An Architecture Review Board (ARB) is a governance body that evaluates and approves significant technical decisions — new technologies, architecture changes, platform migrations, and build-vs-buy decisions.

ARB responsibilities: - Review and approve major architecture decisions - Maintain architecture decision records (ADRs) - Ensure consistency across teams and services - Evaluate technical risk of proposed changes - Set and maintain technology standards

Anti-patterns: An ARB that moves too slowly becomes a bottleneck. An ARB that rubber-stamps everything provides no value. The best ARBs are lightweight, async-first, and focus only on high-impact decisions.

Architecture Decision Records (ADRs): Written documents that capture the context, decision, and rationale for significant architecture choices. ADRs are the institutional memory that prevents repeated debates.

💡 Why It Matters

Without architecture governance, teams make inconsistent technology decisions that create architectural debt. With too much governance, teams can't move fast. The balance is critical.

🚫 Common Mistakes to Avoid

1
Implementing Architecture Review Board without executive sponsorship
⚠️ Consequence: Initiatives stall when competing with feature work for resources.
✅ Fix: Secure VP+ sponsor who can protect budget and prioritize the initiative.
2
Treating Architecture Review Board as a one-time project instead of ongoing practice
⚠️ Consequence: Initial improvements erode within 2-3 quarters without sustained effort.
✅ Fix: Embed into regular rituals: quarterly reviews, team OKRs, and reporting cadence.
3
Not measuring Architecture Review Board baseline before starting
⚠️ Consequence: Cannot demonstrate improvement. ROI narrative impossible to build.
✅ Fix: Spend the first 2 weeks establishing baseline measurements before any changes.
4
Copying another company's Architecture Review Board approach without adaptation
⚠️ Consequence: Context mismatch leads to poor results and wasted effort.
✅ Fix: Use frameworks as starting points. Adapt to your team size, stage, and culture.
