Question
What is the difference between a system whose reliability prediction is MTTF versus one whose reliability prediction is MTBF?
Options
- AThere is no difference. Both terms mean essentially the same.
- BMTTF implies that the system can't be repaired. MTBF implies that it can be.
- CMTBF implies that the system can't be repaired. MTTF implies that it can be.
- DMTTF is used for maintainability studies. MTBF is used for reliability studies.
