2.2 Theory of Change

Once you have decided where you’re going, you need to figure out how to get there. A theory of change explains “how and why the program will work.”1 It describes how your program will help you get from where you are to your desired outcomes in both narrative and graphic formats. A theory of change can be messy, recursive, and multidimensional, just like reality.2 A different approach is to create a logic model, in which the “how and why” are broken down into components arranged in a more logical order. Connell and Kubisch3 describe a good theory of change as plausible, doable, and testable. In either case, work backwards from your outcomes until you reach the specific activities that will begin the change you want to see.
