The table napkin test - Cognitive Edge - 1 views

One of the golden rules of sense-making is that any framework or model that can’t be drawn on a table napkin from memory has little utility. The reason for this is pretty clear, if people can use something without the need for prompts or guides then there are more likely to use it and as importantly adapt it. Models with multiple aspects, more than five aspects (its a memory limit guys live with it) or which require esoteric knowledge are inherently dependency models.
