Lesson 9 of 12: Synthesis
The Evidence Map
Interviews produce conversation. Decisions need evidence. The bridge between them is the Evidence Map, a structured artifact with three components that translates raw conversations into something engineering, design, and leadership can act on.
The Three Components
1. Who They Are
Not a full persona with hobbies and favorite colors. A focused characterization of the attributes that make this user type relevant:
- Role and team context
- Tenure with the product
- Usage patterns (frequency, features used, recency)
- Secondary attributes that produced meaningful variation (company size, platform, geography)
2. What Problem They Have
This is the component most teams underinvest in. It requires:
- Problem severity, does it change behavior? Cost time? Money? Emotional energy?
- Alternatives and workarounds, what are users doing today to cope?
3. What Success Looks Like
How would users know the problem is solved? Include both:
- Goals, what would change in their workflow? What metric would improve? What emotional state would shift?
- Non-goals, what will this explicitly NOT address? "This onboarding improvement will not cover enterprise SSO configurations."
Non-goals are scope control. Every feature becomes a kitchen sink without them.
Building an Evidence Map from raw interview notes

Raw note
"Participant said tracking compliance is a nightmare. She forwards training emails to herself as reminders and has a spreadsheet she updates manually every week."
A participant describes an elaborate workaround using Google Sheets and Slack reminders. What does this tell you?
