How can teams reduce delays in the code review process?

By addressing unclear requirements early, using review milestones for new team members, and ensuring clear acceptance criteria and coding standards.

What are common process loopholes in code reviews and how can they be fixed?

Undefined processes, tool misconfigurations, and lack of feedback culture can create loopholes, which can be closed by clarifying policies and improving team communication.
