Introduction
No matter how big or small, every organization needs a way to ensure its technical decisions align with business goals. This is where Architecture Governance comes in—a structured approach to making sure technology choices support the company’s overall strategy. But governance doesn’t look the same everywhere.
Let’s take a journey through three different companies—BigCo, MidCo, and StartX—to see how each handles architecture governance in its own unique way.
1. What Is Architecture Governance, Really?
Before diving into their stories, let’s clear up a couple of key terms:
- Architecture – More than just system design. It includes technical decisions, system structure, and non-functional requirements like performance and security. It also involves guiding principles such as “Cloud-first” or “API-driven.”
- Governance – Refers to the policies and processes that guide these decisions. It’s about finding the right balance—giving teams autonomy while ensuring overall alignment. Good governance isn’t about putting up roadblocks; it’s about facilitating smart decisions.
2. BigCo: Governance in a Large Enterprise
The Setting
BigCo is a global corporation with multiple product lines and a strong compliance culture. Given its size and complexity, governance needs to be formal and structured.
How It Works
- Review Board – Meets weekly or bi-weekly, consisting of the Chief Architect, security and compliance leads, and product heads.
- Decision Records – Every major decision is documented in enterprise tools like Confluence, ensuring traceability.
- Guiding Principles – Heavy focus on security, compliance, and scalability. Example: “Mission-critical systems must have multi-region redundancy.”
Roles
- Global Architects – Define company-wide standards and enforce compliance.
- Local Architects – Adapt those standards to specific product needs.
Challenges
- Bureaucracy can slow down innovation.
- Balancing global standards with local team flexibility.
Turning Point
A major system overhaul at BigCo faced significant delays due to misalignment between regional teams. To address this, BigCo restructured its Architecture Review Board (ARB) to serve as an advisory body rather than a strict approval gate. The ARB introduced pre-implementation reviews, where architects collaborated with engineering teams during the early design phase to identify risks and ensure compliance with global architecture principles.
3. MidCo: Governance in a Fast-Growing Company
The Setting
MidCo is expanding quickly, managing moderate complexity. Agility is crucial, but they also need some level of standardization.
How It Works
- Review Board – A hybrid model with a central oversight team and regional chapters that meet monthly or per project.
- Decision Records – Uses streamlined templates for documentation—keeps records lightweight but useful.
- Guiding Principles – Balance between cost-effectiveness and speed. Example: “Build APIs for future flexibility.”
Roles
- Small Global Team – Part-time architects who define overarching standards.
- Local Architects – Handle multiple responsibilities, ensuring practicality.
Challenges
- Scaling governance as the company grows.
- Keeping consistency without slowing down feature releases.
Turning Point
Multiple offices built conflicting CI/CD pipelines, creating chaos. To fix this, MidCo introduced an Architecture Decision Record (ADR) outlining a standardized deployment process. The ADR documented best practices, key decisions, and areas where teams could still maintain flexibility. The result? No more redundant efforts and a more streamlined development process.
4. StartX: Governance in a Startup
The Setting
StartX is a fast-moving startup where speed is everything. Everyone wears multiple hats, and agility is the top priority.
How It Works
- Review Board – Practically non-existent. Decisions happen in sprints or quick stand-ups, usually led by the CTO or lead developers.
- Decision Records – Lightweight Markdown files stored in GitHub—sometimes documented after key decisions are made.
- Guiding Principles – Lean and cost-conscious. Example: “Use open-source wherever possible.”
Roles
- No formal global team – The CTO and senior developers handle architecture responsibilities on the fly.
- Everyone contributes ideas in real time.
Challenges
- Risk of accumulating technical debt due to rapid pivots.
- Lack of formal governance can result in missed learning opportunities.
Turning Point
A rushed release led to major performance problems. To prevent this from happening again, StartX introduced lightweight Architecture Decision Records (ADRs)—a small step that made a big difference. It helped the team capture knowledge and avoid repeating mistakes, all without slowing down their agile processes.
5. Key Takeaways for Every Organization
No matter your company’s size, these lessons apply across the board:
- Clarity in Architecture – Architecture is more than just writing code—it’s about making well-informed decisions that align with business goals.
- Governance as Facilitation – Governance should empower teams, not act as a roadblock.
- Adapt to Growth – Lighter processes work well for startups, but mature businesses need more structured governance.
- Value of ADRs – Documenting decisions helps teams learn from the past and ensures transparency.
- Evolve Over Time – As a company grows, its guiding principles should be revisited and refined.
- Regular Check-Ins Matter – Whether it’s weekly, monthly, or per project, teams should sync up to ensure alignment.
- Foster a Collaborative Culture – Governance works best when it’s inclusive—not something imposed from the top.
Conclusion
BigCo, MidCo, and StartX all approach architecture governance differently, but the core principles remain the same—aligning technology decisions with business goals, managing risks, and fostering innovation.
By adapting governance structures to fit an organization’s size and stage of growth—and by documenting decisions effectively—companies can stay on track, avoid costly mistakes, and build resilient systems.
Above all, governance is a living process—it should evolve as your products, teams, and business landscape change.
