The Open Group IT4IT Reference Architecture standard is focused on defining, sourcing, consuming, and managing IT services by looking holistically at the entire IT Value Chain. While existing frameworks and standards have placed their main emphasis on process, this standard is process-agnostic, focused instead on the data needed to manage a service through its lifecycle. It then describes the functional components (software) that are required to produce and consume the data. Once integrated together, a system of record fabric for IT management is created that ensures full visibility and traceability of the service from cradle to grave.
IT4IT is neutral with respect to development and delivery models. It is intended to support Agile as well as waterfall approaches, and lean Kanban process approaches as well as fully elaborated IT service management process models.
The IT4IT Reference Architecture relates to TOGAF, ArchiMate, and ITIL as shown below:
