Project Scheduling in the AI Era: Rebuilding Estimation, Velocity, and Sprint Planning From the Rubble
How AI coding agents broke estimation, velocity, and sprint planning, and what tech leads and EMs need to rebuild in their place. Covers why story points lost their meaning, how the bottleneck moved from implementation t
