Caveat: Every project is an individual

4. Characteristics of SE Projects
Large Scale
Customers
Teams of Developers

5. What is the measure of a successful software engineering project?

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

7. What do customers want?

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

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

13. Problem: Requirements

14. “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

15. Problem: Cost estimation

16. 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

17. Problem: Bugs

18. 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

19. Problem: Maintenance

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