Why need to enhance TOGAF to support SOA?

TOGAF is a mature EA framework that is widely adopted

SOA is architecture style that is beingwidely adopted

Enterprises have adopted both TOGAF and SOA

Struggling to bring the EA work and SOA together

TOGAF practitioners should be able to use TOGAF to deliver SOA

Need to stop looking at the two as separate activities

Overview: TOGAF

What is TOGAF? TOGAF = The Open Group Architecture Framework.

Preliminary Adapt framework phase

Define principles,

Anarchitecture framework that enables you to design, evaluate, and build the right architecture for your organization.

A: Define scope; create H: Establish for vision; obtain approvals procedures for managing A change to new Architecture architecture vision B B: Develop a Business business H Architecture Architecture architecture
Change Management

What architecture style does it support? TOGAFdoesn’t specify the architecture style – it is a generic framework TOGAF can be used in developing architecture based on SOA style.

C
Requirement Managements
Information Systems Architecture

What does it contain? TOGAF consists of three main parts: The TOGAF Architecture Development Method (ADM), The Enterprise Continuum The TOGAF Resource Base

G
Implementation Governance

C: Developdata and application architecture

D
Technology Architecture

D: Develop a technology architecture

G: Provide architectural oversight of the implementation

F
Migration Planning

E
F: Prioritize, select major work packages, develop migration plan
Opportunities and Solutions

E: Check point suitability for implementation
