Architecture Governance for Multi-Team Organisation

All case studies

Challenge

A growing SaaS company with 8 engineering teams had no shared architecture standards. Each team made independent technology choices, leading to duplicated infrastructure, inconsistent APIs, and mounting technical debt that slowed feature delivery.

Approach

Established Architecture Decision Records (ADRs) as the standard for capturing cross-team decisions
Defined architecture guardrails with automated fitness tests enforced in CI/CD
Created a compliance matrix showing each service's adherence to shared standards
Ran monthly architecture reviews with team leads to evolve standards collaboratively

Results

60% reduction in cross-team integration issues

New services onboarded 3x faster with shared templates and guardrails

Architecture violations caught automatically in PRs before code review

Technical debt backlog reduced by 40% in the first quarter
