Diagnostic Toolkit

Use this lightweight toolkit to triage issues before you invest in builds.

Master diagnostic 

Problem unclear → Run Problem Validation Interviews → Evidence of active solution seeking?
  └─ No → Strengthen Problem Fit first
  └─ Yes → Behavior unclear → Run Behavioral Observation → Will users perform behavior in context?
       └─ No → Choose a different behavior or change context
       └─ Yes → Prototype solution → Time to first behavior acceptable?
            └─ No → Reduce friction and steps
            └─ Yes → Verify Product Fit and unit economics
