WHY OEAF ?

3

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.

4

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.

5

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.

6

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.

Business Objectives and Strategies Architecture Principles

Current State Analysis

1. The future state architecture artifacts 2. A set of architectural gaps 3. A set of architectural recommendations and a cost-benefit analysis

Reference Models and Architectures

25

ORACLE ARCHITECTURE DEVELOPMENT PROCESS The Strategic Roap should produce the following key artifacts: 1. A prioritized list of architecture recommendations based on the list from the Future State Architecture phase 2. A set of transition architectures that progress the current state to the desired Future State using those architecture recommendations 3. A project implementation plan implementing each transition 4. A cost analysis of each project implementation and a benefit analysis from each transition architecture 26

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 of business

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

27

ORACLE ARCHITECTURE DEVELOPMENT PROCESS • The Business Case phase provides a cost-benefit analysis for the architecture and resulting IT projects in the roap. • 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 Roap analysis.
