People are posting the same question all over the public channels: How is having Teams in addition to these other products saving us any money?
The answer is that it's not. First of all, Teams will replace pretty much everything eventually, but the reason Dan wants it in right this second is so they can effectively install spyware on every employee's computer.
Teams has insanely detailed tracking on keyboard/mouse usage, activity, time spent on computer, etc., and more importantly it rolls all that information up to people managers in nice, easy to consume dashboards.
Yes all of these things already exist in some form or fashion. But the information is fragmented, and managers don't currently have access to all of it. With Teams you get one centralized spyware platform that managers can easily access and consume.
I believe that the ultimate plan is to start culling remote employees by terminating for cause based on activity metrics to reduce headcount. Many other companies in the industry use teams to micro-manage and track remote employees, and many people are posting on forums like reddit about being terminated or written up for "7% decrease in activity levels".
USAA is trying to align itself with how the industry is controlling and targeting remote employees, and if I were one of them I would make sure I had a backup plan.
