Dieter Rams is one of the most influential product designers of the twentieth century. Even if you don''t immediately recognize his name, you have almost certainly used one of the radios, clocks, lighters, juicers, shelves or hundreds of other products he designed. He is famous not only for this vast array of well-formed products, but for his remarkably prescient ideas about the correct function of design in the messy, out-of-control world we inhabit today. These ideas are summed up in his ''ten principles'' of good design: good design is innovative, useful, and aesthetic. Good design makes a product easily understood. Good design is unobtrusive, honest, durable, thorough, and concerned with the environment. Most of all, good design is as little design as possible.
