  2. Introduction • Software Engineering • Course Outline (http://cs.calvin.edu/curriculum/cs/262/kvlinden/) • Christian Perspective

  3. Software Engineering • Software Engineering is the application of engineeringprinciplesto the developmentof software systems. • Its goal is to produce systems that are:

  4. Art, Science or Engineering Is software development an artistic, scientific, or engineering discipline? • “Computer Programming is an Art … Programmers who subconsciously view themselves as artists will enjoy what they do and will do it better.” • Donald Knuth, Turing Award Speech, 1974 “Computer Science is no more about computers than astronomy is about telescopes. … Science is not about tools, it is about how we use them and what we find out when we do.” - E.W. Dijkstra, Computing Research News, 1993 “Software in all of its forms and across all of its application domains should be engineered.” - Roger Pressman, Software Engineering: A Practitioner's Approach, 2010 image from: http://www.amazon.com/

  5. Art, Science or Engineering Is software development an artistic, scientific, or engineering discipline? “During software design, I’m an architect. While I’m designing the user interface, I’m an artist. During construction, I’m a craftsman. And during unit testing, I’m one mean SOB!” - S. McConnell, IEEE Software, 1998 image from: http://www.stevemcconnell.com/

  6. Software Development • “…developing quality software is hard. In between the nice ideas, the requirements or the “vision,” and a working software product, there is much more than programming.” - P. Kruchten, Forward to Applying UML and Patterns, 2005, p. xix • The required skills include:

  7. The Development Process • Software Development includes the following phases: • Analysis • Design • Implementation • Testing • Maintenance

  8. Software Systems • Software systems are becoming pervasive. • Pervasiveness brings risk.

  9. Case Study: Therac-25 • Medical linear accelerator (1985-87) • The Problem: Two patients died of radiation overdoses. • The Reason: image from kanboy.net

  10. Case Study: Virtual Case File • The Problem: FBI’s $100 million project was abandoned in 2005. • The Reason: image from www.ffbi.gov

  11. Case Study:Playstation Network • The Problem: Sony’s Playstation network was hacked in 2011 compromising personal data. • The Reason: image from sony.com

  12. Case Study: WSJ Mobile App • The Problem: The Wall Street Journal’s iPhone application fails in 2011. • The Reason: image from www.flightglobal.com, Sept, 2007

  13. What’s the Big Idea Fredrick P. Brooks (1931- )The Mythical Man-Month Joys of programming We enjoy designing things because we are created in the image of God. The computer is a powerful and rewarding tool to use. Woes of programming The “mindless” details can be excessively tedious. Products become obsolete too quickly. As the child delights in his mud pie, so the adult enjoys building things, especially things of his own design. I think this delight must be an image of God's delight in making things, a delight shown in the distinctness and newness of each leaf and each snowflake.- F. P. Brooks, Jr. The Mythical Man-Month, 1975 images from: http://www.amazon.com/
