## Summary

James Shore argues that delivery speed is only a component of software productivity, which he defines as value produced divided by money spent. He says estimates and story counts cannot show whether AI makes teams faster, so teams should be compared to themselves using randomized, interleaved with-AI and without-AI tasks. This is part 2 of his series, published on O'Reilly Radar.
