Why is Architecture Important?
3
The primary link between benefit and cost.
High leverage on an organization’s activities.
Relatively small portion of an organization’s efforts
Yet dictates majority of work!
Source of competitive advantage.
Good architecting provides:
Leverage within one project.
Cross project commonality.
Good interface control.
Creative new solutions.(E. Crawley)

Study questions
What were the design choices made in MOBI.E?
What functionality was given up?
Is MOBI.E considered to be ‘well’ architected?
According to the current architecture principles.
Is it future ready and foolproof?
Is it flexile, scalable, agile and adaptable?
Have we discovered anything new about
architecting during MOBI.E?
What can we add to the body of architecting knowledge?

Why are we doing all this?
Understand tradeoffs in design practice.
Recommend improvements in Mobi.E design.
Any showstoppers in current design?
Extract best practices from industry.
Integrate them into theory & future design.
Where are the biggest gaps between theory and practice???
