Scale is another way of asking an idea about the future.
Design firms test the scalability of a logo idea by reviewing it at different sizes, in different colors and in different media conditions. Does the idea translate consistently from a print ad, to the side of a building to a 16 pixel-square favicon? Does the logo idea scale across different languages and cultures?
Food manufacturers test the scalability of a new product idea in terms of a formula: manufacturing, marketing and distribution costs versus the size and appetite of an addressable audience.
In the short term, politicians measure the scalability of their ideas with polls and fundraising. History takes care of the rest.
Writers test the scale of their book ideas with blogging.
Web engineers might test the scalability of an idea by estimating server traffic. (Side note: Fascinating article here on Tumblr’s astounding technical growth related to serving 15 billion page views per month.)
So the question, “Will your idea scale?” has little to do with the present moment. Nor is it about revelation or intended insight. Rather, “Will your idea scale?” is an exploration of an idea’s flexibility, its resilience and the cost to sustain it over time. It is a question of potential.
