Questions and Answers

What approach does the author suggest we take when analyzing software costs?

  • Asking why software costs so much
  • Comparing software costs to hardware costs
  • Focusing on making software cost less (correct)
  • Ignoring the factors influencing software costs

    • How does software cost management differ from managing manufacturing projects according to the text?

  • Software projects can be managed like manufacturing projects
  • Software projects do not wear out like manufactured products (correct)
  • Software projects have higher manufacturing costs
  • Software projects require less engineering effort

    • What is a key difference in failure rates between software and hardware, as mentioned in the text?

  • Software failure rates depend on design defects only
  • Hardware has no failures whereas software does
  • Hardware has a high failure rate initially that drops over time (correct)
  • Software has an increasing failure rate over time

    • Why is it mentioned that software cannot be managed as if it were a manufacturing project?
