This document discusses prevailing myths in enterprise architecture and compares the Zachman Framework approach to methodology-driven frameworks. The Zachman Framework focuses on creating single-variable, primitive models that can be composed to dynamically address business problems. In contrast, methodology frameworks provide a fixed set of artifacts. The document provides examples of how the Zachman Framework could be used to create models to solve problems like IT application rationalization. It also discusses managing the transition to more flexible, ontology-driven approaches and certification programs for becoming a Zachman-certified enterprise architect.

2. Let me explain this with some example
1. Prevailing confusions and myths in the  Example 1 - enterprise wide primitive
industry about Enterprise Architecture models based on Zachman
and the practice framework
2. Key focus of Zachman Framework  Example 2- list of artifacts created
deliverables vs Methodology framework using TOGAF
deliverables  Example 3- compare the number of
3. How difficult to solve the problem in relationship & matrices created using
absence of relevant models Zachman Framework vs TOGAF
4. Managing transition to Ontology
driven enterprise  Sample enterprise problems - 9
5. Why do we need to create enterprise problems identified
x-ray on the fly to solve specific  Sample : IT Application

“primitive” models

9. Problem 1 – IT Application Rationalization
How many artifacts are needed to describe the concerns
1.Dependency of apps on each other
2.Dependency between Apps and the interfaces
3.Apps being used in different locations
4. Data model corresponding to each app?
5. User Interface (Screens) to apps mapping
6. What are the key business rules and the apps
automating those rules?
7. Which business processes are being automated by
which app?
8. What are the key requirement's being implemented
by which app?
9. Who are the users and where are they (location)?
10. Which business function uses the app?
11. How does App is responsible for meeting the
strategy of the organization?
12. How does App responsible for meeting the strategy
of the organization?

the problems?

13. Zachman Framework & Certification - comparison
1.Provides ontology of Enterprise Architecture
2.Focus on creating single variable primitive models
3.Creating composite architecture models from
primitives
4. Ability to create the enterprise X-rays for effective
diagnosis
5. Ability to create the multiple solution models quickly
6. Understand the structural flaws resulting in
enterprise dis-orders
7. Number of possible relationship matrices which are
explicitly defined
8.Rules for transformations across the models are well
defined
9.Relationship between performance measurements &
enterprise structure
10.Certification Test – Level 1 – objective type
11.Certification Test – Level 2 – iCMG
