Summary

Google Cloud describes ADRs as a way to explain why infrastructure or application teams made specific design choices. The guidance emphasizes keeping decision history close to the code and using ADRs to preserve context as business needs, technical requirements, and available solutions change.

Relevant Findings

ADRs are useful when future teams need the background behind a specific architecture choice.
Decision history helps explain architecture evolution over time.
ADRs should connect the decision to associated code, infrastructure, or system design.
Lightweight records can streamline technical decision-making when they are consistently created and maintained.

HELIX Usage

This resource informs the Architecture Decision Record artifact. HELIX uses it to emphasize traceability from a decision to architecture, designs, code, and future reconsideration triggers.

Authority Boundary

This resource is cloud-focused and does not require Google Cloud. HELIX ADRs can apply to any architecture-significant decision across application, infrastructure, data, security, or operations.
