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.'
