The only issue I had was the common misconception that MTBF actually represents average life or average time to failure. For items with a long service life, that's not the case because of the impracticality of testing. But for items with a short life (sort of limited to consumables), it actually could be. For example, the service life of incandescent light bulbs, so there are probably computer-related parts in the same category. Things in development for a long time can also collect service life stats. OK, close enough. :-) | |
