Ginny,
Certainly, in order to provide a FREE service, your leadership needs to see the value of maintaining a relationship with your graduates.
I, personally, believe that our grads are living, breathing, walking advertisements for our institution. We pay LOTS of money for marketing. Why not tap into our own student's stories for this? If you are able to gather Alumni Success Stories via your alumni website/association and can put them on your websites, share them with employers, make success story posters to display at your campuses or even their workplaces, put together an Alumni Success Story Book, or even share them with your staff/instructors as a source of encouragement, there is power in a story!
To see an example - take a peak at several of the alumni success stories on the bottom of the home page of this website - www.alumni.pmi.edu
If you can get your financial decision-makers to see the value in this, they'll provide the budget.
June
