Continual service improvement, defined in the ITIL continual service improvement volume, aims to align and realign IT services to changing business needs by identifying and implementing improvements to the IT services that support the business processes. It incorporates many of the same concepts articulated in the Deming Cycle of Plan-Do-Check-Act. The perspective of CSI on improvement is the business perspective of service quality, even though CSI aims to improve process effectiveness, efficiency, and cost-effectiveness of the IT processes through the whole lifecycle. To manage improvement, CSI should clearly define what should be controlled and measured. CSI needs to be treated just like any other service practice. There needs to be upfront planning, training and awareness, ongoing scheduling, roles created, ownership assigned, and activities identified to be successful. CSI must be planned and scheduled as a process with defined activities, inputs, outputs, roles, and reporting. Continual Service Improvement and Application Performance Management (APM) are two sides of the same coin. They both focus on improvement with APM tying together service design, service transition, and service operation which in turn helps raise the bar of operational excellence for IT.
The Information Technology Service Strategy
The ITIL Service Strategy (SS) provides guidance on clarification and prioritization of service-provider investments in services. More generally, Service Strategy focuses on helping IT organizations improve and develop over the long term. In both cases, Service Strategy relies largely upon a market-driven approach. Key topics covered include service value definition, business-case development, service assets, market analysis, and service provider types. List of covered processes.
The Information Technology Service Design
The Service Design (SD) provides good-practice guidance on the design of IT services, processes, and other aspects of the service management effort. Significantly, design within ITIL is understood to encompass all elements relevant to technology service delivery, rather than focusing solely on the design of the technology itself. As such, service design addresses how a planned service solution interacts with the larger business and technical environments, service management systems required to support the service, processes which interact with the service, technology, and architecture required to support the service, and the supply chain required to support the planned service. Within ITIL, design work for an IT service is aggregated into a single service design package (SDP). Service design packages, along with other information about services, are managed within the service catalog.
The Information Technology Service Operation
Service Operation (SO) aims to provide best practice for achieving the delivery of agreed levels of services both to end-users and the customers (where “customers” refer to those individuals who pay for the service and negotiate the SLAs). Service operation, as described in the ITIL Service Operation volume, is the part of the lifecycle where the services and value are actually directly delivered. Also the monitoring of problems and balance between service reliability and cost etc. are considered. The functions include technical management, application management, operations management, and service desk as well as, responsibilities for staff engaging in Service Operation.
The Information Technology Service transition
Service transition (ST), as described by the ITIL service transition volume, relates to the delivery of services required by a business into live/operational use, and often encompasses the “project” side of IT rather than business as usual (BAU). This area also covers topics such as managing changes to the BAU environment.
