The document discusses how implementing ITIL best practices can help IT departments justify expenditures and reduce costs while improving services. It argues that ITIL allows organizations to "do more, for more, with less" by working smarter instead of just cutting costs. Specific areas where ITIL can generate savings are identified as vendor management, bandwidth management, asset management, increased end-user productivity, and increased labor efficiencies. The document provides examples of cost savings and avoidance that can be realized within short timeframes through ITIL processes like service level management, availability management, and capacity management.
