Best Practices Summary

Organization Base

Keep @acme/base focused on universal policies that apply everywhere.

Security Integration

Always @use @acme/security in team bases, never skip security.

Version Management

Tag registry releases and pin versions in production projects.

Breaking Changes

Major version bumps require migration guides and team notification.

Review Process

All registry changes need appropriate CODEOWNER approval.

Rollout Timeline

Phase Duration Goals
Pilot 4 weeks 3 teams, feedback collection
Team Rollout 8 weeks All teams onboarded
Mandatory Ongoing Required for new projects
Full Migration 6 months All existing projects migrated
