Service strategy establishes policies some principles that provide guidance for the whole service lifecycle. The service portfolio is defined in this lifecycle stage and new or changed services are chartered. During the service design stage of the lifecycle, everything needed to transition and operate the new or changed service is documented in a service design package.
This lifecycle stage also designs everything needed to create, transition and operate the services, including management information systems and tools, architectures, processes, measurement methods and metrics. The activities of the service transition and service operation stages of the lifecycle a defined during service design.
Service transition ensures that the requirements of the service strategy, which developed in service design are effectively realized in service operation our controlling the risks of failure and disruption.
The service operation stage of the service lifecycle carries out the activities and processes required to deliver the agreed services.
During this stage of the lifecycle, the value defined in the service strategy is realized. Continual Service Improvement (CSI) acts in tandem to the lifecycle stages.
Who processes, activities, roles, services and technology should be measured and subjected to continual improvement. The strength of the service lifecycle rests upon continual feedback throughout each stage of the lifecycle.
This feedback ensures that service optimization is managed from business perspective and measured in terms of the value the business drivers from services at any point in time during the service lifecycle.
At every point in the service lifecycle, the process of monitoring, assessment and feedback between each stage drives decisions about the need for minor course corrections or major service improvement initiatives.
Adopting appropriate technology to automate the processes and provide management with the information that supports the processes is also important for effective and efficient service management.
