TOGAF 9 Advanced Bridge Exam

Last week I took - and passed - the TOGAF 9 advanced Bridge Exam 🙂

Here are my two cents  I can share (without breaking the NDA every candidate must agree to at the beginning of the test):

  • the main thing to keep in mind when preparing for the test is that Enterprise Architecture is NOT about building better IT systems, it is about helping to build coherent Enterprises. The TOGAF four architectural domains - business, application, information and technology - come together to support business objectives, not technology ones.
  • The exam has two sections: one is testing candidate's knowledge of the basic concepts and terminology, and the other presenting a plausible scenarios, and asking the candidate to point out the most appropriate one. The passing grade is 60%, and one must score at or above this grade on both sections...There is ample time to finish the exam - that is, if you know your stuff
  • This is an open book test but it won't help to come up with answers even for the first section, leave alone the second one. Besides the TOGAF 9 manual I highly recommend purchasing sample questions/scenarios from the TOGAF bookstore at nominal fee ($3.95); the next best thing are samples prepared by Chris Eaton; safely ignore everything else that pops up when you search the Net on "OG0-9AB sample questions" - these are worse than useless.

Good luck!


Oracle EA Master Class: afterthoughts

Recently I have spent three days in Oracle Enterprise Architecture Training, and - somewhat to my surprise - found it rather useful! Oracle Enterprise Architecture Framework is an interesting perspective on TOGAF with a healthy doze of Gartner (more about it later)

As a lifelong data aficionado, I was heartened to see that a distinction has been made between "Data" and "Information". I have long advocated this distinction, and even had expressed it as a formula in my blog some time ago:  data + context = information. Oracle also adds metadata to the equation (data + metadata + context). I think this takes the above formula to a different level as it implies structure and data governance.

Since the Oracle Enterprise Architecture Framework was announced in 2009 at Open World conference, it did not make it into the great comparison article by Roger Sessions of ObjectWatch,Inc.; high-level white paper describing OEAF can be found here.

The article "A Comparison of the Top Four Enterprise-Architecture Methodologies"  represents a very worthwhile reading for anyone interested in Enterprise Architecture; presently, I am entertaining an idea to apply Roger Sessions' methodology to add OEAF to the comparison matrix 🙂
