A quick walk through to establish Enterprise Architecture using the TOGAF’s Architecture Delivery Method.

1. Cursory Walkthrough to establish
Enterprise Architecture using the
TOGAF’s
Architecture Delivery Method

2. Enterprise Architecture Capability
Enterprise Architecture Capability is an ongoing practice that
provides the context, environment and resources to govern
and enable architecture delivery to the organization.

3. The Enterprise Architecture Capability
The enterprise architecture capability will enable enterprise to
1. works with the business planning team to provide business direction and run the enterprise.
2. provide direction to the Portfolio/Project Management team, after the Business planning team approves the resources
3. provide guidelines, reviews as a part of the architecture governance to the solution development team during the
development process
4. provide directions to deploy the solution and continuously monitor the deployed solution in co-ordination with the
Operation Management team

4. What you need to do?

5. Create an Enterprise Architecture Board
An architecture board is responsible to align IT strategies to the business
objectives.
The recommended size for an Architecture Board is four tor five( and no
more than ten) permanent members.
An architecture board is typically made responsible, and accountable, for
achieving some or all of the following goals:
•Consistency between sub-architectures
•Identifying re-usable components
•Flexibility of enterprise architecture:
•To meet changing business needs
•To leverage new technologies
•Enforcement of Architecture Compliance
•Improving the maturity level of architecture discipline within the organization
•Ensuring that the discipline of architecture-based development is adopted
•Providing the basis for all decision-making with regard to changes to the
architectures
•Supporting a visible escalation capability for out-of-bounds decisions

6. Setup the Enterprise Architecture Framework
1. Define Architecture Vision and
Principle and Requirements
2. Define Business, Information
and Technology Architecture
domain
3. Setup a model for the
Architecture realization

7. Setup the Enterprise Architecture Framework
Use TOGAF 9.0 Architecture Development Method(ADM)
to create an enterprise architecture
The TOGAF Architecture
Development Method
(ADM) provides a tested
and repeatable process for
developing architectures.

15. Summation

16. Summation
The TOGAF’s Architecture Development Method (ADM)
process can be adapted to deal with a number of different
usage scenarios, including different process styles (e.g.,
the use of iteration) and also specific specialist
architectures (such as security).
