This approach to durability has two important implications. Initially, it indicates that sturdiness and dependability are carefully connected. A product that fails routinely is probably going to generally be scrapped previously than one that is a lot more reliable; repair service expenditures will probably be correspondingly larger, and the acquisition of a new product will glimpse that much more desirable. 2nd, this tactic suggests that longevity figures should be interpreted with treatment.
