§ 10 · Example Interactions

User: "We want to build a better onboarding flow."

Assistant: "Let's frame this as an OST. First question: What's the outcome?

Bad outcome: 'Better onboarding' Good outcome: 'Increase week-2 retention from 40% to 55%'

Now let's find the opportunities from customer research. Interview users about:

• 'Walk me through your first time using the product'
• 'What was hard to figure out?'
• 'What did you wish was easier?'

The OST would look like:

Outcome: Week-2 retention 40% → 55%

└── Opportunity: Users don't understand value quickly
    ├── "Don't know what to do first"
    ├── "Can't find the main feature"
    └── "Setup feels overwhelming"
        ├── Solution A: Interactive tutorial
        ├── Solution B: Guided first project
        └── Solution C: Onboarding checklist
            → Experiment: Fake door for checklist

Which opportunity should we decompose first?"

---

User: "How do we prioritize between multiple opportunities?"

Assistant: "The OST doesn't prioritize—it visualizes. Prioritization comes from:

1. Outcome impact (which opportunity affects the metric most?)
2. Evidence strength (how many customers mentioned this?)
3. Solution feasibility (can we test this quickly?)

Use your weekly customer interviews to validate which opportunities matter most, then focus there."

§ 11 · Edge Cases

Situation	Handling
No customer research capacity	Start small: 1 interview/week still builds the tree
Stakeholders want one solution	Show all 3+ options; force comparison, not assumption
Opportunities span multiple teams	One OST per team or product area, connected to shared outcome
Solutions overlap across opportunities	That's fine—solutions often address multiple needs
Experiment fails	Update the tree; failed experiments are learnings
No prior JTBD work	Pair with jobs-to-be-done for opportunity identification

§ 15 · Final Notes

OST works best when:

• You interview customers weekly (even 1 per week counts)
• You capture stories, not survey answers
• You generate multiple solutions, not default to the first idea
• You test assumptions, not whole solutions
• The tree is updated continuously, not built once

Full pattern files with worked examples are available in the source repository.

Examples

Example 1: Building OST

Input: "Help me build an Opportunity Solution Tree for reducing cart abandonment" Output: "Outcome: Reduce cart abandonment from 70% to 55%. Opportunity 1: Users uncertain about security - Solution: trust badges, security info. Opportunity 2: Shipping costs too high - Solution: free shipping threshold. Opportunity 3: Need to create account - Solution: guest checkout." Validation: Clear outcome metric, 3+ opportunities with solutions

Example 2: Prioritizing Opportunities

Input: "We have 12 opportunities in our OST. How do we pick which to build?" Output: "Rate each by: 1) Job to be done frequency (how often do users face this?), 2) Current satisfaction gap (how unhappy are they?), 3) Market size (how many users?). Plot on impact/effort matrix." Validation: Framework for prioritization provided

Example 3: Experiment Design

Input: "Design an experiment for our top solution" Output: "Solution: Guest checkout button. Hypothesis: Adding guest checkout will increase conversions by 15%. Experiment: A/B test - 50% see guest option, 50% require account. Success metric: completed purchases. Duration: 2 weeks or 10K visitors." Validation: Clear hypothesis, metric, and success criteria
