The IT4IT™ Reference Architecture, Version 2.1

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 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
