THE FIVE MAJOR ASPECTS OF SERVICE DESIGN
ITIL formally recognises five separate aspects of service design that together
describe the scope of this part of the service lifecycle:
• The introduction of new or changed services through the accurate identification of business requirements and the agreed definition of service requirements.
• The service management systems and tools such as the service portfolio,
ensuring mutual consistency with other services and appropriate tools support.
• The capability of technology architectures and management systems to operate and maintain new services.
• The capability of all processes, not just those in service design, to operate and maintain new and changed services.
• Designing in the appropriate measurement methods and metrics necessary for performance analysis of services, improved decision-making and continual improvement.
