The Open Group is a global consortium that enables the achievement of business objectives through IT standards. With more than 450 member organizations, The Open Group has a diverse membership that spans all sectors of the IT community – customers, systems and solutions suppliers, tool vendors, integrators, and consultants, as well as academics and researchers – to:
• Capture, understand, and address current and emerging requirements, and establish policies and share best practices
• Facilitate interoperability, develop consensus, and evolve and integrate specifications and open source technologies
• Offer a comprehensive set of services to enhance the operational efficiency of consortia
• Operate the industry’s premier certification service
Further information on The Open Group is available at www.opengroup.org.
The Open Group publishes a wide range of technical documentation, most of which is focused on development of Open Group Standards and Guides, but which also includes white papers, technical studies, certification and testing documentation, and business titles. Full details and a catalog are available at www.opengroup.org/bookstore.
Readers should note that updates – in the form of Corrigenda – may apply to any publication. This information is published at www.opengroup.org/corrigenda.
The IT4IT Forum, a Forum of The Open Group, was created when its predecessor, the IT4IT Consortium, transferred its activities to The Open Group. The IT4IT Consortium came into being in 2011 as a practitioner-driven initiative. The Consortium was comprised of IT professionals from multiple industry segments and several IT vendors who agreed to share their experiences for the purpose of developing and publishing future-safe prescriptive guidance for implementing end-to-end an IT4IT architecture with full insight. Past and present members include Enterprise Architects and IT department leaders or industry consultants from: Accenture, Achmea, AT&T, HP IT, ING Bank, Munich RE, PwC, Royal Dutch Shell, and University of South Florida.
The Consortium formed a strategy board that spent thousands of hours sharing their insights and analyzing their experiences to develop a future-safe IT operating model. This model includes a prescriptive architecture for implementing the IT Value Chain to optimize the efficiency and effectiveness of IT. The strategy board is backed by an executive board sponsor from each member company.
“Cloud services and multi-provider outsourcing are adding new degrees of complexity to IT service management. The Consortium will use its real-life, cross-industry expertise to define a new operating model for IT.”
Dr. Dirk Heiss, Global Infrastructure Services Officer, Munich RE
The Open Group IT4IT™ Reference Architecture refers to the capability or capabilities required to manage the business of IT, covering IT end-to-end from plan, through build and operate. It assumes the principle that the business of running IT is industry-agnostic and that IT leaders share the same problems and opportunities in managing the service lifecycle effectively. At the core, these problems are rooted in IT structure, competencies, and capabilities and the missing link has been the lack of an IT operating model. The IT4IT Reference Architecture proposes that it is possible to establish an IT operating model standard mapped to the existing IT landscape yet flexible enough to support the volatility inherent in the IT industry and accommodate changing IT paradigms (composite apps, agile development, mobile technology, multi-sourcing, etc.).
The IT Value Chain and IT4IT Reference Architecture represent the IT service lifecycle XE "IT service lifecycle" in a new and powerful way, providing the missing link between industry standard best practice guides and the technology you need to select and execute those processes. The IT Value Chain and IT4IT Reference Architecture are a new foundation on which to base your IT4IT operating model and provide a welcome blueprint for the CIO to accelerate IT’s transition to becoming a service broker to the business.
This document is The Open Group IT4IT Reference Architecture, Version 2.0, an Open Group Standard. It has been developed and approved by The Open Group.
This document is structured as follows:
Chapter 1 (Introduction) introduces this document and the purpose of the IT4IT work.
Chapter 2 (Definitions) lists important definitions needed in order to read the document.
Chapter 3 (Overview) is an introduction for executives and others introducing the IT Value Chain and IT4IT Reference Architecture concepts.
Chapter 4 (IT4IT Core) defines the structure of the IT4IT standard as well as the process and document structure used by the IT4IT standard.
Chapter 5 (Strategy to Portfolio (S2P) Value Stream) explains the S2P Value Stream in detail.
Chapter 6 (Requirement to Deploy (R2D) Value Stream) explains the R2D Value Stream in detail.
Chapter 7 (Request to Fulfill (R2F) Value Stream) explains the R2F Value Stream in detail.
Chapter 8 (Detect to Correct (D2C) Value Stream) explains the D2C Value Stream in detail.
Appendix A (Rationale (Informative)) contains background information on the standard.
It is recommended that the reader start by familiarizing themselves with Chapter 3 (Overview) which introduces the concepts of the IT Value Chain. This should then be followed by the IT4IT Core (Chapter 4), and the four IT Value Streams. These are:
Strategy to Portfolio (S2P) Value Stream (Chapter 5)
Requirement to Deploy (R2D) Value Stream (Chapter 6)
Request to Fulfill (R2F) Value Stream (Chapter 7)
Detect to Correct (D2C) Value Stream (Chapter 8)
Figure 1 is a graphical representation of the data objects associated with the IT4IT Reference Architecture. The architecture is comprised of a set of normative documents[1] and a formal model described using the ArchiMate® XE "ArchiMate language" modeling language and UML XE "UML" . These define “what” the architecture is. The normative documentation includes:
IT4IT Reference Architecture Overview
IT4IT Value Stream Overview
IT4IT Reference Architecture diagrams
IT4IT meta-model diagram
Glossary
The Reference Architecture diagrams, in ArchiMate notation, will be provided as a set of web pages, and also as a downloadable zip file of those pages. When available, they will be found at: https://collaboration.opengroup.org/data/IT4IT/RA_2.0.
A set of guidance documents is being developed to accompany the architecture, intended to describe “how” to apply the architecture in practice. Planned guidance documents include:
Multi-Supplier Management White Paper
Definition of IT Service White Paper
Service Model Management White Paper
Scenario White Papers (see Section 4.2.6.1)
Figure 1: Documentation Structure of the IT4IT Reference Architecture
Documents/artifacts that fall into these two categories are governed by The Open Group Standards Process. In addition, The Open Group will maintain a set of White Papers that complement the architecture and elaborate on its applicability and use in various settings.
Most IT management standards fall into one of two categories: process and/or method-focused technology and/or implementations-centric. There are no standards that prescribe both the operating model and automation guidelines for running the IT function. Therefore, the IT4IT Reference Architecture fills this gap and as such complements a number of existing standards and best practices such as:
ISO/IEC 19770:2012: Information Technology – Software Asset Management
ISO/IEC 20000:2011: Information Technology – Service Management
ISO/IEC 38500:2008: Corporate Governance of Information Technology
ISO/TC 258: Project, Program, and Portfolio Management
Information Technology Infrastructure Library (ITIL)
Control Objectives for Information and Related Technology (COBIT)
Business Process Framework (eTOM)
The TOGAF® standard
The ArchiMate modeling language
