What’s on the minds of 450 of the world’s leading CEOs?

Source: Operating Environment Market Drivers Study, IBM Corp. 2004

• Aligning IT and business goals to grow revenue and contain costs

• Building responsiveness and agility into the organization through IT

• How can IT help enable people and teams to be more effective

CEO needs CIO challenges


Consistent imperatives ….

… Increase customer satisfaction • Dassault Aviation reduced concept-to-

runway development time by 30%

• British Petroleum decreased user-provisioning time from 5 days to 10 minutes

… Grow faster • Bekins, a moving company, increased

revenue by $75M through integration with business partners to serve a new market

• PineBank increased customer traffic by 300% and revenues by $8M

… Spend less • Kookmin Bank should save $250 million from

reduction of duplicate processes

• Volkswagen realized a 20% productivity gain

Flexibility

Efficiency

Responsiveness


Business flexibility depends on IT flexibility

“Today’s IT architectures, arcane as they may be, are the biggest roadblocks most companies face when making strategic moves.”

–McKinsey “Flexible IT, Better Strategy”

Why are today’s architectures roadblocks?

• Complexity

• Monolithic and silo’d applications

• Hidden interfaces

• Custom coded connections

• Not designed for change

Actual application architecture for a consumer electronics company


Change And Improvement Have Been Daunting

How do I optimize my procurement processes?

Traditional Process Implementations Are Expensive And Slow To Change


Service Oriented Architecture: the blueprint for change

“Service-oriented architecture deployments are increasing and becoming a mainstream architectural model for developing services, applications and infrastructures.”

“Effective Web Services and SOBAs Require Management”Frank Kenney, GartnerSeptember 28, 2004

Why SOA?

• Flexibility

• Facilitates re-use of existing applications

• Supports effective business process implementations

• Designed for change

Aligns Business and IT goals to grow revenue and contain costs


Agenda

Why SOA?

What is SOA?


Summary


• Many technology-aware bridges• Complex and expensive to

maintain

• Single platform-neutral standard • Simplifies and strengthens integration

efforts

Traditional integration Service-Oriented Architecture

Evolving Service Orientations

vs.


Service Oriented Architecture

SOA is an approach to IT that builds business processes from reusable component modules or "services" that are independent of applications and the computing platforms on which they run.

Software assets become building blocks that can be reused in developing other applications

Focus is on application assembly rather than implementation details

Can be used internally to create new applications out of existing components

Can be used externally to integrate with applications outside of the enterprise

SOA – Why is IT the choke point for innovation?

Monolithic applications can’t be reused Ad hoc integration creates connections that are

difficult to change/maintain Lack of standards limits ability to deliver meaningful

interoperability Rigidity of architecture

makes small improvements impossible to cost justify

Summary


Customers Choosing IBM for Service-Oriented Development

“The challenge in today’s IT environment is achieving not just IT efficiency, but rather business effectiveness (doing the right things in the right way). This requires understanding and balancing both the business and IT perspectives of a solution. In our experience, the best way to address this is by adopting a Service Oriented Development paradigm, combined with a model driven approach to describing and implementing solutions.

Models must encompass both the business process perspective, the functional perspective and the data perspective of a solution. We have chosen to adopt Rational Software Architect as a key element of this model driven strategy. We expect through better tooling to achieve both efficiency in development and support for the desired effectiveness in merging business and IT.”

- Claus Torp Jensen, VP, IT Architecture, Competencies and Methods

Business Trends & Pains

Trends Pains

Mergers & Acquisitions

Compliance & regulatory pressure

Complex and brittle systems & architectures

Outsourcing

Modeling: Biz, Architecture, Apps..

Reliance on technology/IT

Rapidly evolving technology

Unprecedented pressure and expectations: overwhelmed! Brittle complex systems & architectures prevent rapid change Skills and systems can’t keep up with evolving technology Overwhelmed by demands – not aligned with business priorities Lack of coordination across lines of business – wasted resources, redundant projects, missed opportunities Unable to deliver new products & capabilities fast enough


Business flexibility is driving the need for IT flexibility

The need for flexibility and innovation is forcing organizations to break their business processes into manageable parts 85% of CEOs say streamlining or

optimizing their business processes are their top priority (1)

Applications mirror this approach, becoming increasingly modular 48% of CIOs say application integration

is their top IT priority (2)

Simplification of underlying IT infrastructure is required to manage and support changes in the business X% of CEOs see IT as an inhibitor to

business responsiveness (3)

Sources: (1) Outlook 2004: Priorities 1Q InformationWeek Research, January 2004;(2) Merrill Lynch CIO Survey Results, September 2004(3) IBM Global CEO Study, February 2004

This is part of what IBM calls “On Demand”


IT Pains

Align business models & processes with strategic

objectives

Standardize, automate and integrate business processes and IT

infrastructure

1. Support company growth

2. Ability to respond rapidly

3. Alignment of disparate applications

4. Have applications better fit business

processes

5. Integrate/Enhance Systems and

Processes

6. Align IT and Business Goals

7. Responsive to business conditions

8. Capture and utilize customer information

for swift decisions

9. Improve Efficiency of business processes

10. Increase flexibility of business processes

11. Work efficiently with suppliers, partners

and customers

12. Building responsiveness and agility into

the organization through IT

13. And many others !

Reuse

Align

Standardize

Extend & reuse existing IT assets


An On Demand Business is an enterprise whose business processes —

integrated end-to-end across the company and with key partners,

suppliers and customers — can respond with speed to any customer demand,

market opportunity or external threat.

Business Flexibility: Becoming an On Demand Business


2005 will be the year of the SOA. Mark it down. According to The Yankee Group, 75% of firms plan to invest in the technology and staffing to enable a service-oriented architecture (SOA).

Gartner, 2004 Gartner Inc.'s prediction that by 2008, 60% of enterprises will use SOA as their "guiding principle" when creating applications and processes Gartner, 2004

In a survey of more than 1000 European developers, Evans Data Corp. found that nearly 75% are currently developing or are planning to develop SOA in 2005

Evans Data Corp, Jan 2005

Linking Legacy Systems to Current Applications - Each successive wave of technology over the past ten years has brought new applications. Mainframes, client/server databases, ERP, Web applications, Java applications, and soon Web services form a mosaic of applications that will likely be present in most enterprises for the foreseeable future. Each new application requires integration with one or more existing "legacy" application

Improving Internal Business Processes - The move to analyze and automate and create new business processes will continue to be a long-term driver. Improving processes is a basic cost-cutting measure as well as a means to increase client satisfaction and gain a competitive advantage.

Improving Shared Business Processes - The need to automate common B2B processes is a basic cost-cutting measure that also serves to make supply chains more efficient. This need will continue to drive the industry in the long term. In particular, standards that enable or mandate these shared business processes will provide a focal point to B2B projects.
