  7. Introduction • Where did the greatest level of user satisfaction occur? • Why?

  8. Situation • Our model for progress • Situation + Response = Outcome

  9. Situation • Comcast Media Center • Cable industry service provider • Programming, HITS • Advanced Advertising • User Generated Content • Video On Demand (VOD) • Systems Development?

  10. Situation • Legacy Systems and Approach • Former Aerospace personnel • High Availability and Reliability • Waterfall • Long periods between changes

  11. Situation • Challenges • Time to Market • Development Cost • Responsiveness • Silo approach

  12. Response • Adoption of • Collaborative development style • Shared hardware resources • Service Oriented Architecture • BPA Validation method • Test automation

  13. Response • Service Oriented Architecture • Enterprise bus-centric • Modularize functionality • Re-use and re-factor

  14. Response • What - Service Oriented Architecture • Loose Coupling • Consistent interface • Stateless • Discoverable • Shared

  15. Response • Why – Service Oriented Architecture • Optimize re-use • Improve system agility • Simpler integration
