Architecture Decisions

Architecture Decision Records documenting key technology choices, their context, and consequences. Living documents — revisited as context changes.

Why this matters

These decisions define the architecture constraints and freedoms for the transformation. Unresolved decisions block downstream deliverables and Phase 1 scoping.

What this informs

Every deliverable, the deprecation strategy, vendor selection criteria, and the Phase 1 investment case.

What remains unresolved

ADR-003 (Composable DXP) and ADR-006 (SAP retention) require steering committee input. ADR-004 (China track) awaiting annex completion.

Each decision follows a structured evaluation against the architecture principles. Decisions progress through a defined lifecycle from draft to confirmed.

Draft

Initial observation or option identified. Context documented. Not yet evaluated.

Under Review

Evaluation in progress. Rationale being developed. Stakeholder input being gathered.

Decision Needed

Evaluation complete. Recommendation formed. Awaiting formal decision from steering committee.

Confirmed

Decision made and documented. Consequences accepted. Implementation can proceed.

Decision Layer

Decision Authority

Technical decisions confirmed by architecture lead. Strategic decisions require steering committee approval.

Dependencies

Open decisions block DEL-006, DEL-009, and Phase 1 scope. Enterprise deviations require architecture board sign-off.

Next Actions

Schedule steering committee for ADR-003 and ADR-004. Request SAP roadmap for ADR-006 resolution.

Confidence

Medium — three decisions confirmed, three require steering input. Review cadence is bi-weekly during Phase 0.
