To create an Architecture Decision Record for a data engineering platform, you define the target architecture, decision context, goals, and major trade-offs, validating storage, compute, and security choices against business constraints before physical implementation.

Validating data architecture readiness involves generating an evidence-backed support plan and evidence pack to ensure downstream ingestion, storage layers, transformations, and orchestration do not depend on undocumented or unjustified architectural choices.

An evidence-backed ADR helps establish data governance and security posture by explicitly capturing architecture decisions, ensuring security, privacy, governance, and cost trade-offs are validated and documented prior to physical schema design and data ingestion.

Yes, you need upstream artifacts and Phase 06 conceptual modeling outputs to establish a global data engineering architecture, ensuring the Phase 06 to 07 handoff readiness is met before producing the architecture decision record.

No, you cannot design physical schemas or code during the data architecture decision phase; the process focuses solely on defining storage, compute, and integration layers, producing an ADR, support plan, and handoff outputs for subsequent implementation.

You should not start data ingestion before documenting architecture trade-offs because doing so risks downstream phases depending on unjustified choices, potentially misaligning storage, orchestration, and governance with business goals, domain constraints, and cost realities.
