Perspective
We see all enterprise information as a huge system of loosely coupled components. Separation of concern will be essential for mastering its complexity.
We apply three perspectives on the enterprise:
¤ People use information in their business processes
¤ Information services manage this information
¤ People perform tasks using information tools

6. Area of concern Business Model
The area of concern is the handling
of travel expense accounts.
We focus on the expense account itself,
and do not model details about why the
journey was made, nor how the traveler
is reimbursed for his expenses.

13. The main problems
We spend too much time and effort on low-level mechanics.
Current offerings are NOT:
Easy and intuitive to use
Smooth development platforms
Reliable
Secure
Extensible
Virksomhetens informasjonsnettverk

14. How do we get from here to there?
• Focus on objects
Classes are implementation details
• Learn technology
Java + CORBA + Web + ...
• Do small, but significant project
Illustrating visions
Most of the required technology is available -- but the abstractions will hopefully get cleaner and the middleware platforms simpler.
• Plan large scale introduction
What are the information services?
What are the Areas of Concern?
