                Increasingly, IT Infrastructure Library (ITIL) practices are being adopted to improve the
                quality of IT services and reduce operating costs. Fujitsu provides the Systemwalker
                products that support IT service management according to ITIL best practices. This
                paper discusses the Systemwalker solutions that implement ITIL-based integrated IT
                service management, with an emphasis on ITIL service support.
