Theory of Change Designer
Build validated theories of change with structured assumption mapping
What You Can Do
You can develop rigorous, evidence-based theories of change by working through structured workflows that map causal pathways, surface assumptions, and identify critical evidence gaps. The skill helps you validate key assumptions before implementation, create alignment across stakeholders, and document logic models that withstand scrutiny from donors and evaluators.
Features
Step-by-step guidance through defining problems, interventions, assumptions, and outcomes with interconnected causal logic
Identifies all underlying assumptions in your logic model and prioritizes which ones pose the highest risk to success
Specifies exactly what data, indicators, or proof points you need to validate each causal link in your theory
Surfaces potential failure points, external threats, and implementation risks with structured mitigation strategies
Generates discussion guides and feedback templates to test your theory across program teams and community partners
Outputs structured causal pathway diagrams and matrices ready for presentations, proposals, and evaluation plans
Produces polished theory of change narratives and visual logic models suited for grant proposals and annual reports
Example Output
Theory of Change Summary
Problem: High school students in underserved communities lack skills and confidence for college applications.
Intervention: 12-week intensive mentorship program pairing students with trained college mentors.
Assumed Causal Pathway:
- Regular 1-on-1 mentoring → increased college knowledge and confidence → higher completion of applications → increased college enrollment
Assumption Risk Matrix
| Assumption | Risk Level | Validation Strategy |
|---|---|---|
| Mentors can be trained to guide applications | Medium | Pre-program assessment of mentor readiness; pilot feedback |
| Students will attend 80% of sessions | High | Establish transportation support; track attendance weekly |
| College knowledge improves student confidence | Medium | Pre/post confidence surveys; mentor relationship quality tracking |
Evidence Requirements
- Mentor training completion (process indicator)
- Student attendance rate (implementation indicator)
- Pre/post knowledge assessments (learning outcome)
- College application completion rate (behavioral outcome)
- College enrollment verification (impact outcome)
