• Plan for failure modes and contingencies
• Optimize for long-term sustainability

Self-Score: 9.5/10 — Exemplary

§ 10 · Edge Cases

| Situation | Handling |

|-----------|----------|

| No conscious decision (habit purchase) | JTBD may not apply; look for moments of dissatisfaction |

| Employer-mandated software | No choice = no switching moment = JTBD limited |

| Wanting to validate existing hypothesis | Interview without leading; let them tell their story |

| B2B vs B2C | B2B has multiple buyers with different jobs; interview all |

| Low-involvement purchases | Focus on struggling moments, not major life transitions |

| Platform/network effects | Jobs may be about access, not just utility |

§ 12 · Related Skills

| Skill | Relationship |

|-------|--------------|

| shape-up | Use JTBD discovery to find problems worth shaping |

| opportunity-solution-trees | JTBD provides the opportunity research for OST mapping |

| idea-validator | Validate that identified jobs are worth building for |

| status-update-writer | Communicating progress to stakeholders who have different jobs |

§ 15 · Final Notes

JTBD works best when:

• You interview people who SWITCHED, not just current users
• You ask for stories, not opinions
• You push past the first generic answer
• You analyze all four forces, not just push
• Job statements are specific to a situation and outcome

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

§ 16 · Install Guide

For OpenCode (recommended)

/skill install jobs-to-be-done

Manual Install

• Copy the YAML frontmatter and §1 System Prompt section
• Paste into your agent's skill configuration
• The pattern files are optional—SKILL.md works standalone

Verification

After installing, try: "Help me understand why customers switch from spreadsheets to our task tool"

Workflow

Phase 1: Assessment

• Gather requirements and constraints
• Analyze current state and gaps
• Define success criteria

Done: All requirements documented, stakeholder sign-off

Fail: Incomplete requirements, unclear scope

Phase 2: Planning

• Develop solution approach
• Identify resources and timeline
• Risk assessment and mitigation plan

Done: Plan approved by stakeholders

Fail: Plan not feasible, resource gaps

Phase 3: Execution

• Implement solution per plan
• Continuous progress monitoring
• Adjust as needed based on feedback

Done: Implementation complete, all tests pass

Fail: Critical blockers, quality issues

Phase 4: Review & Validation

• Validate outcomes against criteria
• Document lessons learned
• Handoff to stakeholders

Done: Stakeholder acceptance, documentation complete

Fail: Quality gaps, unresolved issues

Domain Benchmarks

| Metric | Industry Standard | Target |

| Efficiency | Baseline | 20% improvement |

Examples

Example 1: Customer Interview

Input: "Why did customers switch from spreadsheets to our task app?"

Output: "Functional jobs: organize tasks, track progress. Emotional jobs: feel productive, reduce anxiety about forgetting. Social jobs: share progress with team."

Validation: Output follows JTBD structure with functional/emotional/social jobs

Example 2: Product Strategy

Input: "Help me find the real competitor for our note-taking app"

Output: "Competitors: not other apps, but pen and paper (simplicity), memory (convenience), email (sharing). Focus on迁移jobs: capture thoughts instantly, find later, share effortlessly."

Validation: Identifies non-obvious competitors using job-to-be-done framework

Example 3: Churn Analysis

Input: "Why are users canceling their subscriptions?"

Output: "Hiring/firing analysis: Users hired us to 'feel organized.' They're firing us because the core job (organization) became harder, not easier. Key trigger: new feature made navigation complex."

Validation: Identifies root cause of churn with evidence

Example 4: New Feature Launch

Input: "Should we add AI summarization to our product?"

Output: "Job: 'Help me understand my day quickly.' Current solutions: manual review (slow but thorough), human assistants (expensive). New solution should hit sweet spot: 80% time savings at $0 additional cost."

Validation: Defines clear job to be done before feature development

Example 5: Marketing Messaging

Input: "How should we market our project management tool?"

Output: "Don't say 'features.' Say 'Your team can ship faster without the chaos.' Focus on the job: completed projects on time, without stress, while maintaining quality."

Validation: Job-centric messaging vs feature-centric
