Principles were differentiated from rules such as those for the placement of type. Whilst contributing to the design process, rules are not principles. The parts embarrass the whole. Once concept is understood, no design or content feature will be included which does not fit it. Design the whole before the part.
Design comes in two stages, concept and parameters, and detail in execution.
Design once, devise, design again User first, user last. If a map were a building it shouldn t fall over 2. Lesser things have their place and should serve to complement the important. From the whole to the part, and all the parts, contributing to the whole. Associated items must have associated treatment Harmony is to do with the whole map being happy with itself.
