This document provides guidance on the application of a service management system (SMS) based on ISO/IEC 20000-1. It provides examples and recommendations to enable organizations to interpret and apply ISO/IEC 20000-1, including references to other parts of ISO/IEC 20000 and other relevant standards.
Figure 1 illustrates an SMS with the clause content of ISO/IEC 20000-1. It does not represent a structural hierarchy, sequence, or authority levels.
The structure of clauses is intended to provide a coherent presentation of requirements, rather than a model for documenting an organization’s policies, objectives, and processes. Each organization can choose how to combine the requirements into processes. The relationship between each organization and its customers, users, and other interested parties influences how the processes are implemented. However, an SMS as designed by an organization cannot exclude any of the requirements specified in ISO/IEC 20000-1.
The term ‘service’ as used in this document refers to the services in the scope of the SMS. The term ‘organization’ as used in this document refers to the organization in the scope of the SMS. The organization in the scope of the SMS can be part of a larger organization, for example an IT department of a large corporation. The organization manages and delivers services to customers and can also be referred to as a service provider. Any use of the terms ‘service’ or ’organization’ with a different intent is distinguished clearly in this document. The term ‘delivered’, as used in this document, can be interpreted as all of the service lifecycle activities that are performed in addition to daily operational activities. Service lifecycle activities include planning, design, transition, delivery, and improvement.
