Having previously worked at a data team before the pandemic eon which raison'd etre was "saving cost", the reality is it didn't.

We used advanced statistical concept and vended models for other teams/services to consume, but the truth is either it was just really obvious cost solutions that they didn't bother, or it didn't really work all that well (stats model are, unfortunately, prone to many interpretations).

I've since moved on to feature based team where I feel like I'm more on the ground. And recently was able to get rid of lots of cost just by.. looking at them. I remain skeptical of the teams that base itself on statistical models to reduce cost.
