Last year:

• OMB required EPA to submit its SOA Strategy as part of the EA deliverables

• The OEI board of directors chartered the Web Services Working Group (WSWG) to develop a SOA implementation strategy for the EPA

Phase I (delivered in December): EPA SOA Strategy document delivered to OMB

EPA SOA Implementation Strategy document reviewed and rated excellent by Gartner

Briefing delivered at OEI symposium

Now in Phase II: Brief OEI Board of Directors and refine strategy

based on feedback

Develop OEI SOA Implementation Plan (in progress)

SOA-enable Enterprise Architecture practices

Key Goals• Help OEI and other EPA offices organize their work

to serve their customers and their leadership more efficiently and effectively.

• Deliver clear business benefits for OEI and the EPA

• Provide actionable recommendations

• Pragmatic, not “pie in the sky”

• Align with architecture efforts underway

• Consistent with the Federal Enterprise Architecture

OEI has developed the EPA SOA Strategy, and is nowdeveloping a more detailed SOA Implementation Strategy and Plan

EPA’s SOA Strategy Overview

Key Principles• Services include both business processes and IT

services, and can exist at all levels of the architecture

• Services, service components, and service level agreements (SLAs) should be defined, cataloged, and published

The EPA has begun using SOA (examples below), but because our efforts aren’t coordinated, we are only getting limited benefit

Assemble systems withmodular services to save

time and money…

Share services acrossorganizations to gain

efficiencies…

Boost satisfactionby focusing on customers’

service needs…

Use new SOA Internet standards to make it easier

to share services…Use SOA infrastructure

to provide and manage trust-worthy services at scale…

Don’t do it all yourself,use providers who specializein the services you need…

Use an agile service lifecycle,not “big bang”, to optimize

business processes…

Focus on services to align“big picture” and detail level

decision making…

CUSTOMERS DISSATISFIED?

TOO HARD TO SHARE?

HERDING CATS?

TOO MANY SERVICES?

PAYING FOR REDUNDANT WORK?

WORK TOO COMPLICATED?

TOO MUCH CHANGE NEEDED?

TOO SLOW AND EXPENSIVE?

Services

... as OIC is doing with CDX Lite

… as OIAA is doing by using GoogleEarth

… as EA is via Segment Architectures

… as the Exchange Network does

… as OEI Portal services can save

… as the WCF services are gaining

… as SLCM can be used if agile methodsand service focus are incorporated

…as CDX does with its SOA infrastructure

Guided by EPA Strategic Information Plan Goals and OEI Board of Director Priorities

1. Implement the SOA strategy within OEI(OEI SOA Implementation Plan)

2. Facilitate SOA implementation across the EPA (Enterprise Architecture)

Develop Service Roadmaps for Key OEI Services(OEI SOA Implementation Plan)

• Information Discovery and Exchange Services

• OEI Enterprise Tools (common enabling services)

• Enterprise Service Catalog Service

• Customer Solution Support Services

• Advanced Collaboration Services

• SOA Foundation Infrastructure Services (ESB, etc.)

• SOA Enablement Center Services

Develop Service Roadmaps for other Key EPA Services (Enterprise Architecture)

Identify and act on opportunities for service improvement (ongoing service focus)

SOA-Enable EPA’s “Top-Down” Management Processes (e.g., Strategy, Budget, CPIC, EA, SLCM)

Increase “Bottom-Up” collaboration in EPA’sSOA Communities of Interest (e.g., WSWG)

Next steps are underway – we need executive support toprioritize and accelerate our key activities

Partner ViewsStrategic

· It's during the definition of segment architectures that you identify services and what they should be providing for the business

Develop Service-Oriented Solutions to Resolve Transformation Requirements

thereby Providing Business Value

Tactical

· Throughout this process, we work to enable Programs to use the EA discipline to think in terms of 'services' as they use architecture to better plan the business lines (Segments) they lead, AND to ready their organizations for any upcoming changes

SOA Planning embedded from Strategy to Implementation

SOA naturally fits into the EA performance improvement lifecycle “Architect > Invest > Implement” with embedded changes

Governance Changes

1. Target Architecture How do we plan and track

the complex dependencies between services?

2. CPIC/Budget Do we require services to

have business cases? How to fund and meter the

use of services?

3. System Life Cycle Should we include SOA

criteria into each control gate review?

• This SOA strategy will help EPA coordinate and get the full potential benefit out of SOA

• We need your support to prioritize and accelerate key activities (“light and fast”):

Focus decision making on services and develop service roadmaps
