Safety Failures
Therac-25 safety failure:• approximately 100 times the intended
dose of radiation
• 3 people died, and 6 got injured
see article at: http://sunnyday.mit.edu/papers/therac.pdf
Factors:• Overconfidence in
Software
• Confusing reliability with safety
• Lack of defensive Design
• Failure to eliminate fault causes
• Inadequate software engineering practices
• …
SEA Group
Failures, that impact “a lot” of people…
The Skype pervasive failures:• Black out for two hours
• Europe, Japan, Australia, Afghanistan, Sud Africa, Malesia and Brasil havebeen affected
SEA Group
and many more…[Fatal Defect, Ivars Peterson, 1995]
Half book is about failures in software development
SEA Group
… need …To Design Software
→ Software development has to be a systematic activity
(Early) Quality Assurance→ To discover issues as soon as possible
Abstraction:→ To take complexity managable
For achievieng those goals, this course will use a:→ Model-Driven Engineering approach

What You Will Learn in This Course→ Software architectures
─ SA styles─ Architecture Description Languages─ Design Decisions─ Views and Viewpoints─ …
→ Non Functional Modeling and Analysis of Software─ Performance modeling and analysis─ Reliability modeling and analysis─ AEmilia─ …
