§ 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

1. Copy the YAML frontmatter and §1 System Prompt section
2. Paste into your agent's skill configuration
3. 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

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
