I came in my company as a team lead to a very disfunctional department, the developers were frustrated because of unclear requirements and the business side was upset because they could never get their deliverables despite "very clear" 100 page documentation specs and a "detailed" list of requirements.
They would email each other even though they were in the same office more to document everything and CYA than for communications.
On the dev side, I banned internal email for discussions. I told them that they must talk to people first if they are in the office and then send emails of documents, screen shots or whatever.
I also took it on as personal mission to never say "no" to any request and always talk to the person who was making the request - in person - see if we could come up with an acceptable compromise and tell them how it would affect their deliverable.
