Quality
“Good design is thorough to the last detail. Thoroughness and accuracy of design are synonymous with the product and its functions, as seen through the eyes of the user.” – Dieter Rams
“When you’re a carpenter making a beautiful chest of drawers, you’re not going to use a piece of plywood on the back, even though it faces the wall and nobody will ever see it. You’ll know it’s there, so you’re going to use a beautiful piece of wood in the back. For you to sleep well at night, the aesthetic, the quality, has to be carried all the way through.” – Steve Jobs
