Decision Record​

Decision: Implement comprehensive code review workflow processes with five workflow types, tool integration, and metrics tracking.

Rationale:

  • Provides systematic approach to code reviews
  • Supports different change types and scenarios
  • Integrates with existing tools and workflows
  • Enables efficient, thorough reviews
  • Ensures consistent review quality

Alternatives Considered:

  • Single workflow for all changes (too rigid)
  • Ad-hoc reviews (inconsistent)
  • Tool-only reviews (lacks human judgment)
  • Manual-only workflows (not scalable)

Consequences:

  • Requires initial setup and documentation
  • Workflows may need refinement based on experience
  • Provides foundation for systematic reviews
  • Enables efficient, high-quality code reviews
