Design means different things to different people. A clothing manufacturer believes that incorporating different materials or colors into a new dress constitutes design. A potter paints designs onto china to complement its surroundings. An architect designs ornamental facades for residences. An engineer chooses a bearing from a catalog and incorporates it into a speed-reducer assembly. These design activities, although they appear to be fundamentally different, share a common thread: they all require significant creativity, practice, and vision to be done well.
