Tim Bozarth, Microsoft CoreAI CVP, explains how AI is changing engineering productivity, why outcomes matter more than output, and what engineering leaders should measure instead.
The verification-over-generation point has numbers behind it now. Faros AI instrumented 22,000 developers across 4,000 teams and found task throughput per developer up 33.7% while median code review time rose 441.5%. LinearB, across 8.1 million pull requests, found AI-assisted PRs merge within 30 days only 32.7% of the time against 84.5% unassisted. That is the strongest argument I have seen for Bozarth's outcome metrics: activity metrics rise precisely when the new bottleneck is forming, so they read as success right up to the point the roadmap stops moving.
