1. Welcome to Software Engineering!

2. You will be dropped if you don’t satisfy these requirements
Computer Science majors should plan to take COMP 4882 during the following spring semester.
PREREQUISITE: COMP 3160

3. What distinguishes software engineering from other types of software creation?
Large Scale
Customers
Teams of Developers

4. What is the measure of a successful software engineering project?
Customer Satisfaction
* OK, effect on society and humanity matters too, but humor me…

5. Meets their needs, On time, On budget What do customers want?
Software that
Meets their needs,
On time,
and
On budget

6. Unfortunately, satisfying customers is hard…
Have you ever been a dissatisfied customer?

7. The “Software Crisis” Since the 1960s (More like a depression)
(Standish Group)
Of 28,000 projects completed in 2000…
(Cutter Consortium)
2002 Study: 78% of orgs landed in court

8. Why is satisfying customers hard? What problems do SEs face?
Software that
Meets their needs,
On time,
and
On budget
Why is satisfying customers hard? What problems do SEs face?

9. Problem: Requirements

10. “The customer is always right!”
But …
Customers may change their minds
Customers may not agree with each other
Customers may not know exactly what they want

11. Problem: Cost estimation

12. Spectacular failure: Denver Int’l Airport baggage-handling system
Largest international airport in the US (by area)
Scheduled to open in Oct ‘93; actually opened in Feb ‘95
Had to buy back up system and scale back first system after deadline had passed
System never did work as intended and was retired in 2005
Problems both managerial and technical
Hard to get precise figures on how over-budget, but one estimate at $3.2 billion

13. Problem: Bugs

14. Spectacular failure: Therac-25 radiation therapy machine
6 overdoses between Jun ‘85 and Jan ‘87.
First overdose:
Breast cancer
“tremendous force of heat… this red-hot sensation”
Reddening, swelling in front; later matching back; tremendous pain
Lost breast and lost use of arm, shoulder
15,000-20,000 rad overdose; 200 rad normal dose; 1000 to whole body will kill
Manufacturer and operators refused to implicate Therac-25
Other cases were similar; one for skin cancer on face resulted in death in one month

15. Problem: Maintenance

16. All successful software will change over time
But such change can lead to design erosion

17. But to effectively apply these approaches requires a lot of experience
What ways have you heard of to overcome these problems and satisfy the customer?
In this course, we’ll learn about:
Agile development
Iterative development
Test-driven development
Object-oriented analysis and design
But to effectively apply these approaches requires a lot of experience

18. Course Goals Significant software project Team skills
Communication skills
Project management

19. What type of software will you build for the project?
Web Apps!

20. Why web apps?
Create apps every bit as dynamic, interactive, and custom tailored as native apps
Avoid deployment problems
Reach people world wide
