Across
  1. 3. A system's external state includes an erroneous state
  2. 5. An approach to building systems where the effects of faults are predicted ahead of time and used to determine dependability
  3. 6. An approach to building systems where faults are removed prior to being used
  4. 12. A type of fault that was predicted ahead of time
  5. 14. Abbreviation of erroneous state
  6. 16. An approach to building systems where faults are absent
  7. 17. Believed to be the cause of an erroneous state
  8. 19. A fault that may not always fail given the exact same input
  9. 20. A fault that results in completely unpredictable behavior
Down
  1. 1. A fault that is present and remains present
  2. 2. A loss event
  3. 4. A fault that occurs because of how the system was meant to be implemented
  4. 7. An approach to building systems where faults are designed to have a minimal impact
  5. 8. A type of fault that was not predicted, the cause of most system failures
  6. 9. This type of fault does not cause an error
  7. 10. This curve describes the failure rate of hardware over time
  8. 11. A state that could lead to unplanned loss of life, property, a release of energy, or a release of dangerous materials
  9. 13. A fault that occurs due to something breaking
  10. 15. A fault that is present but does not remain so
  11. 18. This type of fault causes an error
