[All CPIM-Part-2 Questions]

Which of the following statements is true about the mean time between failures (MTBF) measure?

Show Suggested Answer Hide Answer
Suggested Answer: C

Mean time between failures (MTBF) is the predicted elapsed time between inherent failures of a mechanical or electronic system during normal system operation1.MTBF can be calculated as the arithmetic mean (average) time between failures of a system1. MTBF is a useful measure of reliability, because it indicates how long a system is likely to work before failing.The higher the MTBF, the more reliable the system2.Reliability is the probability that a system will perform its intended function without failure for a specified period of time under specified conditions3.

The other statements about MTBF are false. MTBF is not used for non-repairable products, but for repairable systems.For non-repairable products, mean time to failure (MTTF) is used instead4.MTTF is the expected time to failure for a non-repairable system1.An increase in MTBF is not proportional to an increase in quality, because quality is not only determined by reliability, but also by other factors such as performance, functionality, durability, and customer satisfaction5.MTBF is not the same as operating life or service life, because operating life or service life is the total time that a system can operate before it reaches the end of its useful life, while MTBF is the average time between failures during the operating life6.

Hmm, that makes sense too. I can see why that would be important in assessing product reliability.

I think I'll just go with C. It sounds the most reasonable, and I don't want to overthink this.

Haha, I bet the engineers who came up with MTBF were real fun at parties. 'Hey, wanna hear about our latest reliability metric?'

Hmm, I'm not sure. Is MTBF really used for non-repairable products? That sounds a bit off to me.

D is the answer. MTBF is the same as operating life or service life, which is the average time a product will function before it needs to be replaced.

B seems right to me. If the MTBF increases, it means the product's quality has improved, right?

I think the correct answer is C. MTBF is a useful measure of reliability, as it tells us how long a product is expected to function before it fails.
