The IT4IT Reference Architecture prescribes holistic management of the business of IT with continuous insight and control, enabling Boundaryless Information Flow™ across the entire IT Value Chain – The Open Group
The Open Group IT4IT Reference Architecture standard provides;
- Reference architecture and a value chain-based operating model for managing the business of IT.
- Prescriptive guidance on how to design, procure and implement the functionality needed to run IT.
- End-to-end, ‘how to’ emphasis of the IT Value Chain.
- Enables the state of services that IT delivers to be systematically tracked across the service lifecycle.
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 Fulfil
- Requirement to Deploy
- Detect to Correct
Each IT Value Stream is concentrated 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 critical role in facilitating IT’s control of the service model as it advances through its lifecycle.
In conclusion, 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 complement 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 IT Value Chain is a prescriptive model for how to manage the service life cycle and broker services to the enterprise. The IT4IT operating model allows the IT function to achieve the same level of business discipline, predictability and efficiency as other functions in the business.
