Why I’m Here
• Context:
– Today’s world of business, systems and technology is more complex and dynamic than ever.

TOGAF
• The Open Group:
―The Open Group is a vendor- and technology-neutral consortium, whose vision of Boundaryless
Information Flow™ will enable access to integrated information within and between enterprises based on
open standards and global interoperability.‖
http:/www.opengroup.org
• TOGAF = The Open Group Architecture Framework
– ― ... a detailed method and a set of supporting tools — for developing an enterprise architecture. It may be
used freely by any organization wishing to develop an enterprise architecture for use within that
organization‖
– An effective, industry standard framework and method for Enterprise Architecture
– Demystifies architecture development
– Complementary to, not competing with other enterprise frameworks
– Enables the “Boundaryless Information Flow™” vision
– Began in 1993 and continuously evolved
– Stretching the boundaries of IT into the Boardroom
– Aligning organisation strategy and operational technology

TOGAF 9 – Part IV: Architecture Content Framework
• The Content Metamodel:
– Provides a definition of all the types of building block that may exist within an architecture
– Shows how the building blocks can be described and relate to one another
• Three categories of architectural work product:
– A Deliverable:
• A work product that is contractually specified
– An Artifact:
• A work product that describes an architecture from a specific viewpoint
– A Building Block:
• Represents a component of business, IT or architectural capability
• Is combined with other building blocks to deliver architectures and solutions
