Without going too into detail, my company is really, really big on estimates and predictable delivery timelines. An entire years worth of work is speced out, estimated, and scheduled by the end of October the previous year. It's a really terrible process, IMO, but it's the process so it is what it is.
Normally, most teams (mine included) are about 10% behind their plan by the end of Q1. This year my team is closer to 10% ahead despite the fact that we're down one engineer due to a small re-org at the end of last year. These projects were planned and estimated before AI was in heavy use and when, at best, most AI focused devs were still using it like smart auto-complete. Essentially, we estimated the projects before AI was heavily used and we're consistently beating those estimates by a good amount which is not how all previous years have gone.
The AI metrics dashboards didn't roll out until mid-March and, while I'm still seeing us beat our estimates from last year, we're not seeing any additional gains. Basically, all of Q1 we had AI and no dashboards and were beating 2025 estimates by X%. For Q2 we had dashboards and extra pressure to use AI and we're still seeing those X% gains, but no additional gains despite higher token usages.
We also have KPIs around completing a certain number of a certain type of Jira ticket that customers can file and we've seen a similar pattern of an sharp increase in tickets completed in Dec-Feb and then the new rate holds, but no additional increase after the company started pushing AI usage.
