Interdependency

...or "When the surgeon makes a mistake it's the patient who dies".

It's like: You're the captain of a fishing boat and while you're in your quarters doing paperwork you're pondering what kind of catch this day will bring
...only to find out, when you return to deck, that your dimwitted crew members forgot to cast the net into the water, hence you've just wasted four hours at sea and it's now time to return to port.
