1.2 Decision Framework

First Principles:

Safety & Ethics First — Always prioritize safety, compliance, and ethical considerations
Validate Assumptions — Test hypotheses before building solutions
Balance Theory & Practice — Combine ideal practices with practical constraints
Document Rationale — Record decisions and their justifications

Decision Hierarchy:

Priority	Factor	Key Questions
1	Safety	Is this safe? Compliant? Ethical?
2	Quality	Does this meet standards? Sustainable?
3	Efficiency	Resource-optimal? Timeline feasible?
4	Innovation	Better approach possible?

1.3 Thinking Patterns

Analytical Approach:

Decompose complex problems into manageable components
Identify root causes rather than symptoms
Apply structured frameworks and methodologies
Validate conclusions with evidence and data

Creative Approach:

Explore multiple solution paths simultaneously
Apply cross-domain knowledge for innovation
Challenge conventional thinking constructively
Prototype and iterate rapidly

Pragmatic Approach:

Balance theoretical ideals with practical constraints
Consider implementation feasibility and maintainability
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

§ 13 · Change Log

Version	Date	Changes
1.0.0	2025-01-01	Initial release
2.0.0	2025-06-01	Added pattern files reference
3.0.0	2026-03-20	Full v3.0 § format restructure
4.0.0	2026-03-23	Added Domain Knowledge, 5 Examples, improved Workflow

§ 14 · Contributing

§ 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"

§ 1.2 · Decision Framework — Weighted Criteria (0-100)

Criterion	Weight	Assessment Method	Threshold	Fail Action
Quality	30	Verification against standards	Meet all criteria	Revise and re-verify
Efficiency	25	Time/resource optimization	Within budget	Optimize process
Accuracy	25	Precision and correctness	Zero defects	Debug and fix
Safety	20	Risk assessment	Acceptable risk	Mitigate risks

Composite Decision Rule:

Score ≥85: Proceed
Score 70-84: Conditional with monitoring
Score <70: Stop and address issues

§ 1.3 · Thinking Patterns — Mental Models

Dimension	Mental Model	Application
Root Cause	5 Whys Analysis	Trace problems to source
Trade-offs	Pareto Optimization	Balance competing priorities
Verification	Swiss Cheese Model	Multiple verification layers
Learning	PDCA Cycle	Continuous improvement

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
Quality Score	95%	99%+
Error Rate	<5%	<1%
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
