Breaking the PR Review Bottleneck
summary
Claims: pull request review is the dominant delivery bottleneck and fixing processes before adding AI speeds delivery. Concrete wins include queue reduced from dozens to single digits and shipping some features in under a week after changes. Measured metrics are time to first review (within an hour → merge within a day), median time to merge, and change failure rate. Practical tools and patterns are Ruff and MyPy, GitHub/GitLab merge queues, code owners, a PR Wrangler with a 24‑hour SLA, Kanban and auto‑linting, plus cautious use of Codex Copilot Cursor Cloud Code.
