The Open Group has published the IT4IT™ Reference Architecture, Version 2.0, an Open Group Standard. http://pubs.opengroup.org/it4it/refarch20/index.html

IT4IT is a real architecture model, it is well defined with logical elements and definitions of Functional Components and their relationships. It is based on four value streams:

• Strategy to Portfolio (S2P)
• Requirement to Deploy (R2D)
• Request to Fulfill (R2F)
• Detect to Correct (D2C)
