If you don't understand it, you can't program it.
If you didn't measure it, you didn't do it.

13. What is the Role of
Software ?

14. The role of software
engineering is to capture the
customer’s business needs and
specify the “blueprints” for the
system so that programmers
can implement it

15. Software
Engineering

16. “Software Engineering is the application of
a systematic, disciplined, quantifiable
approach to the development, operation,
and maintenance of software.”
- IEEE’90

17. “Software Engineering is an act of applying
a collection of techniques, methodologies
and tools that help with the production of a
high quality software system,
…with a given budget,
before a given deadline,
while change occurs.”

18. Techniques (Methods)
Formal procedures for producing results using some
well-defined notation
Methodologies
Collection of techniques applied across software
development and unified by a philosophical approach
Tools
Instrument or automated systems to accomplish a
technique

19. Software
Engineering:
A Multi-Disciplinary Discipline

older science &
engineering disciplines
and new ones

22. Why is Software
Engineering Difficult?

23. Because you need to
know about…
1
software domain and
problem domain

24. 2
Software is formal
there is a precise statement of what needs to be programmed
Software Engineering deals only with the software itself
Real World is informal
there is NO precise statement of what needs to be programmed
Software Engineering includes discovering a solution for a real-world problem

25. Software
