  11. 11. SOA BENEFITS IN TELECOMMUNICATIONS<br />1/3 subscribers on 3G networks by 2010<br />Over US $1 trillion with 66 percent from 3G <br />Offer increasing levels of value and differentiation<br />Developed easily<br />Deployed quickly<br />Altered efficiently<br />鄭遠祥 98753026@nccu.edu.tw<br />11<br />
  12. 12. Research by Forrest and IBM<br />35 SOA projects<br />Increased flexibility<br />97% decreased cost<br />71% reduced risk<br />51% increased revenue<br />43% enabled new products<br />Sprint<br />The Locator application (integrated with GPS)<br />鄭遠祥 98753026@nccu.edu.tw<br />12<br />

CONCLUSION<br />Deal with Increasing levels of software complexity<br />The future success depends on <br />more mature models /reference architectures / capabilities<br />More coherent / Less conflicting - Web service standards<br />Good ideas are not adopted automatically. They must be driven into practice with courageous patience.<br />鄭遠祥 98753026@nccu.edu.tw<br />22<br />
