The Open Group IT4IT? Reference Architecture, Version 2.1, 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 CorrectEach 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 chainThe audience for this standard is:∗ IT Professionals who are responsible for delivering services in a way that isflexible, traceable, and cost-effective∗ IT Professionals / Practitioners who are focused on instrumenting the ITmanagement landscape∗ IT Leaders who are concerned about their operating model∗ Enterprise Architects who are responsible for IT business transformationTopics 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.
