WHY OEAF ?

WHAT IS OEAF ?

• Oracle Enterprise Architecture Framework (OEAF)• OEAF is a hybrid EA framework, influenced by

TOGAF, FEA and Gartner.• Providing “just enough” structure, which can be

created “just in time” to meet the business requirements of the organization• help customers align their IT and business

strategies• OEAF may be used standalone or as a

complement a customer’s selected EA methodology.

5

KEY VALUES

• Driven by business strategy .• Standardizes and simplifies the technical

architecture. • Comprises “just enough” modeling for enterprise

solution architecture efforts. • Reuses best practice business models and

reference architectures from industry and commercial vendors.

6

KEY VALUES (CONT.)

• Developed collaboratively with business owners, stakeholders, and skilled architects. • Developed iteratively and matures evolutionarily

for breadth and depth. • Can be enforced. • Technology agnostic but leverages Oracle

expertise and IP.

7

VALUE & BENEFITS

The Oracle Enterprise Application Framework provides significant value to an organization, including: • Continuous alignment of business and IT.• Improved Return on Investment (ROI) through better

execution of the business strategy using IT, and more efficient reuse of IT resources.

• Leveraging technology to create new business strategies.

Input

Current State Analysis

1. The future state architecture artifacts2. A set of architectural gaps3. A set of architectural recommendations and a cost-benefit analysis

Output

Future State Architecture

26

ORACLE ARCHITECTURE DEVELOPMENT PROCESS

The Strategic Roadmap should produce the following key artifacts:1. A prioritized list of architecture recommendations based on the list from the Future State Architecture phase2. A set of transition architectures that progress the current state to the desired Future State using those architecture recommendations3. A project implementation plan implementing each transition4. A cost analysis of each project implementation and a benefit analysis from each transition architecture

27

ORACLE ARCHITECTURE DEVELOPMENT PROCESS

• The key purpose of the EA Governance Phase is to help customers develop a governance strategy that has one single mission: ensure a successful transition to the desired Future State Architecture.

• Measure the following dimensions:

• People: defined key performance indicators (KPIs)

• Processes and Policies: The basic objectives of processes and policies should

be alignment, performance measurement, and communication of new

requirements and strategies.

• Financials: measure and ensure progress in terms of business

benefits, such as lowering data storage costs by 50%.

28

ORACLE ARCHITECTURE DEVELOPMENT PROCESS

• The Business Case phase provides a cost-benefit analysis for the architecture and resulting IT projects in the roadmap. • This phase can be initiated at the beginning of

the OADP lifecycle since having a focus on the business case can drive decision in almost every phase of the process, such as Current State, Future State, and Strategic Roadmap analysis.
