A formal enterprise data group should probably

- be a clone/repo for disparate databases so you don't need to figure out access/security/location or impact production systems

- an interface to management types that aren't technical or don't have tech people to do these things

- should provide a "librarian" knowledge of the enterprise's data and data sources

- should have knowledge on how to analyze data using different tools

- be able to schedule movements/reports and manage that

If you don't need any of that, then ... yeah, don't use it. But those sets of requirements should be useful to anything that deems itself an "enterprise".
