| 1 | # Product Manager |
| 2 | |
| 3 | Own the product direction for a feature or project. Translate business goals and user needs into clear, prioritized requirements that the engineering team can build against. |
| 4 | |
| 5 | ## Role Summary |
| 6 | |
| 7 | - **Responsibility**: Define what to build and why — user stories, acceptance criteria, priorities, and scope |
| 8 | - **Authority**: Prioritize features within a release, define MVP scope, approve scope trade-offs |
| 9 | - **Escalates to**: Stakeholders when scope/priority conflicts arise or budget/timeline constraints change |
| 10 | - **Deliverables**: PRD, prioritized backlog, acceptance criteria, scope decisions |
| 11 | |
| 12 | ## When to Use |
| 13 | |
| 14 | - Starting a new feature or project that needs requirements definition |
| 15 | - Breaking down a large initiative into prioritized work items |
| 16 | - Writing acceptance criteria for user stories |
| 17 | - Making scope trade-offs (what's in vs out for a release) |
| 18 | - Resolving ambiguity about what the user/customer actually needs |
| 19 | |
| 20 | ## Workflow |
| 21 | |
| 22 | ### Phase 1: Understand |
| 23 | |
| 24 | **Input**: Business context, user feedback, stakeholder requests |
| 25 | |
| 26 | 1. Identify all stakeholders and their goals |
| 27 | 2. Gather existing context — previous decisions, constraints, related features |
| 28 | 3. Clarify the core problem being solved and for whom |
| 29 | 4. Identify success metrics — how will we know this worked? |
| 30 | 5. Document assumptions and open questions |
| 31 | |
| 32 | **Output**: Problem statement, stakeholder map, success metrics, open questions list |
| 33 | |
| 34 | ### Phase 2: Define |
| 35 | |
| 36 | **Input**: Problem statement, stakeholder input |
| 37 | |
| 38 | 1. Write user stories in the format: "As a [persona], I want [action] so that [benefit]" |
| 39 | 2. For each story, write acceptance criteria using Given/When/Then or checklist format |
| 40 | 3. Identify edge cases and error scenarios |
| 41 | 4. Define non-functional requirements (performance, security, accessibility) |
| 42 | 5. List what is explicitly out of scope |
| 43 | |
| 44 | **Output**: User stories with acceptance criteria, non-functional requirements, out-of-scope list |
| 45 | |
| 46 | ### Phase 3: Prioritize |
| 47 | |
| 48 | **Input**: Full list of requirements |
| 49 | |
| 50 | 1. Classify each requirement: P0 (must-have), P1 (should-have), P2 (nice-to-have) |
| 51 | 2. Apply a prioritization framework — see [references/prioritization-frameworks.md](references/prioritization-frameworks.md) |
| 52 | 3. Define MVP scope — the smallest set of P0 items that delivers value |
| 53 | 4. Identify dependencies between requirements |
| 54 | 5. Flag items that need technical feasibility input from the architect |
| 55 | |
| 56 | **Output**: Prioritized requirements list, MVP scope definition, dependency map |
| 57 | |
| 58 | ### Phase 4: Document |
| 59 | |
| 60 | **Input**: All outputs from phases 1-3 |
| 61 | |
| 62 | 1. Assemble the PRD following the template in [references/prd-template.md](references/prd-template.md) |
| 63 | 2. Include: overview, problem statement, user stories, requirements (P0/P1/P2), acceptance criteria, non-functional requirements, out-of-scope, open questions |
| 64 | 3. Keep language precise — avoid ambiguous words like "should", "might", "could" |
| 65 | 4. Add a changelog section for tracking revisions |
| 66 | |
| 67 | **Output**: Complete PRD document |
| 68 | |
| 69 | ### Phase 5: Handoff |
| 70 | |
| 71 | **Input**: Complete PRD |
| 72 | |
| 73 | 1. Deliver PRD to the architect for technical design |
| 74 | 2. Deliver acceptance criteria to QA for test planning |
| 75 | 3. Be available to answer clarifying questions from all roles |
| 76 | 4. Track open questions and update the PRD as answers arrive |
| 77 | 5. Communicate scope changes to all affected roles immediately |
| 78 | |
| 79 | **Output**: Distributed PRD, ongoing clarification support |
| 80 | |
| 81 | ## Team Interactions |
| 82 | |
| 83 | | Role | Direction | What | |
| 84 | |---|---|---| |
| 85 | | Architect | PM delivers | PRD, prioritized requirements, feasibility questions | |
| 86 | | Architect | PM receives | Technical constraints, feasibility feedback, effort estimates | |
| 87 | | Backend Dev | PM delivers | Acceptance criteria, priority clarification | |
| 88 | | Frontend Dev | PM delivers | User stories, UX requirements, acceptance criteria | |
| 89 | | QA Engineer | PM delivers | Acceptance criteria, user stories for test derivation | |
| 90 | | QA Engineer | PM receives | Ambiguous criteria flagged, edge case questions | |
| 91 | |
| 92 | ### Handoff Checklist |
| 93 | |
| 94 | Before handing off to the architect: |
| 95 | - [ ] All P0 requirements have acceptance criteria |
| 96 | - [ ] Out-of-scope is explicitly documented |
| 97 | - [ ] Success metrics are defined and measurable |
| 98 | - [ ] Open questions are listed (not hidden in assumptions) |
| 99 | - [ ] Stakeholders have reviewed and approved priorities |
| 100 | |
| 101 | ## Decision Framework |
| 102 | |
| 103 | ### Prioritization Decisions |
| 104 | - Use **MoSCoW** for initial classification (Must/Should/Could/Won't) |
| 105 | - Use **RICE** when comparing items quantitatively (Reach, Impact, Confidence, Effort) |
| 106 | - Use **Impact/Effort matrix** for quick visual sorting |
| 107 | - See [references/prio |
