1. AI as a Governance Layer Across the Full Software Lifecycle

InfoQ (Leela Kumili). Uber, DoorDash, and Cloudflare are each pushing AI upstream from code generation into requirements validation and structured review, treating it as a governance checkpoint rather than a productivity shortcut. Uber’s first-pass PRD system evaluates product requirement documents for clarity, completeness, and execution risks before engineering teams ever see them, with engineers noting the primary value is surfacing missing dependencies and inconsistencies early. DoorDash optimized their AI code reviewer around fewer but higher-quality comments to drive real behavior change, while Cloudflare found that specialized agents scoped to security, performance, and correctness individually outperform a single general-purpose reviewer — a practical argument for decomposing review workloads into tightly bounded agents.
