That makes sense, but the point is that it's still a compromise. Even if we're saying that people can work overtime to get things done, there's typically diminishing returns on each additional hour worked, and still no guarantee that quality hasn't been impacted.

If you ask people to work 12 hour days instead of 8 days, does each day provide 8 hours worth of work, 12 hours worth of work, or another value? Can we reliably say that any problems arising from working over 12 hour days are caught and handled at the same level as they would be if people were working 8 hour days?
