Committee Charter

The Information Technology Architecture Committee (ITAC) operated under the direction of the ITC and provided technical guidance to the ITC. ITAC consisted of highly skilled and knowledgeable IT staff. ITAC focused on setting technical standards, defining system, network, and information/data architectures and developing operational best practices. ITAC formed subcommittees to address specific technical issues or to address specific campus architectural designs and plans.
