12. Actor perspective Actor -> will use or do the business Actor activities should be in relations to the system –Services/applications do not exist on their own! Depending on the hierarchy –Data provider vs data consumer Same actor can have different external influences

13. Technology choice Function of business requirements!!!! –Open source – closed source –Cabled solutions allowed? Plan a step by step approach –different levels of communication –Differentiate early adapters/followers Don’t strive for the ideal world –Technology is changing at different levels of multi-tear Choose between services/applications/file based data exchange

14. Conclusions Metaphor –cold –Wooden house or brick house, wood is available – bricks are not but a company might start making them... Use your business and actors as a guide line Services are not always the solutions!

15. Thank you for your attention! And up to a WISE SDI!!
