There was never enough time to do it right from the beginning for the customer, but there was always time enough to spend hours on end fixing it or redoing it.
And what about spending months waiting for the customer to decide he really needs some piece of software only to discover that when he finally give the start on the project it should really have been ready yesterday :w00t: ?
But you normally can't say to a customer of yours that bad planning on his part does not translate in emergency on your part...
