Garr Reynolds is a communications superstar. He has taken the art ( yes art) of presentation to Zen like levels. Thought his latest post might help a few of my clients to think more about the "Less is More" approach ( you know who you are!)
The Signal to Noise Ratio principle is borrowed from more technical fields such as radio communications and electronic communication in general, but the principle itself is applicable to design and communication problems in virtually any field. The authors sum up the signal-to-noise ratio this way:
The ratio of relevant to irrelevant information in a display. The highest possible signal-to-noise ratio is desirable in design.
"Every element in a design should be expressed to the extent necessary, but not beyond the extent necessary. Excess is noise."
Given that you are not Tom Peters - how "noisy are you presentations?".
