The way the buy in is measured is by conducting meeting with head departments and explain how students sucess is everyone responsability. I know our company conducts monthly call-a-thons for our grads and we recruit staff from other departments, and we work together and the goal is to reach out and engage to all of our graduate sometimes hearing a different voice or talking to another individual can make a graduate more confortable. Once the administration understands this concept then is easy for the rest of the staff to follow. At the end of the day we have a commitment and moral obligation to our graduates.
