Theory of Change explains the process of change by outlining causal linkages in an initiative, i.e., its shorter-term, intermediate, and longer-term outcomes. The identified changes are mapped – as the “outcomes pathway” – showing each outcome in logical relationship to all the others, as well as chronological flow and feedback loops. The links between outcomes are explained by “rationales” or statements of why one outcome is thought to be a prerequisite for another.
The innovation of Theory of Change lies (1) in making the distinction between desired and actual outcomes and (2) in requiring stakeholders to model their desired outcomes before they decide on forms of intervention to achieve those outcomes.
Let’s take a concrete example. Imagine you want to decrease the size of the defense budget. The typical way you might approach this is to look around at the things you know how to do and do them on the issue of decreasing the defense budget. So, if you have a blog, you might write a blog post about why the defense budget should be decreased and tell your friends about it on Facebook and Twitter. If you’re a professional writer, you might write a book on the subject. If you’re an academic, you might publish some papers. Let’s call this strategy a “theory of action” [Theory of action]: you work forwards from what you know how to do to try to find things you can do that will accomplish your goal.
A theory of change is the opposite of a theory of action — it works backwards from the goal, in concrete steps, to figure out what you can do to achieve it. To develop a theory of change, you need to start at the end and repeatedly ask yourself, “Concretely, how does one achieve that?”
Steps
These steps are based on (“How Does Theory of Change Work?” n.d.). The ordering, with the exception of starting from Goals, is a recommendation as opposed to a hard rule. For instance, you may need to revisit previous steps as you progress if you identify previously unknown flaws or opportunities in your reasoning.
- Goals: Identify and agree upon long term goal(s)
- Outcomes: Create an outcomes framework by Backcasting from long term goal(s) and explain why these preconditions are necessary and sufficient
- Assumptions: Make assumptions explicit
- Evidence: Develop indicators which will measure the outcomes and assess your performance (see OKR)
- Action: Identify your next steps based on the outcome
- Convince: Create a narrative which explains the logic of this plan and use it to convince necessary stakeholders
As compared to a theory of action
Based on (Tyrrel 2019) and (Swartz 2010):
- Theory of action
- Works forward from where you are right now toward the goal
- Focuses on what you will do to try and affect change
