--- name: engineering-initiative-breakdown-generator description: "Decomposes a complex engineering initiative into a phased milestone plan with owners, dependencies, success criteria, effort estimates, risk register, and a rollout/validation strategy. Use when breaking down a large technical project, migration, platform build, or cross-team initiative into an actionable execution plan with clear ownership and measurable outcomes." argument-hint: "[initiative-description] [team-size]" allowed-tools: ["Read"] --- # Engineering Initiative Breakdown Generator ## Purpose Turn a vague, oversized engineering initiative into a phased execution plan — with sequenced milestones, named owners, explicit dependencies, effort estimates, and measurable success criteria — so a team can start work with clear scope and a way to know when each phase is actually done. Eliminates the "big scary project with no starting point" problem. ## When to Use Invoke this skill when the user asks to: - Break down a large engineering project, migration, or platform build into phases - Turn a technical initiative into milestones with owners and success criteria - Plan a cross-team engineering effort or multi-quarter roadmap item - Estimate scope and sequencing for a complex technical undertaking - Create an execution plan for a re-architecture, infrastructure change, or new system - Structure an ambiguous initiative into something a team can actually start on ## Inputs Required Before starting, collect: - **Initiative description**: 2–4 sentences on what's being built or changed and why - **Business/technical driver**: The outcome this initiative must produce (revenue, reliability, unblock, compliance, scale) - **Team composition**: Roles and headcount available (e.g., 3 backend, 1 frontend, 1 SRE) — names if known - **Timeline constraint**: Target completion date or hard deadline, if any - **Known dependencies**: External teams, systems, vendors, or approvals required - **Technical constraints**: Existing stack, legacy systems, migration requirements, must-not-break systems - **Definition of done**: What "success" looks like at the initiative level If team composition or timeline is missing, assume a 4–6 engineer team over one quarter and flag the assumption. ## Instructions ### Step 1: Clarify Scope and Non-Goals Before decomposing, establish boundaries: - **In scope**: 3–5 bullets stating exactly what this initiative will deliver - **Explicitly out of scope (non-goals)**: 3–5 bullets stating what this initiative will NOT do — this prevents scope creep and is the most-skipped step - **Success at the initiative level**: 2–3 measurable outcomes (e.g., "p99 latency under 200ms," "100% of traffic migrated," "zero downtime cutover") ### Step 2: Decompose into Phases Break the initiative into 3–6 sequential phases. Standard engineering initiative arc: - **Phase 0 — Foundation/Spike**: De-risking work, proof of concept, tooling, design doc, environment setup - **Phase 1 — Core Build**: The primary technical work that delivers the central capability - **Phase 2 — Integration/Migration**: Connecting to existing systems, data migration, backward compatibility - **Phase 3 — Rollout/Validation**: Progressive rollout, monitoring, load testing, cutover - **Phase 4 — Hardening/Cleanup**: Remove legacy paths, documentation, runbooks, on-call handoff Adjust phase count to the initiative. Each phase must produce something demonstrable or verifiable — no phase should end in an unmeasurable state. ### Step 3: Define Milestones Within Each Phase For each phase, define 2–4 milestones. Each milestone includes: - **Milestone name**: Concrete deliverable (e.g., "Read path served by new service," not "work on backend") - **Owner**: Assigned role or named person (single accountable owner per milestone — no shared accountability) - **Effort estimate**: T-shirt size (S/M/L/XL) with rough engineer-week range - **Dependencies**: Which milestones or external inputs must land first - **Success criteria**: A verifiable exit condition — a test that passes, a metric that's hit, a demo that works, a review that's signed off ### Step 4: Map Dependencies and Critical Path - List cross-milestone dependencies and identify the **critical path** — the longest chain of dependent work that determines minimum timeline - Flag any milestones blocked on **external teams or approvals** — these are the highest-risk items and need early kickoff - Identify **parallelizable work** — milestones that can run concurrently given the team size ### Step 5: Build the Risk Register Identify 4–6 top risks. For each: - **Risk**: What could go wrong (technical, dependency, resourcing, unknown-unknown) - **Likelihood / Impact**: Low / Medium / High for each - **Mitigation**: A concrete action to reduce or de-risk it - Prioritize risks that threaten the critical path or the initiative-level success criteria ### Step 6: Sequencing Recommendation Provide an opinionated ordering: - What to start in Week 1 (usually the highest-uncertainty spike + any external dependency kickoff) - What to explicitly defer - The single most important thing to get right early ## Output Format - **Structure**: Scope/non-goals block → phase-by-phase breakdown with milestone tables → dependency & critical path section → risk register table → sequencing recommendation - **Length**: 900–1,400 words - **Format**: Structured document with milestone tables (Milestone | Owner | Effort | Dependencies | Success Criteria) and a risk register table - **Sections**: Scope & Non-Goals → Phases & Milestones → Dependencies & Critical Path → Risk Register → Sequencing Recommendation - **Tone**: Engineering manager — pragmatic, direct, ownership-focused; assumes the reader will execute this plan ## Quality Checklist Before delivering output, verify: - [ ] Every milestone has exactly one accountable owner — no shared or blank owners - [ ] Every milestone has a verifiable success criterion (a test, metric, demo, or sign-off) — not "done when it works" - [ ] Non-goals section is present with at least 3 explicit exclusions - [ ] The critical path is named and external-team dependencies are flagged as high-risk - [ ] Risk register has 4–6 risks, each with likelihood, impact, and a concrete mitigation - [ ] Effort estimates are present on every milestone (T-shirt size + engineer-week range) ## Notes - The single highest-value output is usually the non-goals list and the success criteria — teams overrun because scope was never bounded and "done" was never defined - Front-load uncertainty: put spikes and external-dependency kickoffs in Phase 0, not Phase 3 - If the initiative can't be described in one sentence, it's probably two initiatives — flag this and suggest splitting - Prefer single accountable owners over "the team owns it"; shared accountability reliably becomes no accountability --- ## How to use this skill This file is a Claude Code skill in [Anthropic's standard format](https://docs.anthropic.com/en/docs/claude-code/skills) — markdown with YAML frontmatter at the top. **Installing in Claude Code:** - `~/.claude/skills//SKILL.md` — auto-loads in every session anywhere on your machine (recommended for skills you'll use across multiple projects) - `/.claude/skills//SKILL.md` — auto-loads only when working in that project (recommended for project-specific skills) Restart Claude Code or open a new session to register. **Using in Claude.ai, ChatGPT, Gemini, or other AI tools:** 1.
