Simply Marvellous

The process of rationalisation and simplification is analogous to the perceptual process of filtering, and its principle benefit is to eliminate the need for perceptual filtering. By filling in those patterns that have been developed, and eliminating those details that don't support the developed patterns, the rationalisation process makes a design more approachable, more comprehensible and more predictable.

One of the most common uses of rationalisation and simplification is to provide an overview, or a key to a complex design. This schematic allows the user to explore the design checking every idea against the schematic to find those areas that extend and consolidate the basic idea of the design.
