Key Findings:

• Service-oriented architectures built upon open, standards-based Web Services provide a strategic IT direction businesses need to meet their fundamental business goal: agility.
• By 2010, ZapThink expects 69% of the total enterprise software market to be Service-oriented.
• The overall market for products and services that support Service orientation will be over $98 billion by 2010.
• Reworking existing brittle, high-cost IT infrastructures into flexible, Service-oriented architectures promises substantial long-term cost savings and revenue opportunities through increased business agility.
• Service orientation represents the latest distributed computing approach to affect IT — the fourth major shift since the mid-twentieth century.
• ZapThink predicts that companies will begin to accept Service orientation in 2003, and it will become the dominant distributed computing approach by 2006.
