Samenvatting

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
