TOGAF 9.1 Series — ADM Phase — H — Architecture Change Management

Have you ever heard of TOGAF and never really understood it? In my TOGAF 9.1 series of articles, I will give you summary points what TOGAF is and what you will learn in TOGAF.

I have written the TOGAF exam a while back. I thought that writing this series will let me review the TOGAF content and believe that it would be valuable to others. It is always a good practice to regularly review the contents of a topic that you have learned.

I’m not going to rewrite the official TOGAF books content in my article series. Some sections will only contain bullet points of key terms used in TOGAF. Always reference the official TOGAF book for more details.

Legal Points

TOGAF is a trademark of The Open Group. They maintain the TOGAF standard and release new versions of the framework. I highly recommend that you read the official website and content of TOGAF on the official site:

The contents in my article series are my opinions and in no way reflects the views of The Open Group.

If you are interested in learning all the finer details of TOGAF or want to write the exam then buy the official book:
