AI IS MAKING ACTIVITY-BASED ENGINEERING METRICS OBSOLETE

Summary from the TLDR Dev newsletter

AI-generated code makes lines of code, commit counts, and raw pull request volume even weaker proxies for engineering value. The proposed replacement keeps delivery outcomes and adds team-level diagnostics such as review queue time, 14-day rework, validation failures, remediation deployments, and rework per unit of AI spend, while keeping them out of individual performance reviews.
