I think number of features released to customers (not behind a feature flag or still being rolled out, but fully rolled out). And number of bug fixes (only those reported by customers).

Also just in general, customer satisfaction, acquisition, conversion, retention, etc.

Number of completed org-level roadmap items, org-level goals achievement rate, and so on.

I also think a good one would be seeing an increase in meeting estimation, like if project was estimated to take X days with Y devs, does the use of AI increased how often you met or beat those estimates in actual time/dev effort?

And you'd want to compare that against prior years, where no AI was used, within the same org, or try going 1 quarter without AI and another with and compare quarter to quarter.

Incredibly hard problem, but METR had a good method. They had people estimate how long a task would take (before knowing whether AI would be used), and then randomly assigned each task to “with AI” or “without AI.” When the data was in, they compared actual/estimate ratios of the two populations.

(Presumably, they used a t-test that only compared people against themselves.)

Interestingly, for that study (released in 2025), participants self-rated themselves as 20% more productive, but were measured as being 19% less productive.

Microsoft itself has a system for measuring this which outlines a few example metrics: https://queue.acm.org/detail.cfm?id=3819080

There was a nice talk about this by one of the author's at this year's BUILD conference: https://build.microsoft.com/en-US/sessions/BRK210

It'll probably take a really good product built by a profitable company evangelizing an AI workflow with reproducible examples dating back a few years.

We use a tool called Weave (I believe YC 25?) that analyzes PRs for "expert units of work" and shows lift from AI tools. My understanding is they have their own proprietary model that assesses the difficulty of each PR. I find the organization level view and pivots useful and aligned with intuitive expectations.

Engineering headcount.
