Key Issues
1. How will software design and acquisition practices change as managers pursue enterprise agility?
2. What will be the benefits and limitations of the three major integration strategies: rip and replace; wrap or re-engineer; and leave-and-layer?
3. What strategies will bring the most success for enterprises adopting new middleware technologies for the Grid?

The Grid: Why Now?
Enablers
• A critical mass of business functions have been automated with online systems
• Improved integration middleware technologies
• Standards: TCP/IP, SMTP, FTP, HTTP, HTML, XML, Web services
• Hardware: Faster chips mean faster systems and more network bandwidth

Recommendations
• To create an agile enterprise, managers and architects must view the business units, people, application systems and automated devices throughout a virtual enterprise as participants in a holistic system.
• Senior management must be made aware of a subtle, but revolutionary, change in IT architecture enabled by the Grid and ENS.
• Enterprises should explicitly plan and manage their ENSs through a central integration competency center, rather than letting their ENSs emerge piecemeal, unrecognized and uncontrolled.
