TL;DR

EY achieved 4-5x coding productivity gains by integrating AI agents with engineering standards and compliance frameworks. Success required organic cultural adoption and clear workload classification—agents excel at code review/defects/greenfield features while humans retain control over architecture. Developers organically gravitated to Factory over Lovable/Replit, proving adoption metrics matter more than top-down mandates.

Signal

• 4-5x productivity gains confirmed with full deployment; 15-60% efficiency gains measured in early adoption phase across different personas
• Factory (IDE-based agent platform) outcompeted competitors through organic developer adoption, not leadership decree; adoption "took off like wildfire" once moved to pilot
• Agents require "context universe" access (code repos, engineering standards, compliance frameworks); without it, output is generic and requires extensive rework

What They're NOT Telling You

Economic ROI and implementation costs are absent. Factory's specific technical advantages remain opaque—only that developers preferred it. No discussion of scalability to smaller organizations or precise attribution of gains (how much is agent capability vs. organizational/behavioral shifts?).
