| 4 | |
| 5 | This skill covers the **Delivery System** — how we ship, measure, and learn. It runs discovery and delivery in parallel (dual-track), ships with staged rollouts, measures with a clear hierarchy, reflects through retrospectives, and executes GTM with precision. |

| 13 | ## When to Use This Skill |
| 14 | |
| 15 | Use this skill when: |
| 16 | - Planning how to roll out a new feature or product |
| 17 | - Designing a metrics hierarchy for a bet or product |
| 18 | - Running bet retrospectives after shipping |
| 19 | - Executing GTM launches |
| 20 | - Setting up dual-track development rhythm |
| 21 | - Deciding when to scale, iterate, or kill a bet |
| 22 | |
| 23 | **Cadence**: Continuous | **Owner**: Product Trio + GTM Team |

| 27 | ## The Problem This Solves |
| 28 | |
| 29 | Most teams either: |
| 30 | 1. Ship features and never measure impact |
| 31 | 2. Measure vanity metrics that don't connect to outcomes |
| 32 | 3. Do "big bang" launches that create risk |
| 33 | 4. Never officially conclude bets—zombies live forever |
| 34 | 5. Treat GTM as marketing's problem after PM ships |
| 35 | |
| 36 | The Delivery System ensures **shipping is the beginning of learning, not the end**. |

| 40 | ## Philosophy |
| 41 | |
| 42 | ### Core Beliefs |
| 43 | |
| 44 | 1. **Discovery and delivery run in parallel** — Don't pause discovery to deliver |
| 45 | 2. **Staged rollouts are the default** — Ship to 10% before 100% |
| 46 | 3. **Metrics exist in hierarchy** — Leading → Core → Lagging |
| 47 | 4. **Every bet gets a retrospective** — Explicit scale/iterate/kill decision |
| 48 | 5. **GTM is a product responsibility** — PM owns adoption, not just availability |
| 49 | |
| 50 | ### What This Framework Rejects |
| 51 | |
| 52 | - Ship and forget (no measurement) |
| 53 | - Big bang launches (maximum risk) |
| 54 | - Vanity metrics (activity without outcome) |
| 55 | - Zombie bets (never concluded, never killed) |
| 56 | - Throwing features over the wall to marketing |

| 60 | ## Framework Components |
| 61 | |
| 62 | ### 1. Dual-Track Development |
| 63 | |
| 64 | **The Core Idea:** |
| 65 | Discovery and delivery happen simultaneously. While one bet is being built, the next bet is being shaped. |
| 66 | |
| 67 | ``` |
| 68 | Week 1 Week 2 Week 3 Week 4 Week 5 Week 6 |
| 69 | ───────────────────────────────────────────────────────── |
| 70 | [ Discover Bet B ][ Shape Bet B ][ Discover Bet C ] |
| 71 | [ Build Bet A ][ Build Bet B ] |
| 72 | [ Ship A ] [ Ship B ] |
| 73 | ``` |
| 74 | |
| 75 | **How It Works:** |
| 76 | |
| 77 | | Track | Activities | Who | |
| 78 | |-------|------------|-----| |
| 79 | | **Discovery Track** | Interviews, OST updates, solution exploration, assumption tests | Full trio (PM heavy) | |
| 80 | | **Delivery Track** | Building, testing, shipping, measuring | Full trio (Eng heavy) | |
| 81 | |
| 82 | **Time Allocation (Example):** |
| 83 | |
| 84 | | Role | Discovery | Delivery | |
| 85 | |------|-----------|----------| |
| 86 | | PM | 60% | 40% | |
| 87 | | Designer | 50% | 50% | |
| 88 | | Tech Lead | 30% | 70% | |
| 89 | |
| 90 | **Coordination Points:** |
| 91 | - **Weekly sync**: What's in flight on each track |
| 92 | - **Handoff moment**: When a bet moves from "shaped" to "building" |
| 93 | - **Learning moment**: When shipped bet results inform discovery |
| 94 | |
| 95 | **0→1 Mode**: Tracks may blur. Everyone does everything. Speed > separation. |
| 96 | |
| 97 | **Scaling Mode**: Clear separation. Dedicated discovery time. Research ops support. |

| 101 | ### 2. Staged Rollout |
| 102 | |
| 103 | **The Core Idea:** |
| 104 | Never ship to everyone at once. Start small, learn, expand. |
| 105 | |
| 106 | **Default Rollout Stages:** |
| 107 | |
| 108 | | Stage | Audience | Duration | Purpose | |
| 109 | |-------|----------|----------|---------| |
| 110 | | **Stage 0: Internal** | Team dogfooding | 1-3 days | Find obvious bugs | |
| 111 | | **Stage 1: Alpha** | 5-10 friendly customers | 1 week | Qualitative feedback | |
| 112 | | **Stage 2: Beta** | 10% of users | 1-2 weeks | Quantitative signal | |
| 113 | | **Stage 3: GA** | 100% of users | Ongoing | Full measurement | |
| 114 | |
| 115 | **Progression Criteria:** |
| 116 | |
| 117 | | From | To | Criteria | |
| 118 | |------|----|----------| |
| 119 | | Internal → Alpha | Ready for external | No P0 bugs, core flow works | |
| 120 | | Alpha → Beta | Validated experience | Positive qualitative feedback, no major usability issues | |
| 121 | | Beta → GA | Metrics acceptable | Leading metrics trending right, no guardrail breaches | |
| 122 | |
| 123 | **Feature Flags:** |
| 124 | - Every significant feature ships behind a flag |
| 125 | - Flags enable instant rollback |
| 126 | - Flags enable % rollout control |
| 127 | - Flags are cleaned up after GA (don't accumulate debt) |
| 128 | |
| 129 | **Rollback Triggers:** |
| 130 | - Guardrail metric breached |
| 131 | - Error rate > threshold |
| 132 | - Customer-reported critical issue |
| 133 | - Leading metrics trending wrong |
| 134 | |
| 135 | **0→1 Mode**: Stages can be compressed. Alpha might be 3 customers for 2 days. |
| 136 | |
| 137 | **Scaling Mode**: Formal stage gates. Release manage |
