• Stand alone.

• Modules can import/export data but not dependent

• Represented a complete end-to-end process by itself.

How did we get here ?But Data Became “Real Time”

• Not acceptable to slowly import/export data between applications

SOA ApproachesDoes it matter ?

For each project expose, compose & consume

Start with implementation finish with business model

Start with business model finish with implementation

Top-Down Bottom-Up Middle-Out

Whichever you choose, same steps different order.None of these approaches say “Start tool shopping…”

A Full SOA Model

In a perfect world, SOA would follow three top-down stages…

Collaborative Modeling

Service Oriented System

Construction

Collaborative Operation

Multi-views business modelling describes enterprise business

Business model is transformed into platform independent business collaborative model

Platform-independent business collaborative model is mapped into platform-specific business collaborative model

The three milestones of SOACollaborative modeling

Collaborative modeling

Build service component libraries

The services in these libraries can be composed and choreographed

The three milestones of SOA

Service oriented information system construction

Service modules in enterprise information systems are identified, encapsulated and published into business process services

Analyze and Optimize the performance of the enterprises business processes by a workflow management system

Enforce business policies and regulations

The three milestones of SOA

Collaborative operation and evaluation

Monitor enterprise business processes

Challenges

We have a large number of existing systems in older technology & architecture models to maintain & integrate.

SOA tech has entered bottom-up, without methodologies & process, because “just connecting things using SOAP” is fast and easy.

We have project and business deadlines that don’t care about architecture, they just want to get it done NOW.

SOA Technology without Methodology leads to…

Connection Spaghetti

Process Duplication

Reduced Reliability

Data Duplication

Major Support (Root Cause Identification)

Challenges

Hard to identify process impact, impact of changes

and system modifications and upgrades

SOA Methodology Provides Measurable Value

Adjustments for Each Stage

Measurements for Each Stage

Keeps the SOA ROI Positive

Provides Describable Business Value

Every Stage of the Software Development LifecycleRequires Tweaks to Achieve SOA Success & Get Real

Without Methodologies and Process Changes to MatchThe Technology Change, the IT Organization will Suffer

Reuse?

SOA Value: Myth or Reality?

Cost Savings?

Agility?

The Promised SOA Advantages are Not Theoretical,But Require Planned Process Changes To Be Gained

Faster Development?
