It’s been quite a few weeks for bunglers.
First, Peter Hain "forgot" to declare more than £100,000 of donations to his deputy Labour leadership bid.
Then Rudy Giuliani concocted the biggest foul-up in American political history by saving all his guns for the Florida primary… and then limping in third. As Kevin Connoly put it in his terrific analysis on the BBC:
"We always knew that Mr Giuliani’s strategy of focusing his time, energy and money in the first big state to vote was one of two things; either a stroke of political genius that would rewrite the rule book about how you run for the presidency, or an act of madness that would see the long-time Republican front-runner fall at the first hurdle.
"Now we know which it was".
With these tales of woe in mind, here’s a reminder of how to spot incompetence in your own business. Beware, this is not comfortable reading.
