Page 6September 2004 © Copyright Massachusetts Institute of Technology 2004, All Rights Reserved Future State Context SAP will continue to be the primary ERP system The MIT Data Warehouse will be the central repository for administrative data that is of interest to more than one DLC. The MIT community will continue to be global, 24x7 and evolving There will be increased integration between MIT and other universities The MIT environment is heterogeneous The MIT network will evolve to support needs of the enterprise We may have many research networks We will have an IPv6 network and we will need differentiated services to better support user needs
