Your outdated docs are costly: Why you should be writing tests for your docs

Internal Developer Platforms aim to create golden paths, reduce cognitive load, and standardize how teams build and operate software. But there is a blind spot: documentation.

READMEs, onboarding guides, and operational runbooks are often treated as static artifacts. Over time, they drift from reality, even as the platform itself evolves. The result is slower onboarding, brittle self-service workflows, and increased support burden on platform teams.

This talk explores documentation as an unverified surface within Internal Developer Platforms and introduces a practical approach to making it executable. It covers:
• Why documentation drift increases cognitive load and support tickets
• How to integrate executable documentation into platform pipelines
• How this approach strengthens golden paths and reduces onboarding time
• What changes in platform team workflows when documentation becomes testable
