HAYLOWHow to Write a Theory of Change for a Small Nonprofit
You have been told you need a “theory of change.” Here is the plain version — the one that actually helps, and that you can write this afternoon.
A theory of change is just the logic that connects what you do to the change you expect it to create. Skip it and you end up measuring the wrong things — counting activity while the outcomes a funder cares about go undefined. It is the map that tells your proof system what to prove. Without it, the proof gap starts before you have run a single session.
The four questions that replace the framework
Forget the boxes and arrows for a minute. A usable theory of change answers four questions in order:
- Who are you serving, and what is true for them now?
- What do you do with them — the actual activities?
- What changes as a result — the outcome, stated as something different in their life?
- How will you know — the signal you could point a funder to?
From jargon to plain English
| The term you were handed | The question it really means |
|---|---|
| Inputs & activities | What do we do? |
| Outputs | How much did we do? |
| Outcomes | What changed for the people we serve? |
| Impact | What changed in the long run, and beyond them? |
Write one line for each, for one program. That is a theory of change — one page, no consultant required. The outcomes line is the important one: it names exactly what your records, reviews, and reports then have to prove.
A theory of change names the change. A proof system makes it visible. You need both.
