What is Stack Overflow for Teams used for?

According to me; Stackoverflow for Teams can be used in several way. One way is to bind everyone in the office together with one common knowledge base. People have lots of questions that are specific to the office itself. This is like a wiki, in many respects The other way is to start a Stackoverflow for Teams for a core group of users -- say you are launching a product and you want to stay close and provide support to your first set of clients. This would be that exclusive system for that first lot -- the very early adopters of what you are offering.

Majorly it can be used for internalised Q& A platform for cretaing a question bank and a knowledge share space.
