adr-roadmap

adr-roadmap

Purpose

Analyze a project's Architecture Decision Records (ADRs, Layer 5) and produce a phased implementation roadmap: dependency mapping, critical path, phase decomposition, timeline estimates, per-phase risk assessment, and a testing and technical-debt strategy. Engine-agnostic — works for any domain (web, mobile, data, ML, infrastructure, embedded).

Upstream: ADR. Downstream: feeds SPEC → TDD → IPLAN delivery sequencing.

When to Use

Use adr-roadmap when:

• A project has roughly five or more ADRs that need coordinated, phased rollout.
• You need visibility into architectural dependencies and the critical path.
• Stakeholders need a timeline, milestones, and an executive summary derived from ADR complexity.

Do not use it for a single ADR with a trivial implementation, for informational ADRs with no build work, when planning from requirements (use ../doc-brd/SKILL.md / ../doc-prd/SKILL.md / ../doc-ears/SKILL.md), or when you only need diagrams (use ../charts-flow/SKILL.md).

Behavior

1. Inventory ADRs — read every ADR-*.md, extract ID, title, status, complexity (1–5), effort, and dependencies; warn on missing complexity or broken dependency references; error if no ADRs are found.
2. Build the dependency graph — classify hard / soft / no dependencies, detect cycles (error), compute the critical path, and find clusters that can run in parallel.
3. Estimate effort — map complexity to base effort, sum across ADRs, apply a risk buffer (~20%), and flag high-risk ADRs (complexity 4–5 with many deps).
4. Form phases — apply the chosen phase model (poc-mvp-prod default, iterative, or waterfall), respecting dependencies, capping phase length (default 8 weeks), isolating risk, and ending phases on natural milestones. Adapt for greenfield, brownfield/migration (add rollback + dual-run), or refactoring (module-by-module) projects.
5. Build the timeline — derive phase durations from effort and team size, add inter-phase buffers, and produce a Gantt chart (via ../charts-flow/SKILL.md) with milestones.
6. Write the roadmap at {adr_dir}/ADR-00_IMPLEMENTATION-ROADMAP.md: Document Control, executive summary, per-phase sections (objectives, ADRs, architecture diagram, order, deliverables, success/exit criteria, risk), dependency matrix, technical-debt management, risk assessment, testing strategy, and traceability back to upstream (BRD–BDD) and downstream (SPEC/TDD/IPLAN) artifacts.

Constraints: use ADR decisions as-is (make no technology choices); map every ADR to exactly one phase; never exceed the phase cap; keep language objective; require rollback plans for production phases. Keep each document under 100k tokens.
