Sometimes, isn't redundancy and complexity necessary or even desirable? For instance, isn't a large retailer more successful with thousands of redundant stores and massive complexity?

You can have as many instances (redundant retail stores) as you want in Row 6:Operations Instances, but you only want a single abstraction in Row 1:Scope Contexts, Row 2:Business Concepts and Row 3:System Logic. It is conceivable to have more than one abstraction in Row 4:Technology Physics and Row 5:Tool Components, but if you do, you have to keep track of them as they relate to Row 3:System Logic or else you will go out of control- potentially have an entropy problem. They will get out of sync.
That is, you don't want any discontinuity in the Concepts (Row 2) or the Logic (Row 3). It is conceivable that you might want to implement in more than one Technology (Row 4), but now you have a synchronization problem that you will have to manage.
In terms of Row 6:Operations Instances, there can by "n" of those, but you want each instance to trace back to the Components Transformation (Row 5), the Physics Transformation (Row 4), the Logic Transformation (Row 3), and the Concept Transformation (Row 2), and probably the Scope Transformation (Row 1) as well. That is how you insure that the reality of the Enterprise is consistent with the Enterprise Architecture. And when the "Systems" say there are 423 Employees in stock, there are actually 423 Employees in stock, etc., etc... and when we say the Concept "Employee" (Row 2:Business Concepts), it means the same across the entire Enterprise and that all the Employee instances (Row 6:Operations Instances) obey that authorized Enterprise Concept (Row 2:Business Concepts) definition.
If you did this, you could actually manage the Enterprise.

What is Enterprise Architecture and why do we do it?
What is Enterprise Architecture and why do we do it?
"Architecture is a set of descriptive representations that are relevant for describing something you intend to create and that constitute the baseline for changing an instance of that thing once you have created it. Therefore, Enterprise Architecture is the set of descriptive representations relevant for describing an Enterprise and that constitutes the baseline for changing the Enterprise once it is created." - John Zachman, taken from interview with Roger Sessions, Editor-in-Chief: Perspectives of the International Association of Software Architects
"If you get really honest and search all of history, seven thousand years of known history of humankind, to find how humanity has learned to cope with two things, complexity and change ... there is one game in town, ARCHITECTURE.
If it (whatever it is) gets so complex you can't remember everything all at one time, you have to write it down... ARCHITECTURE. Then, if you want to change it (whatever it is), you go to what you wrote down... ARCHITECTURE.
How do you think they build hundred story buildings, or Boeing 747's, or IBM supercomputers... or even simple things like a one-bedroom house or a Piper Cub or the PC on your desk? Somebody had to write it down... at excruciating levels of detail... ARCHITECTURE. Now, if you want to change any of those things (with minimum time, disruption and cost), how do you change them? You go to what you wrote down... ARCHITECTURE.
The key to complexity and change is ARCHITECTURE.
In the Industrial Age, we had to learn what architecture was relative to physical objects (products) in order to deal with product complexity and product change.
In the Information Age, it is the Enterprise that is complex and changing and therefore, now we are having to learn what architecture is relative to the Enterprise ... Enterprise Architecture.
This is what is making the Framework for Enterprise Architecture so significant in the Enterprise community as we move into the Information Age. The Framework is putting some definition around Enterprise Architecture."

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.

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.

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.
