Process Phase

A Logic Model is a great next step after you Explore your Theory of Change activity. It is a succinct and visual narrative that summarizes the final set of activities in your solution, and the way that each of these will lead to change over time. It’s a great way to communicate the rationale behind your solution quickly to others, and a crucial foundation for developing a plan to Monitor and Evaluate your solution later. There are some best practice ways to define and order your activities, milestones, and goals in a logic model. The steps and video below will guide you.


  1. Begin by writing the following on Post-it notes: IMPACT, OUTCOMES, OUTPUTS, AND INPUTS and put them up on the wall. Order them with IMPACT at the top and INPUTS at the bottom.
  2. Now, pull out the Impact Ladder worksheet you completed during your Theory of Change activity. You will see it follows this same basic structure, where you have captured activities (OUTPUTS) to address some key shifts (INTERIM OUTCOMES) to achieve bigger goals (KEY OUTCOME and IMPACT).
  3. Write your various outputs/outcomes on Post-it notes and organize them on your wall at the level they correspond to. Aim for a clear structure, or flow, that visualizes how one thing leads to another. This bit can be a bit complex if you have many solution components, so watch the video below for a guiding example.
  4. You interrogated the logic behind your solution when working on your theory of change. This is a good moment to do it again. Does the logic for how one thing will lead to another hold up? What leaps are we making at each step? Do any steps need to be added in? Capture these, and refine your model.
  5. Be sure to update your Logic Model any time that you make refinements or adaptations to your solution, and reference it closely when you Define Your Indicators for measuring solution effectiveness later.
