TL;DR · WeSearch summary

AI tools have significantly increased code generation speed, leading to higher pull request (PR) volume and larger PR sizes, but code review times have surged even more, creating a bottleneck in software delivery. Senior engineers now spend more time reviewing AI-generated code due to increased cognitive demands, despite faster initial development. The key to improvement lies in risk-based triage, better visibility into PR queues, and tools that streamline the review process.

Key facts

▪Median time in PR review has increased by 441% and average review time by nearly 200% despite faster code generation.
▪31% more PRs are merging without review because reviewers cannot keep up with the volume of AI-generated code.
▪Senior engineers spend 4.3 minutes reviewing AI-generated code compared to 1.2 minutes for human-written code due to higher cognitive load.
▪Risk-based triage and unified PR visibility tools like Code Board help teams prioritize review efforts based on PR impact and risk.
▪High-performing teams review PRs within 4 hours, while averages above 24 hours indicate a critical delivery bottleneck.
