8. Why Service Oriented Architectures?

9. Why SOA? Businesses have spent billions of dollars on IT systems Businesses have spent billions of dollars on IT systems Most IT systems are isolated, but there is a business need for them to interoperate Most IT systems are isolated, but there is a business need for them to interoperate Businesses are far more dependant on partners and suppliers (think JIT Inventory, supply chain management, demand visibility) to be competitive and profitable (reducing inventory levels) Businesses are far more dependant on partners and suppliers (think JIT Inventory, supply chain management, demand visibility) to be competitive and profitable (reducing inventory levels) Even for simple transactions there can be a large amount of data required to drive internal and external processes Even for simple transactions there can be a large amount of data required to drive internal and external processes SOAs have the potential to reduce friction (more efficient, productive and more competitive) SOAs have the potential to reduce friction (more efficient, productive and more competitive)

18. Technology Impact on Business Save time. Slash costs. Increase profits… Save time. Slash costs. Increase profits… At the end of the day, these are the business results that count, not processing speed, throughput, or software architecture. At the end of the day, these are the business results that count, not processing speed, throughput, or software architecture. Technology should maximize business value and create new opportunities for success. Technology should maximize business value and create new opportunities for success.

19. SOA ROI “SOA doesn’t guarantee ROI just like the use of technology doesn’t guarantee ROI” – Martin “SOA doesn’t guarantee ROI just like the use of technology doesn’t guarantee ROI” – Martin “Bad ideas and bad projects won’t get better by using technology including SOA” – Martin “Bad ideas and bad projects won’t get better by using technology including SOA” – Martin Often a single SOA project will take more time, money, planning then just writing an app Often a single SOA project will take more time, money, planning then just writing an app If you look across a portfolio of projects SOA savings (capabilities) can add up, but will require substantial executive support since they are cross enterprise projects If you look across a portfolio of projects SOA savings (capabilities) can add up, but will require substantial executive support since they are cross enterprise projects

21. SOA ROI Opportunity Areas SOA provides potential ROI (business value or results) in six basic categories: 1. Reducing expense 2. Increasing asset reuse 3. Increasing business agility 4. Reduction of business risk 5. New sources of revenue 6. Improving efficiency

27. Allstate

28. Allstate (1) By using Web Service Enhancements (WSE), Allstate saved millions of dollars in development costs by extending the functions of an application instead of duplicating them. At the same time, Allstate created the foundation for a service-oriented architecture that will accelerate future integration projects.
