Business Intelligence teams are diverse.
They range in skills sets.
From Chiefs to Seniors to Mid Level to Entry Level.
You have people who are highly technical.
To people just learning SQL.
You have people with great Business knowledge.
And you have people with Accounting expertise.
You have people with VM experience, Source Control, Databases, Networking, Hardware, Security, etc.
Some people enjoy the documetation side.
While others prefer new development and throw it over the wall to support.
I would say the intelligence of an Business Intelligence team is fairly high.
It's kind of a specialized segement of IT.
