The document distinguishes between theories of change and logic models. While the terms are sometimes used interchangeably, they differ in important ways. Logic models (1) illustrate program components visually with inputs, outputs and outcomes, while theories of change (2) explain causally how and why desired changes will occur through necessary preconditions. Theories of change require identifying indicators to show how preconditions must be met before subsequent outcomes. Using both provides the best approach, with a theory of change process informing a summarized logic model to communicate the program to different audiences.
Theories of change and logic models

- 3. TOC vs. Logic Models! What a headache! Terms often used interchangeably Confusion by funders and grantees about expectations Limited knowledge on how to use TOC and LMs can “blend” into each other 3
- 4. …but it is worth the trouble to figure this out… Yet, funders almost all demand one or the other Both can greatly improve program design and evaluation (but in different ways) 4
- 5. So what’s the problem? Everyone talking about TOCs and LMs, but not meaning the same thing Grantees being penalized by confusion when funders not sure Underuse of their power to improve programs Neither term is clearly defined in literature 5
- 6. So, let’s set the record straight … Logic Model - United Way format is most widespread Theory of Change – less standardized, but has core components 6
- 7. ..and for the history buff: Logic Models 30 year history Clear identification of goals (outcomes) First widespread attempt to depict program components so that activities matched outcomes 7
- 8. What is a logic model? Inter- mediate Long-term Inputs Activities Outputs Outcomes Outcomes 8 Basic United Way format, 1996
- 9. Theories of Change Popularized in 1990s to capture complex initiatives Outcomes-based Causal model Articulate underlying assumptions 9
- 10. What is a Theory of Change? Long-term Explain WHY here Outcome Show activities here Necessary Necessary also Pre- Pre- All condition condition outcomes that must be Necessary Necessary Necessary achieved Pre- Pre- Pre- BEFORE condition condition condition long-term 10
- 11. Let’s Look at an Example Project Superwomen 11
- 12. How are they different? Logic models graphically illustrate program components, and creating one helps stakeholders clearly identify outcomes, inputs and activities Theories of Change link outcomes and activities to explain HOW and WHY the desired change is expected to come about 12
- 13. How are they different? (1) Logic Models usually start with a program and illustrate its components Theories of Change may start with a program, but are best when starting with a goal, before deciding what programmatic approaches are needed 13
- 14. How are they different? (2) Logic Models require identifying program components, so you can see at a glance if outcomes are out of sync with inputs and activities, but they don’t show WHY activities are expected to produce outcomes Theories of Change also require justifications at each step – you have to articulate the hypothesis about why something will cause something else (it’s a causal model, remember!) 14
- 15. How are they different? (3) Logic Models don’t always identify indicators (evidence to measure whether outcomes are met or not) Theories of Change require identifying indicators WHY DOES THIS MATTER? 15
- 16. How are they different? Because, you need to know HOW WELL a precondition needs to be met in order to get to the next goal. What does that mean? Example: How often do students need to attend the after-school program in order for their reading tests scores to improve? 16
- 17. How are they different? A Logic Model would tell you that the after school program is an activity and improved reading scores is an outcome. It might tell you that attendance at the after school program is an intermediate outcome. 17
- 18. How are they different? But it wouldn’t tell you that: “students need to attend after-school programs at least 3 days per week for a minimum of 60 days, and the curricula must focus on love of reading and literacy, IN ORDER FOR test scores to rise” 18
- 19. How are they different? Summary Logic Models Theories of Change Representation Critical Thinking List of Components Pathway of Change Descriptive Explanatory 19
- 20. When to Use? Logic Models are great when you need to: Show someone something they can understand at a glance Demonstrate you have identified the basic inputs, outputs and outcomes for your work Summarize a complex theory into basic categories 20
- 21. When to Use? Theories of Change are best when you need to: Design a complex initiative and want to have a rigorous plan for success Evaluate appropriate outcomes at the right time and the right sequence Explain why an initiative worked or did not work, and what exactly went wrong 21
- 22. It’s obvious by now: Theories of Change are a lot of work and take time. On the other hand, Logic Models are often too simplistic to be helpful….. 22
- 23. So, can we have the best of both worlds? We suggest, Undertake a TOC process that is a manageable scope for your organization. Make sure you get stakeholders to articulate what has to happen IN ORDER for goals to be met and their assumptions about why…. 23
- 24. Then, Summarize your theory in ways that serve the purposes of your different constituents, such as residents, funders, Boards, etc. A Logic Model that is a summary of an underlying theory is a much more powerful tool. 24
