And when we look at this report that has been done, I was so, so sad reading this, because I know how hard people in our health workforce are working. No one there wants to make mistakes. No one wanted to be the person who realised that the call wasn't made because of the technology. Those are horrible, horrible reasons and horrible things to deal with in your work. What struck me, though, in both these cases is it was not just one thing that happened; it was a succession of things that went wrong. Things escalated, and in some cases the escalation that should have happened never did.
