A seven-point plan showing why the London 2012 Games ran smoothly has been published.
The idea behind the Government-commissioned report - Making the Games - is that Whitehall needs to learn from its successes as well as its failures.
Given Britain's track record for failure on high-profile large-scale projects - such as the Millennium Dome, Wembley Stadium and the bid for the 2015 World Athletics Championships - many had reason to believe that London 2012 would be the same.
Sceptics immediately had to be won over as the starting point for London 2012 was the failed bids in the previous decade by Manchester and Birmingham to host the Games.
There was also the "unfeasibly low budget at the time for the bid which augured poorly for the finances of the Games", the Institute for Government report stated.
