Quite an enjoyable course.  Would take other courses in future.

This has been an eye opening experience. Receiving this training from the masters will most certainly keep measurable benefits going forward. John provided additional concepts and practices around implementation strategies, a critical next step in exploiting the framework ontology - this was great!!!

Hour-for-hour, this is the best seminar I have attended. The instructors thoroughly covered concepts, demonstrated their application effectively and convincingly explained the consequences of poor architectural practice.

It was the honor to have met and learned from the legendary John A. Zachman himself, the Father of Enterprise Architecture. True Enterprise Architecture starts with Zachman Framework; otherwise, you are just wasting time.

I have been doing Enterprise architecture since 2003, mostly DoDAF and TOGAF. Until I took the Zachman EA 4 day class, I didn't realize that all I had been doing was drawing incomplete views, since I didn't truly understand the relationships and the real impact to an organization of making a change to an architecture element. This class has shown me the importance of getting down to the "brass tacks" of an EA, namely the Zachman primitives and their relationships. I now realize that I have not been truly been doing EA up to this point, since I have not been identifying the organization's primitives!

The Zachman Framework training enabled me to fully understand the power of this framework (the ontology). The fundamentals of this framework will help me to (re)engineer Enterprises and solve business problems in the shortest possible time. As a free-lance Enterprise Architect my customers will benefit the knowledge and Case studies John and Sunil shared with us.

If you want to synthesize your professional experiences...
If you want to expand your understanding of Enterprise Architecture...
If you want to interact with others who think and talk like you do, and learn from the very best, then the Zachman International courses are for you!

Enterprise architecture, as a formal discipline, has arguably reached its ‘tipping point.’ Organizations are howling for change. Even in the current economic down-turn, savvy companies are turning to EA and The Zachman Framework for help. Getting Zachman Certified is dollar-for-dollar the smartest investment an architect, any architect, can make. Don’t think about it too long... get certified and join the growing community of Zachman Certified professionals.

Once more I was able to pick-up new ideas and a couple of valuable best practices. Also the EA energy injection by John Zachman was once more a highlight for me.

I was anxious about my decision to take the virtual class but felt like I was in the classroom with you all. Great job!

Mr. Zachman is the thought leader in enterprise architecture! I am so honored to have met him at training in Colorado and then again last October at a conference in Washington D.C. Through his publications and training - his efforts to raise the bar for enterprise architecture make him the world renown professional he is today. He IS the father of enterprise architecture. His work has helped to drive strategy execution and subsequent business outcomes through his ontology, strategy mapping, matrixes and models.

John Zachman presents a very compelling argument, that is, every organization needs an Enterprise Architecture to survive.

Jane Stewart

Many wide ranging examples to demonstrate why. Engaging and entertaining.

Andre Gauthier

The explanation of the framework itself and the meaning of the components were most helpful.

The enthusiasm, energy and breadth of experience remain, as ever, infectious and mesmerising. Your continued support for John over the last few years is clearly appreciated and probably instrumental in his continuing to return to the UK. Further workshop and/or seminar opportunities are eagerly anticipated. This week has been money very well spent.

John Zachman gave me an excellent insight into the way EA practitioners think and operate, enabling me to express an organisation (as business architecture models) in their language.
