What did the Figma Make trial measure?

Fifty product designers and fifty product managers, recruited and moderated by MeasuringU, did three tasks on a social media app with or without Figma Make: convert a screen to dark mode, add a Help & Support item to a settings menu, and prototype a comment flyout. Each task came with a picture of the finished design. AI cut time about 20% overall, 35% for PMs and 17% for designers, and by Nielsen's arithmetic cut the gap between the roles from 26 minutes to 8. The trial measured reproducing a known design, not deciding what the design should be.

What does design own if not the review?

Six of the thirteen rows on the ownership map: what the product will not do, the constraint set for a surface, the acceptable range of generated output, the quality rubric and its dimensions, when output is good enough to ship, and the wrong path. Row five is a call design makes, and the rubric in row four is what makes that call run without the designer in the room.

How big is the rubric?

One page, three to five criteria, at least 20 test cases, the same sizes I use instead of a PRD. Grade thirty outputs before writing a criterion so the dimensions come from real failures, and score binary per dimension wherever you can, because a 1-to-5 scale hides disagreement inside the 3.

Should Designers Be the Quality Gate for PM Prototypes?

Should designers be the quality gate for PM prototypes?

THE SHORT ANSWER

No. A person as a gate caps the product at the number of things one person can look at, and Figma's randomized trial of Figma Make, as Jakob Nielsen reports it on October 19, 2026, just raised the volume: PMs got 35% faster and roughly 70% of the gap to designers closed. The gate should be the rubric design writes. The ownership map in my design handbook gives design six of thirteen rows, none of them reviewing the PM's prototype. A PM's prototype arrives scored against a one-page rubric with three to five criteria and at least 20 test cases, and the designer's time goes to the rows no rubric holds yet.

A person as a gate was already the failure mode before the trial. What Design Owns Now(coming Nov 11) names it: a design leader who is the only quality gate in the company caps the product at the number of things one person can look at. Nielsen's trial numbers describe the queue getting longer, and his advice routes it through the one resource that did not get faster.

The replacement is not fewer prototypes from PMs. It is a rubric per surface, written by design, applied before the prototype reaches anyone. The argument, the six rows, and why the trial could not test judgment because it handed out the finished picture are in Figma's Trial Closed 70% of the PM Gap. The Gate Is the Rubric, Not the Designer.. The rubric sizes come from Kill the PRD. The Prototype Is the Spec. and the grading method from How I Build Eval Rubrics.
