design

design, plan or arrangement of line, form, mass, color, and space in a pattern. A design may be created to serve a functional purpose as in architecture and in industrial designs or else purely to provide aesthetic pleasure. The design may refer to preparatory stages for a work of art (see drawing; cartoon) or it may be extended to include the compositional elements in a finished work of art.

(process)

design - The approach that engineering (and some other) disciplines use to specify how to create or do something. A successful design must satisfies a (perhaps informal) functional specification (do what it was designed to do); conforms to the limitations of the target medium (it is possible to implement); meets implicit or explicit requirements on performance and resource usage (it is efficient enough). A design may also have to satisfy restrictions on the design process itself, such as its length or cost, or the tools available for doing the design. In the software life-cycle, design follows requirements analysis and is followed by implementation. ["Object-Oriented Analysis and Design with Applications", 2nd ed., Grady Booch].
