The term "bug" suggests that something just wandered in. In the modern day, bugs don't just wander into our computers

[IEEE 729]

• Fault: result of a human error in software system
  • E.g., implementation doesn't match design, or design doesn't match requirements
  • Might never appear to end user.
• Failure: violation of a requirement
  • Something goes wrong for end user. (i.e. app crashes)

Human Error -> Fault -> Failure
