THE IT4ITTM REFERENCE ARCHITECTURE, VERSION 2.1

The Open Group IT4ITTM 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 functi
nts (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 guidan
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)
* Embr
and complements existing process frameworks and methodologies (e.g., ITILR, CoBITR, SAFe, and TOGAFR) by taking a data-focused implementation model perspective, essentially specifying an information model across the entire value chain

The a
udience 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
managemen
t landscape
* IT Leaders who are concerned about their operating model
* Enterprise Architects who are responsible for IT business transformation

* An introduction to the standard and the purpose of t
