Lightweight ARB Process From the First Principles
Principles
Enablement Over Gatekeeping:
ARB acts as a supportive advisor rather than an approval bottleneck, empowering teams to confidently make decisions.Agility Through Asynchronous Reviews:
Reviews are conducted asynchronously (design docs, PRs, ADRs), enabling teams to move swiftly before the review.Address Non-Functional Early:
Proactively addresses security, scalability, compliance, and tech debt throughout development, rather than as post-development audits.Continuous Evolution and history of Decisions:
Architecture is dynamic; ARB supports incremental improvements and continuous adjustments. These decisions are captured in Architecture Decision Records (ADRs) for future reference.Collaboration Over Control:
ARB fosters cross-functional collaboration, offering insights from security, operations, compliance, and more, while decisions remain with product teams.Contributing to Product Features:
ARB contributes insights to functional requirements, user experience as well as architectural recommendations that directly enhancing product features and customer value.Maximize Reuse and Shared Services:
ARB proactively encourages teams to leverage shared and common business services, reducing redundancy and promoting enterprise-wide consistency.
Actionable Steps for ARB Integration
| Action | Description | Example |
|---|---|---|
| Asynchronous Design Reviews | Teams submit standardized design documents asynchronously; ARB provides feedback within a defined timeframe. | Reviews with ARB feedback provided asynchronously and via comments. |
| Self-Service Templates and Checklists | Equip teams with templates and compliance checklists, enabling autonomous baseline quality verification. | A standardized "ARB" checklist covering security, scalability, logging, and compliance. |
| Cross-Functional Liaisons | ARB assigns architecture champions or domain experts who proactively engage with product teams. | A Data architect advises a team implementing critical database design choices. |
| Continuous Learning & Iteration | Maintain Architecture Decision Records (ADRs) and tech debt registers to continuously track, revisit, and evolve architecture decisions. | Team revisits its database choice documented in an ADR after scaling issues in production. |
| Product Feature Alignment & Shared Services | ARB proactively discovers andidentifies opportunities for alignment and reuse of common core & business services across teams. | Central authentication services reused by multiple teams rather than separate implementations. |
| ARB Contribution to Product Roadmap | ARB collaborates with product teams to translate architectural improvements into customer-facing product features. | Recommendations for enhanced observability tools for better analytics. |
| AI Chatbot for Historical ADR Insights (new) | Integrate an AI-powered chatbot to facilitate insights from historical ADRs, enabling quick access to past architecture decisions. | Developers ask chatbot, "Have we previously decided on Redis vs. Memcached for caching?" and receive immediate context from past ADRs. |
