AFAIK nobody was collecting analytics. The one team I was working on had put out a goal of "30% more efficient" using AI tools. Its about as subject as you can get. We never got around to what exactly that meant before everything got shut down.

Myself and several other devs were laughing about the whole thing. The company was so amped about what AI could do they never even bothered collecting any analytics that would affirm or deny any of this had a positive impact. Even some of my team members were talking about the placebo effect AI has had on a lot of C-Suite folks.
