DE - ES - ISO 20000 - ISO/IEC 20000 - ISO 20000 Requirements

ITIL provides guidance on what should be done in order to offer users adequate IT Services to support their business processes. ITIL qualifications are available for individuals but until recently there was no way for an IT organization to prove that it is working along the ITIL recommendations.

The ISO/IEC 20000:2011 standard (abbreviated to ISO 20000 in this wiki) was conceived to fill this gap. Initiated by the two organizations itSMF and BSI (British Standards Institution), it is modeled upon the principles of ITIL and allows IT organizations to have their IT Service Management certified.

In contrast to the ITIL books, ISO 20000 does not offer specific advice on how to design your processes. It is rather a set of requirements which must be met in order to qualify for ISO 20000 certification.

 

Central Requirements from ISO 20000

ISO 20000 promotes the “adoption of an integrated process approach to effectively deliver managed services to meet the business and customer requirements”.

ISO 20000 does not prescribe that its requirements must be met by following the ITIL recommendations, so there are many possible ways to achieve compliance. Introducing ITIL, however, is the most widely used approach for obtaining an ISO 20000 certificate.

It is also important to prove that IT processes are documented, actively managed, and continually improved.

 

The new Edition ISO/IEC 20000:2011

A new version of ISO/IEC 20000 Part 1: Service management system requirements (abbreviated to ISO/IEC 20000-1:2011) was published in April 2011.

The authors of the new version describe the main differences to the earlier edition (ISO/IEC 20000-1:2005) as follows:

• Closer alignment to both ISO 9001 and ISO/IEC 27001
• Clarification of existing definitions and addition of new definitions
• Introduction of the term "Service Management System" (SMS) and aligning the standard with the concept of a SMS
• Clarification of the requirements for the governance of processes operated by other parties
• Addition of requirements for the design and transition of new or changed services

 

How ITIL and ISO 20000 are related

The basic principles behind ITIL and ISO 20000 are very much in line (see also: "Alignment White Paper: ITIL V3 and ISO/IEC 20000", Jenny Dugmore & Sharon Taylor, March 2008). The key differences are:

• ITIL certifications are available for individuals only, whereas ISO 20000 is a certification scheme for organizations.
• ITIL is a rather detailed collection of best practices, while ISO 20000 is an international standard that sets out Service Management requirements for IT organizations.
• When organizations say they are compliant to ITIL, very often this statement is not verifiable; a certification according to the ISO 20000 standard means there has been an objective assessment.

Frequently, an ISO 20000 certification is sought after introducing ITIL, because it allows an IT organization to actually prove that it is a customer-oriented, efficient and effective supplier of IT services. A certification can thus be used for marketing purposes, or to gain access to customers and markets which require their service suppliers to be ISO 20000 certified.

 

ISO 20000 Sections and related ITIL Processes

ITIL was explicitly written to be aligned with ISO 20000, as the following table exemplifies: for every section in ISO/IEC 20000:2011, Part 1 (Mandatory Requirements) there are one or several related ITIL processes.

The following table summarizes in broad terms how the main ISO 20000 processes correspond to ITIL processes (ITIL 2011 main processes).

Note:

ITIL focuses on the life cycle of services, but offers less guidance on establishing and operating the Service Management System (SMS) itself. As a consequence, it is at times not straightforward to map the ITIL guidance and (especially) Section 4 and Section 5 of ISO 20000, but various ITIL processes together can typically be used to fulfill the requirements.
