A software, hardware and marketing manager are driving to a meeting when a tyre bursts. They get out of the car to look at the problem.

The software manager says, “I can’t do anything about this. It’s a hardware problem.”

The hardware manager says, “If we turned the car off and on again, it might fix itself.”

The marketing manager says, “Hey, do you know what? Over 70 per cent of it is working. Let’s ship it!”
