Students' freedom to choose classes. When students know up front they have freedom to choose, they take greater responsibility for planning their own lives, thinking for themselves. Whenever people feel they have chosen to do whatever they are doing, they find greater enjoyment and intrinsic value in the activity. Interdisciplinary programs offer flexibility. Departments should have greater flexibility in chooses their program requirements without having to be subject to someone else's whims or territoriality.
Turf battles arise between different schools and departments.
Flexibility would include recognizing that other schools and departments are free to differ from your own in coursework, technology, and allocation of other resources. 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.
