Problem 1
Explain how advances in technology can force a software subsystem to undergo change or run the risk of becoming useless.
Problem 3
Explain why legacy systems should be thought of as sociotechnical systems rather than simply software systems that were developed using old technology.

Problem 6
Explain why problems with support software might mean that an organization has to replace its legacy systems.
Problem 8

Problem 9
Explain the differences between software reengineering and refactoring?
Problem 10
Do software engineers have a professional responsibility to develop code that can be easily maintained even if their employer does not explicitly request it?
