You will find an interesting article on complex systems here - and I would argue that T5 is a classic example of a complex system:

The key conclusion is here:
Bar-Yam thinks the loss of key people would be crucial. "Losing pieces indiscriminately from a highly complex system is very dangerous," he says. "One of the most profound results of complex systems research is that when systems are highly complex, individuals matter."
So build a highly complex operation like T5 with minimal staff relying on automation and individuals start to matter.
Now try and reconcile this with what we are told is an abusive management culture that does their level best to dis-empower their own staff.
