Motivations

• 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

• 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, ...

• Two major motivations for explicit architecture

– Change and Complexity

The challenges1. How do you keep track of business requirements?

– 50-100 proposals every quarter

– Prioritize and avoid conflicts

2. How do you keep track of a very large and complex portfolio of IT-systems ?

– Several hundred systems

– Several thousand interfaces

3. How do you asses the impact of changes ?

– More than 100 major IS/IT-projects each year

– Most projects impact several systems and interfaces

4. 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

... and the answers are:

1. Go beyond the technical issues

– “Understand”

2. You need to reduce the (apparent) complexity by defining building blocks and abstractions

– ”Simplify”

3. You need to build a tool that identifies where and how functionality and data is located

– ”Document”

4. You need to build a common language and communication tool

– ”Communicate”
