  1. Software Engineering I Dr. Naveed Ahmad

  2. Introduction

  3. 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

  4. Motivation

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

  6. Where can we find software?

  7. Some popular ones…

  8. Some popular ones…

  9. And even in…

  10. Conclusion Software is almost everywhere!!!

  11. 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

  13. But that never happens? right?

  14. Wrong!

  15. Ariane 5 Flight 501 • Cause: design errors in the software • http://www.youtube.com/watch?v=kYUrqdUyEpI

  16. Conclusion • Programming is NOT enough! It is not enough to do your best: you must Know what to do, and THEN do your best. -- W. Edwards Deming

  17. And Since… A clever person solves a problem. A wise person avoids it. - Albert Einstein

  18. Solution

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

  20. 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.

  21. Recommended Books • Text Books • Roger S. Pressman, Software Engineering, A Practitioner’s Approach, Latest Edition, 2005. • Ian Sommerville, Software Engineering, 2000.
