§ 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:

• Outcome impact (which opportunity affects the metric most?)
• Evidence strength (how many customers mentioned this?)
• 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
