Here's what our org is doing (still work in progress with ~3000 folks in development):
They gave a mix of AI tools to a few folks in different teams and ran pilots with various development teams across the org: front end, back end, domain heavy folks etc. It's been 6 months to 1 year so far, depending on the team. They have given these tools to carefully selected devs based on experience, past code check-ins etc. and urged them to focus on using the AI tools as much as they can and as frequently as they can, without worrying about how much work is getting done or how many tokens are being consumed. They allocated some ramp up time, assuming people will take time to understand how to use these tools. They setup internal forums where people could share their experience, tricks, tips etc.. They trusted these devs to be honest and work just as hard as they did without the AI tools. They now have some data to compare the results between folks who got the tools and those who did not.
Based on these finding, they are planning to roll out these AI tools to rest of the org with guidelines on which workflows best fit its use, best practices etc. Ofcourse this is an ever-evolving territory where nothing is constant. And AI itself is non-linear, it does not give the same results for the same constraints and prompts.
Fortunately, the org is privately held by one individual, so no investor pressure. No one was let go so far, but there has been a hiring freeze for quite some time now, with some fresher hiring for replacement.
