Theory of Change
A theory of change that logically maps “why this activity brings about social change.”
Overview
Theory of Change (ToC) is a framework that maps how an intervention (a business activity) leads to long-term social change (impact), together with the causal chain and underlying assumptions. It grew out of the U.S. social-change literature in the 1990s and is now widely adopted by NPOs, companies, and governments alike. It is the most fundamental framework for designing, measuring, and explaining impact management.
When to use it
- When designing a new business or an initiative on a social issue
- When explaining to investors and stakeholders “why this activity affects society”
- When designing impact-measurement indicators (KPIs)
- When sharing and aligning the business logic within the organization
How to use it
Write in 1–2 sentences “what social change do we ultimately want to create.” This becomes the north star of the ToC.
List the social, institutional, and behavioral conditions required for that impact to be realized.
Working back from the long-term impact, set short-term (1–2 years) and mid-term (3–5 years) outcomes.
Describe the concrete activities and outputs needed to produce each outcome.
A ToC is not made once and finished; update it continuously based on data from practice.
◎ Pros
- ·By making the causal chain and assumptions explicit, weaknesses in the business logic are easier to see
- ·Widely recognized as a tool for explaining to investors, grant-makers, and partners
- ·Functions as a process for deepening shared understanding of “why we do this business”
- ·Connects directly to designing impact-measurement indicators (KPIs)
△ Cautions
- ·Trying to make it perfect takes time; you need the mindset of starting with Draft 1.0
- ·For complex social issues, there is a risk of oversimplifying causality
- ·Verifying the assumptions requires empirical data; early on it is hypothesis-based
