Theory of Change: how funders map the path from funding to impact

Definition

A theory of change articulates the logical chain from inputs and activities, through outputs, to outcomes and ultimate impact.

It makes a program's assumptions explicit and defines what should be measured at each step. Funders use it to align grantees around shared goals, and to decide which indicators actually demonstrate impact, rather than measuring whatever is easiest to count.

What is a theory of change?

A theory of change is a funder's articulation of how the grants it makes will produce the outcomes it cares about. It maps the causal path from inputs, money, time and expertise, through activities and outputs, to outcomes and ultimately the longer-term impact the funder is trying to achieve.

At its core it is a causal claim: a hypothesis about cause and effect. It answers the question "why do we believe that funding this kind of work, for this kind of organisation, in this context, will produce the change we want?"

‍

What does a good theory of change include?

A strong theory of change does three things. It identifies the change the funder is trying to achieve, names the intermediate changes required along the path to it, and makes explicit the assumptions that must hold for the pathway to work.

That last element is what separates a theory of change from wishful thinking. By stating the assumptions openly, inputs, animating conditions, external factors, a funder can test whether the logic actually holds as evidence comes in, rather than discovering years later that a hidden assumption never did.

‍

How do funders use a theory of change?

For funders, a theory of change is a design and evaluation tool, not a paperwork exercise. It shapes program design by clarifying what level of intervention is needed, and it shapes evaluation by defining which outcomes are worth measuring in the first place.

Many funders also expect grantees to hold their own theory of change, or to produce one on request, and use it to design reporting that collects evidence on the model, rather than asking for activity metrics that never connect to the outcomes that matter.

‍

Applying a theory of change in a grant platform

A grant management software platform turns a theory of change from a static document into the backbone of measurement. Each intended outcome becomes a KPI that grantees report against, so grantee reporting collects evidence directly on the model rather than on disconnected outputs.

Volunteering

Value of Volunteer Time

The value of volunteer time is an hourly monetary rate applied to volunteer hours in order to express a volunteering programme's contribution in currency terms, used in impact reports and in-kind accounting.

The figure is an estimate, not a payment. It states what those hours would have cost to buy, which makes programmes comparable over time — and says nothing about what the receiving organisation actually gained.

Sponsorship Management

Brand Lift

Brand lift is the measurable change in awareness, consideration or perception of a brand that follows exposure to a sponsorship or campaign, calculated by comparing an exposed audience with a control group that was not exposed.

Lift is a difference, not a total. A brand recognised by 40% of an audience before a sponsorship and 46% after has a six-point lift, and the figure is only credible if both groups were surveyed the same way over the same period.

Program-related Investment (PRI)

A program-related investment (PRI) is an investment a foundation makes primarily to advance its mission rather than to earn a return. Unlike a grant, a PRI is expected to be repaid: it takes the form of a below-market loan, loan guarantee, or equity investment.
