A 'theory of action' focuses on what you can do and build from your current position, while a 'theory of change' works backward from a desired goal state—the latter requires more uncertainty and is harder but more directional than iterative experimentation.

Evidence Quote

A theory of action as opposed to a theory of change is... a theory of action is you look around you and you say, "Well, what can I do? What can I build? What do I see as possible?"... A theory of change is to look at the endpoint to try to work backwards.
