logic Model: The Difference
The two terms often circulate as synonyms. They do not cover the same ground. The W.K. Kellogg Foundation Logic Model Development Guide was written to help organizations document how a program links its resources, activities and results, in a fairly linear sequence: inputs, activities, outputs, outcomes [4]. It is a management and accountability tool.
A theory of change goes after the “why.” The Center for Theory of Change defines it as a complete description of how and why a desired change should happen in a given context. The method starts from the long-term goals and works backward, step by step, toward every condition that must be in place to reach them: “backward mapping” [1]. The logic model answers what and how. The theory of change answers why, and documents the assumptions that hold the whole thing up.
| Logic Model | Theory of Change | |
|---|---|---|
| Central question | What and how | Why |
| Logic | Sequential, linear | Causal, with explicit assumptions |
| Usual scope | A single program | A mission, sometimes an entire system |
| Mainly used to | Manage, document, report | Argue a case, test assumptions, align partners |
| Quebec example | A program’s accountability grid | Centraide du Grand Montréal’s theory of change [7] |
In practice, organizations that do both well build the theory of change first, then derive a logic model for each program.
The Steps to Build a Theory of Change
1. Name the problem and the population affected. Name the precise problem you are addressing and who lives it, rather than the whole mission. Esplanade Québec places this step first in its framework: analyzing the issue before talking about solutions [8].
2. Set the long-term impact goal. The change you are aiming for in five or ten years, framed as a state of the world to reach. This is the endpoint of the Center for Theory of Change’s backward mapping [1].
3. Work back up the results chain. Starting from the intended impact, step backward: what medium-term results need to happen before it, what short-term results before that. Each level becomes a necessary condition for the next.
4. Document the assumptions. For every arrow in the diagram, write the sentence “if… then…, provided that…”. This is the move that sets a theory of change apart from a simple activity flowchart, and the one that practical guides like the Annie E. Casey Foundation’s ask you to spell out in writing, not just in leadership’s head [2].
5. Connect the activities to the conditions. Only now, list what the organization actually does, and check that each activity feeds at least one of the conditions identified in step 3. If there are activities that feed nothing, the question to ask is simple: why are we still doing them?
6. Validate with the people involved. The team, the board, program participants, sometimes funders. Communagir stresses this point for any collective planning process: an exercise done alone in an office rarely produces a document people actually buy into afterward [9].
7. Put it all into a diagram. A one-page diagram or table. Nesta presents it, in fact, as a framework that is usually drawn as a diagram or a flow chart [3].
Fictional Example: A Food Security Community Organization in Sherbrooke
This example is entirely fictional. It is used to illustrate the method.
Le Garde-Manger solidaire is a fictional Sherbrooke organization that distributes food and runs cooking workshops in a neighbourhood where many families struggle to make it to the end of the month without cutting back on groceries. Here is its fictional theory of change, built by working backward from impact to activities.
| Level | Content (fictional example) |
|---|---|
| Long-term impact | Families in the neighbourhood have stable access to sufficient, nutritious food, without depending on emergency food aid |
| Medium-term outcome | Participating households increase their food self-sufficiency: they cook more from raw ingredients and manage their grocery budget better |
| Short-term outcome | Participants gain culinary and budgeting skills, and build connections with other families in the neighbourhood |
| Causal hypothesis | If people have access to fresh food, hands-on workshops and a support network, and if their income does not deteriorate further, then they develop lasting food self-sufficiency |
| Activities | Weekly food distribution, collective cooking workshops, community garden, individual budget coaching |
| Population affected | Low-income single-parent families and individuals in the neighbourhood served |
The community garden, on its own, would not make sense in this table. Connected to the causal hypothesis, it becomes a logical link: access to fresh food, skills, social connection. That is exactly the test from step 5 above.
Common Mistakes
The most common one is excess linearity, more a habit of thought than a flaw in execution. Geoff Mulgan, of Nesta, names it directly: theories of change tend to be far too linear, assuming inputs mechanically lead to outputs, and outputs to outcomes, when social phenomena like poverty or isolation follow no straight line [10].
Second trap: a single theory that claims to explain everything. Mulgan puts it bluntly: no working model relies on one theory alone, every one is an assemblage of several elements and several theories [10]. A community organization that reduces its intervention to a single arrow of causality is exposed the moment a funder asks one more question.
Third trap, quieter: a document that stops moving after its presentation to the board. Communagir makes this point for any collective planning exercise: a frozen plan quickly stops being useful, it needs to adapt as the context changes [9]. A theory of change that has been sitting in a drawer for three years does not guide anyone anymore.
Fourth trap: skipping the assumptions step to jump straight to indicators. Without the “if… then…,” indicators end up measuring activities and lose sight of the change. The team ends up producing attendance statistics without ever knowing whether attendance is actually moving them closer to the intended impact.
From Model to Measurement: Indicators and the Data Collection Plan
Once the results chain is in place, each level calls for one or two indicators. A short-term outcome like gaining culinary skills is measured with a simple indicator: the number of participants who complete a workshop, or a before-and-after test on specific knowledge. A medium-term outcome like food self-sufficiency needs a more composite indicator, often a survey repeated over time with the same households.
The data collection plan then answers four concrete questions: who collects the data, how often, with what tool, and who reviews it afterward. A paper form filled out on the way out of a workshop is useless if no one compiles it before the next annual report. The theory of change says what to measure. The data collection plan says who handles it on a Tuesday morning.
The classic mistake at this stage: trying to measure everything because the funder might ask for it. An organization that tracks twenty-five indicators ends up analyzing none of them seriously. Two or three indicators tracked rigorously at each level of the chain, explicitly linked to the causal hypothesis documented in step 4, work better.
FAQ
How long does it take to build a theory of change? It depends on the size of the organization and the number of programs to cover. An exercise for a single program can sometimes wrap up in a few weeks of actual work, spread over two months to leave room for consultations. An exercise covering an organization’s whole mission across several programs takes longer.
Who needs to be involved? The executive director and the board, at minimum, because they are the ones who will refer back to it. The team delivering the activities, because they know what is really happening on the ground. Communagir also stresses involving the people affected by the intended change [9].
Do you need an outside consultant? Not necessarily. A small organization with a single program line can run the exercise internally with one of the guides cited in this article. A consultant becomes useful when the organization has several overlapping programs, when leadership lacks perspective on its own work, or when the board wants an outside view before a strategic planning process.
What is the difference from a strategic plan? The strategic plan answers what the organization will do over the next three years, with a timeline and priorities. The theory of change answers why those actions should produce the intended change. A good strategic plan builds on a theory of change that is already clear; it does not replace it.
Do funders require it? Some name it explicitly on their forms, others ask for a “logic model” or an “intervention logic,” which amounts to the same exercise under a different name. Centraide du Grand Montréal has built its own institutional theory of change, which gives a good sense of the language expected in the applications it receives [7].
Does a small organization with two employees really need one? Yes, in a short version. The full exercise with workshops and multiple rounds of validation is not necessary for a two-person organization. But naming the problem, the long-term goal and the results chain on a single page remains useful, if only to answer the same question the same way twice.
How often should a theory of change be redone? Not with every grant application. A light revision at each strategic planning cycle, and a more complete overhaul if the mission, the context or the population served changes significantly.
Michele Musci works with Quebec nonprofits and foundations to build their theory of change through the FILO package “Theory of Change and Measurement Framework,” an eight-week mandate that delivers a documented theory of change, indicators linked to each level of the results chain, and a data collection plan ready to put into action. To see if the exercise makes sense for your organization, a discovery call is a no-commitment way to discuss it.
