A Rapidly Changing Business Environment
The Demands on IT are rapidly Evolving Due to
Significant changes in Business Models, Business
Requirements, and Business Processes

• Economics globalization demands flexibility
• Business processes changing quickly and
  sometimes outsourced
• Growth at the top of the CEO agenda
• Reusable assets Leverage what you have
• Information greater availability for Decision
  Making
• Cost Control Do more with less

Changes Business Expectations of IT
Business dictates that IT executives manage IT as
both a commodity service and for competitive
advantage two very different requirements!
ITs Janus Effect Deliver Basic IT Services
AND Competitive Advantage
Deliver new services!
Lower my costs!
Commodity Service Basic IT Services Keeping the
Lights On Offshore / Outsourcing
Competitive Advantage Business Agility IT
Innovation Emerging Technology

• The business requires technology leaders to
  anticipate and respond to these market challenges
  with relevant initiatives in both areas

New Solutions must support both of these Business
Objectives Simultaneously

Two Sides of Legacy Applications

• Its an asset!
• Functional
• Customized
• Well-tuned
• Supports mission critical operations
• Robust
• Secure

• Its a liability!
• Uses old technology
• Requires hard-to-find skills
• Lacks documentation
• Is hard to maintain
• Resists change, integration, and replacement
• Inhibits organizational agility

Forrester Paper
SOA and Mainframe Users

• Interviewed 20 mainframe users around the world
• Identifies SOA best practices
• Strongly communicates that you do not have to
  replace your mainframe applications to achieve
  the benefits of SOA
• Supports 3D Blueprints initiative
• External release May 15th

What are businesses doing?

• Forrester research commissioned by Unisys
• Using incremental development and delivery
  strategies and avoiding big bang investments,
  organizations can leverage their mainframe legacy
  assets and achieve strong business value as they
  evolve from yesterdays architectures to
  tomorrows SOA-based foundation.
• Key criteria used to determine approach
• How well do existing applications fit future
  business needs?
• Is there on-going support for the platform?
• How does the application fit within the overall
  portfolio?
• What are the costs, risks, and elapsed time to
  replace?
• In most cases businesses opted to adapt/evolve
  applications through SOA technologies rather than
  replace
