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 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.
