The life cycle of ITSS mainly includes five stages. The first stage is the planning and design stage, which is mainly responsible for the overall planning and design of IT services.
The second stage is the deployment and implementation stage, that is, according to the planning and design of the first stage, the corresponding management system is established, the components of IT services are rationally configured, and service solutions are put forward.
The third stage is the service operation stage, that is, through all-round process management, the continuity of business is guaranteed, and the operation of customers is combined with the operation of IT services.
The fourth stage is the stage of continuous improvement, that is, regular inspection and evaluation, timely detection of problems in the process of IT services, timely improvement, in order to improve the quality of IT services.
The fifth stage is the supervision and management stage, that is, according to the relevant quality evaluation standards of ITSS, the related services are evaluated, the service quality in the process of IT service is evaluated, the process and result of service delivery are supervised, and the evaluation is made.
Extended data:
principle
ITSS is a standard library, which has realized a series of standards from basic evaluation standards and management control standards to consulting, integrated implementation and operation and maintenance around all aspects of information technology services, and realized three-dimensional system integration from basic, governance, management and industry applications. The core elements of ITSS capabilities have been fully and powerfully expressed and applied in information technology services at all levels.
That is, the capacity system construction runs through all parts of information technology services, realizing the systematic operation of information technology services, and its overall content is deeply integrated and integrated, so that enterprises can effectively unify and integrate when using different parts of standards. In the principle of construction, we should follow the principles of centralized planning, overall arrangement, management support, full participation and continuous improvement.
