API Governance Framework
What is an API? An Analogy for Non-Software Leaders
An API (Application Programming Interface) is that standardized order form, but for software.
In a modern company, different software systems handle different jobs: one manages customer data, another processes payments, and a third handles inventory. An API allows these systems to request services or data from each other in a predictable, efficient way. The mobile app team doesn't need to build its own payment processing system; it uses the "payment API" to request a transaction. This allows teams to work independently and assemble new products (features) from existing, reliable components.
Why Does API Governance Matter?
Without a central system for managing these "order forms," chaos ensues. This is the default state in most large organizations.
- Wasted Effort: Teams build the same component multiple times because they don't know an "order form" already exists. This is like building a new engine factory when a perfectly good one is sitting idle.
- Operational Failures: When the engine factory changes a bolt size without telling the assembly plant, the entire production line grinds to a halt. Similarly, when one software team changes its API without warning, other systems that depend on it break, causing outages.
- Security & Compliance Risks: Without knowing who is ordering what, you can't track who is accessing sensitive data (like customer information or financial records). This creates massive security holes and makes compliance audits nearly impossible.
API governance is the framework for managing these internal software supply chains. It’s not about bureaucracy; it's about creating a well-organized system where high-quality components are easily discoverable, reliable, and secure. It turns chaos into a strategic advantage.
This site presents a practical framework for governing internal APIs at scale, treating them as products rather than implementation details. It addresses the chronic problem of API chaos: duplicate work, security blind spots, compliance gaps, and slowing development velocity. The framework centers on three integrated platform components (Registry, Gateway, and Auditor) that provide discoverability, enforce access control, and measure quality, supported by organizational practices that balance developer autonomy with architectural consistency.
For executives, this represents a systematic approach to reducing the 30-40% of engineering capacity currently wasted on rebuilding capabilities that already exist, while mitigating operational, compliance, and competitive risks. For technical leaders, it provides detailed implementation guidance—from data models and lifecycle workflows to security controls and SDLC integration—that can be adopted incrementally without disrupting existing systems. Whether building from scratch or composing from existing tools, this framework offers a proven path from API chaos to governed, product-centric API ecosystems.
Quick Start
For Executives: Start with the Executive Summary to understand the business case and risk implications.
For Technical Leaders: Begin with the Governance Framework Overview to understand the complete system, then dive into Technical Design for implementation details.
For Implementation Teams: Review the framework documents, then choose your path: Build from Scratch for custom solutions or Build from Composition for integrated platform approach.

About
Over 15+ years, I’ve seen API governance fail at dozens of organizations. One came close to solving it — they had cobbled together a set of components that provided all these functions and actually worked at scale. It wasn’t perfect but it was close enough to be astonishing.
As a team lead managing a dozen APIs in their system, I experienced both what worked (visibility, discoverability, enforced patterns) and what didn’t (asset ownership, consumer management gaps, and difficult deprecation.) Bumping into their system daily, combined with seeing this problem everywhere for a decade, made the ideal solution suddenly obvious to me.
This framework expands upon such a system and addresses the gaps I experienced firsthand. It’s the system I wish I’d had as an API producer.
I’m looking to build this, either as a product or for an organization ready to solve API governance systematically.
