Dieter Rams is a German industrial designer who was responsible for the design of Braun’s consumer products for many years and one of the most influential industrial designers of the last 50 years. He held a firm belief that good design can only come from understanding people. In the 1980’s, Rams set out to create an overview of what defines good design. As good design cannot be measured in a finite way, he set about expressing the ten most important principles for what he considered was good design. Sometimes they are referred as the “Ten commandments”.The beauty of these principles lies partly in the uniqueness of their composition, but also in the fact that they apply just as much to digital design as they do to industrial design. It’s amazing to see how valid these principles are today even more than back then, when Rams actually wrote them!Below links will provide you more details about “Dieter Rams’ 10 Timeless Commandments for Good Design”.
