Functionality is a key component of design. My favorite example of a design disaster was Steve Harvey’s now famous crowning of the wrong Miss Universe. Every visual designer knows that english speakers read information from left to right, and from top to bottom. This a rule that guides the composition of everything from magazine covers to gas pumps. Poor Miss Columbia suffered at the hand of a poorly designed note card, which put her name immediately to the left the Miss Universe Title, and the name of the real Miss Universe on the bottom right of the card - just under Steve Harveys thumb. Design is not how something looks, but how it works. Important details should always be designed with care, no matter how large or small the project.
