The document discusses the evolution of service desks from their origins in the 1980s to support growing IT use, to a proposed new model of "Service Desk 2.0". It notes that people now expect self-service options and want to solve problems themselves using consumer tools. A Service Desk 2.0 would have new goals around customer value rather than activities, involve many support sources beyond the official desk, and make better use of social media and community support. It suggests moving away from rigid ITIL processes to adaptive case management that uses multiple information sources. Examples are given of companies that saw cost reductions and increased customer satisfaction by embracing these new support models.
