Governance
Architecture Decisions
Architecture Decision Records documenting the key technology and strategy choices made during this engagement. Each decision captures context, rationale, and consequences.
Why this matters
Architecture decisions are the load-bearing commitments of the transformation. Recording them with context and rationale prevents re-litigation and enables informed challenge.
What this informs
Every downstream deliverable, the deprecation sequence, the vendor strategy, and the Phase 1 scope definition.
What remains unresolved
ADR-003 and ADR-006 are under review. ADR-004 requires steering committee input on China architecture track.
