1. Introduction

2. Objective
•To familiarize students to the fundamental
concepts, techniques, processes, methods and
tools of Software Engineering,
•To help students to develop basic skills that will
enable them to construct software of high quality
–software that is reliable, and that is
reasonably easy to understand, modify and
maintain
•To foster an understanding of why these skills are
important

6. Motivation

7. Software can have huge impact in
any aspect of our society

8. Where can we find software?

9. Some popular ones…

10. Some popular ones…

11. And even in…

12. Conclusion
Software is almost everywhere!!!

13. Problems in software development
•Common issues
–The final software does not fulfill the needs of the
customer
–Hard to extend and improve: if you want to add a
functionality later its mission impossible
–Bad documentation
–Bad quality: frequent errors, hard to use, ...
–More time and costs than expected

15. Software Engineering
1)The application of a systematic, disciplined,
quantifiable approach to the development,
operation, and maintenance of software; that is
the application of engineering to software.
2)The study of approaches as in (1)
--IEEE Definition (1993)

16. Software Engineering
Objective is to produce software that is:
•On time: is deliver at the established date.
•Reliable: does not crash.
•Complete: good documentation, fulfill
customer needs.
