Profits were up due to cost-cutting all over the place. ROCE is poor, and profits are almost irrelivant when ROCE is poor. T5 was a mess. He isn't paid to mess up things like that. Sure you can say "he has learned" etc, but a person in his position shouldn't screw it up in the first place!
It is fine to learn your lessons when in lower management but in his position he should be smart and wise enough NOT to make mistakes. T5 was a disaster waiting to happen and staff were telling him. Completely useless.
