While connecting say two systems of 99% reliability will be better than say connecting two systems of 50% reliability I don't think that's the real issue. I find the real issue is that there is no error propagation nor audit trail. Somebodys system notices a problem and does like `throw new IllegalStateException("Invalid Arg")` and good luck figuring out what happened. A lot of system/code aren't designed to be tested easily and they just accumulate bugs because nobody can fix them.
