Supporting position

Measure what lands, not what is typed.

Under abundant generation, volume metrics (lines of code, "percent faster") are misleading. The signals that matter are acceptance rate, rework and stability.

Conventional wisdom

More output means more productivity.

Our position

Measure what reaches production, not what reaches Git.

Why we believe it

Effort has decoupled from value. The signals that matter are acceptance, rework and stability — not volume or perceived speed.

What we’ve observed

  1. 01A randomised trial found experienced developers ~19% slower with AI while feeling faster.
