Negative Requirements

Nothing is funnier than requirements which state things that are not to happen.

An actual quote.

... don't screw up cutting and pasting and the "/" vs "\" depending on unix / windows.

Why not list everything that's not supposed to happen?

• No fire in the server room.
• No anthrax outbreak.
• No Zombie apocalypse.

The list could go on. I wonder why it doesn't.
