This Standard adopts ISO/IEC 20000 3:2019 which provides guidance on the scope definition and applicability to the requirements specified in AS/NZS ISO/IEC 20000.1. This Standard can assist in establishing whether AS/NZS ISO/IEC 20000.1 is applicable to an organization’s circumstances. It illustrates how the scope of an SMS can be defined, irrespective of whether the organization has experience of defining the scope of other management systems. The guidance in this Standard can assist an organization in planning and preparing for a conformity assessment against AS/NZS ISO/IEC 20000.1. Annex A contains examples of possible scope statements for an SMS. The examples given use a series of scenarios for organizations ranging from very simple to complex service supply chains. This Standard can be used by personnel responsible for planning the implementation of an SMS, as well as assessors and consultants. It supplements the guidance on the application of an SMS given in AS/NZS ISO/IEC 20000.2. Requirements for bodies providing audit and certification of an SMS can be found in AS/NZS ISO/IEC 20000.6 which recommends the use of this Standard.
