Gerry Pennell was CIO of the 2012 Olympic Games in London.
A strong emphasis on process and role clarity also contributed to everyone being ready as soon as the Games got going, he said.
However, Pennell said the thing that was most important to success was shared commitment to a common goal of delivering a great Olympic Games.
"It was really that motivation that enabled my team and the rest of the organising committee and the teams of our respective partners all to overcome the various barriers that we encountered [and] to deliver in the end."
