Welcome to our TOGAF® space!

This public face of the Celestial Consulting wiki has been specifically designed to allow anyone to self study TOGAF®. It consists of useful resources for further study or as an aide to their new roles and towards the TOGAF® exams. We do not recommend you attempt to sit a TOGAF® exam by using this space as an excuse for not attending a TOGAF® training course somewhere, or following the TOGAF® Self Study path.

Why Enterprise Architectur- e

The Complexity of the Enterprise

Modern businesses can be visualised as living organisms with many cell types interacting in very complex ways in an attempt to deliver services to customers.  These interactions have to be fluid so as to ensure that they can continue to be competitive and agile enough to respond to customers who are becoming more savvy and demanding more for less.

Enterprise architecture is there to support the business in achieving its goals, in moving forward, in remaining competitive, in being agile


TOGAF defines and makes use of four domains for understanding the nature of an enterprise, and for defining the current and target state of that enterprise

I define Enterprise Architecture as

The systematic approach to capturing the current and target state of a system viewed through the structural and dynamic characteristics of the components (things: roles, processes, organisational structures, policies, goals, drivers, objectives, locations, services, functions, capabilities, applications, interfaces, software libraries, interoperability models, software standards, data standards, data models, security models, data strategies for DR and BCP, technology portfolio and the list goes on) that are embodied in that system.  Let's see why I say this "the town planning concept."
