A man is flying in a hot air balloon and realizes he is lost. He reduces
height and spots a man down below. He lowers the balloon further and
shouts,
‘Excuse me, can you help me?
I promised my friend I would meet him half an hour ago, but I don’t know
where I am.’
The man below says,
‘Yes. You are in a hot air balloon, hovering approximately 30 feet above
this field. You are between 40 and 42 degrees North latitude, and between
58 and 60 degrees West Longitude.’
‘You must be a programmer,’ says the balloonist.
‘I am,’ replies the man.
‘How did you know?’
‘Well,’ says the balloonist, ‘everything you have told me is technically
correct, but I have no idea what to make of your Information and the fact
is I am still lost.’
The man below says, “You must be a project manager.”
‘I am,’ replies the balloonist, ‘but how did you know?’
‘Well,’ says the man, ‘you don’t know where you are, or where you are
going.You have made a promise which you have no idea how to keep, and you
expect me to solve your problem.’
