6. What is architecture ? Efficient code ? Well structured code ?
Using the right languages and/or tools ?
Well formed and flexible data models ?
Choosing the right suppliers of software ?
To have a cost effective portfolio of systems ?

7. Motivations Two major motivations for explicit architecture Complexity
Change and Complexity
Complexity
SW systems become complex
The context becomes complex
Many usage scenarios
How to convey
Internal structure?
Applicability in different contexts?
Change
Panta rei
Requirements, underlying platform, competitors, market, ...
Change ctd.
Changes should have limited effects
Do not want to have unknown ripple effects
Should define the envelope of change
What is allowed to change without major consequences
Good, old SW engineering principles still apply!
Loose coupling
High cohesion
Flexibility as a competitive advantage
AT&T vs Sprint

15. The challenges How do you keep track of business requirements?
proposals every quarter
Prioritize and avoid conflicts
How do you keep track of a very large and complex portfolio of IT-systems ?
Several hundred systems
Several thousand interfaces
How do you asses the impact of changes ?
More than 100 major IS/IT-projects each year
Most projects impact several systems and interfaces
How do you communicate ?
The way we do business is deeply integrated into the IT-systems, and changes always impact our processes and opportunities
In a large organization knowledge is always spread among several units, no central unit can contain the sum of all relevant knowledge
