📥 Third-Party Component Onboarding and Offboarding

Intro: The real control is not only whether a component is approved today. It is whether the organization can explain who owns it, where it runs, what it can touch, and how to remove it quickly when trust changes.

What this page includes

  • onboarding workflow for third-party engineering components
  • minimal ownership and inventory data to capture
  • offboarding triggers and safe removal patterns
  • how to avoid abandoned trust in production paths

Minimum onboarding record

Capture at least:

  • component name and source;
  • owning team;
  • business reason;
  • environments where it runs;
  • secrets or trust relationships it receives;
  • whether it handles production artifacts or production configuration;
  • how to disable or replace it.

Offboarding triggers

Offboard or re-review when:

  • the maintainer goes silent or the project is archived;
  • the component requests broader access than before;
  • the business purpose disappears;
  • a major security incident affects the maintainer or dependency chain;
  • a safer internal alternative becomes available.
