EA methodology implementing

The following diagram shows how an EA project be implemented.

The 4 phases are quite same in different methodologies. And the thread is clear in defining ‘‘where, what, why, who, and how we do architecture’’.

The main aspects are as follows:

Define the architecture principles that will inform any architecture work

Define the framework to be used

Define the relationships between management frameworks

2) Identify the key elements influence the organization: architects should understand the motivation inside the industry, to ensure that in the new plan implementation, the framework design is suitable for the enterprise.

4) Identify framework principle, link it with organizational value and motivation: different organizational value means distinction in organizational culture, structure and the attitude in treating risks.

5) Understand architecture governance:

6) Combine the architecture development process with other management framework: ADM can be used as an independent method, and can also be integrated into other frameworks.

7) Make architecture maturity assessment: Use Capability Maturity Mode to judge the readiness of changing with adopting EA method.

8) Bring architecture functions into the organization:

9) Customize TOGAF:

10) Documentation system.
