ISO 20000-1:2018 - IT Service Management System (ITSMS)

IT is essential to delivering today’s business. However, concerns are increasingly being raised about IT services, internal and outsourced, not aligning with the needs of businesses and customers. A recognized solution to this problem is to use an IT Service Management System (ITSMS) based on ISO/IEC 20000, the international standard for IT service management. Certification to this standard enables you to independently demonstrate to your customers that you meet best practice. ISO/IEC 20000 is based on and replaces BS 15000, the internationally recognized British Standard.

ISO/IEC 20000 is the first international standard for service management. It was developed in 2005 by ISO/IEC JTC1/SC7 and revised in 2011 and 2018. It was originally based on the earlier BS 15000 that was developed by BSI Group.

ISO/IEC 20000, like its BS 15000 predecessor, was originally developed to reflect best practice guidance contained within the ITIL (Information Technology Infrastructure Library) framework (reference needed), although it equally supports other IT service management frameworks and approaches including Microsoft Operations Framework and components of ISACA’s COBIT framework.

The standard was first published in December 2005. In June 2011, the ISO/IEC 20000-1:2005 was updated to ISO/IEC 20000-1:2011. In February 2012, ISO/IEC 20000-2:2005 was updated to ISO/IEC 20000-2:2012.

ISO 20000-1 has now been revised by ISO/IEC JTC 1/SC 40 IT Service Management and IT Governance. The revision has been released in July 2018. From that point certified entities enter a three year transition period to update to the new version of ISO 20000-1.

Formally: ISO/IEC 20000-1:2018 (‘part 1’) specifies requirements for “establishing, implementing, maintaining and continually improving a service management system (SMS). An SMS supports the management of the service lifecycle, including the planning, design, transition, delivery and improvement of services, which meet agreed requirements and deliver value for customers, users and the organization delivering the services.” The 2018 version (ISO/IEC 20000-1:2018) comprises ten sections, following the high-level structure from Annex SL of the Consolidated ISO/IEC Directives,

Scope
Normative references
Terms and definitions
Context of the organization

  • Part One is the specification for service management which covers the IT service management. It is this part which you can be audited against and it sets out minimum requirements that must be achieved in order to gain certification.
  • Part Two is the code of practice for service management, which describes the best practices for service management processes within the scope of the specification.
  • ISO/IEC 20000 Cerification is applicable to any organization, large or small, in any sector or part of the world which relies on IT services. The standard is particularly suitable for internal IT service providers, such as IT departments, and external IT service providers, such as IT outsourcing organizations.
  • The standard is already making a positive impact in some of the leading IT-dependent sectors, such as the business process outsourcing, telecommunications, finance and public sectors
  • IT service providers become more responsive to services which are business led rather than technology driven
  • Reduction in incidents and improved incident management
  • Gives you the ability to select and manage external service providers more effectively
  • More opportunities to improve the efficiency, reliability and consistency of IT services impacting costs and service
  • Enhanced customer satisfaction that improves client retention
  • The certification process can reduce the amount of supplier audits, thereby reducing costs
  • ISO 20000 is fully compatible with the ITIL (IT Infrastructure Library) framework of best practice guidance for ITSM processes
