The IT4ITTM reference architecture, Version 2.0

Book excerpt: The Open Group IT4IT Reference Architecture, Version 2.0, an Open Group Standard, provides a vendor-neutral, technology-agnostic, and industry-agnostic reference architecture for managing the business of IT. The Open Group IT4IT Reference Architecture standard comprises a reference architecture and a value chain-based operating model. The IT Value Chain has four value streams supported by a reference architecture to drive efficiency and agility. The four value streams are: Strategy to Portfolio Request to Fulfill Requirement to Deploy Detect to Correct Each IT Value Stream is centered on a key aspect of the service model, the essential data objects (information model), and functional components (functional model) that support it. Together, the four value streams play a vital role in helping IT control the service model as it advances through its lifecycle. The IT4IT Reference Architecture: Provides prescriptive guidance on the specification of and interaction with a consistent service model backbone (common data model/context) Supports real-world use-cases driven by the Digital Economy (e.g., Cloud-sourcing, Agile, DevOps, and service brokering) Embraces and complements existing process frameworks and methodologies (e.g., ITIL®, CoBIT®, SAFe, and TOGAF®) by taking a data-focused implementation model perspective, essentially specifying an information model across the entire value chain The audience for this standard is: IT Professionals who are responsible for delivering services in a way that is flexible, traceable, and cost-effective IT Professionals / Practitioners who are focused on instrumenting the IT management landscape IT Leaders who are concerned about their operating model Enterprise Architects who are responsible for IT business transformation Topics covered include: An introduction to the standard and the purpose of the IT4IT work Key terminology of the standard An introduction for executives and others introducing the IT Value Chain and IT4IT Reference Architecture concepts IT4IT Core, which defines the structure of the IT4IT standard as well as the process and document structure used by the IT4IT standard The Strategy to Portfolio (S2P) Value Stream The Requirement to Deploy (R2D) Value Stream The Request to Fulfill (R2F) Value Stream The Detect to Correct (D2C) Value Stream Background information on the standard.
