Re: I always laugh when companies use the phrases
If it really were all, the problem would be detected almost immediately. many resources would be directed to fixing it, and it would probably be easy to diagnose.
"Some" is worse, because it reduces the organization's incentive to find and fix the problem, and the more conditions that apply to the failure case, the harder it is to isolate the cause. In terms of general categories, inconsistency is probably the biggest issue with software.
