Don't dictate that everyone fit the same mold. Recognize what other departments have. Interact with other departments. Allow different departments the flexibility to offer their own courses even if someone outside the department might think they seem redundant. For example, several departments offer their statistics courses because they differ in the kinds of statistics they each or simply the kinds of statistics they emphasize.
Interdepartmental communication is needed.
Better advising is essential. Encourage the writing minor. Almost everything we're talking about takes money. Administrators need freedom so they can have more time to raise funds, etc. Faculty need to get more involved in fundraising.
