These slides are for novice visitors (e.g., my parents) who are not into CS. The actual thesis is rooted in dozen two peer-reviewed conference papers. Furthermore, worked with numerous, world-class companies in helping and improving their architecture and quality.

4. About the cover cartoon
• Financial loss due to poor engineering
• Each module looks good but poor quality as a whole
• As-built structure ≠ specified structure
Our Research:
 How to analyze and improve quality of software whose
structures are invisible
4

5. Software is everywhere in our society
But it’s invisible – you don’t see it

6. Software errors are also common
Crash: mismatch foot vs. meter Killed: radiation overdose Loss: mix quantity and price
Typical reasons for errors:
• Flawed and complex design
• Not designed for testing
• Lack of independent reviews

7. Characteristics of industrial systems
Several languages in a system
Too much software Unknown modules at runtime
• Need computer-aided methods for repeatable and efficient analysis
 to avoid software errors in the field
Family of systems Distributed systems 7

8. Typical questions of the ADAM
System structured for testing? Equivalent modules behave in
the same way?
 Need to discover architectural views
from software to answer
Will it run fast? Unrelated concepts separated?

9. Typical outputs of the ADAM
Modules difficult to test &
Structural errors (shortcut) Behavioral errors
maintain
