Mass is a measure of inertia. The principle applies for innovations, especially around software products, too. Will-solve-world-hunger-idea that is too grandiose, complicated and resource consuming will take off far sluggishly than the one that is simple, easy to understand (preferably can be drawn without having to wipe the white board even once) and needs less resources (at least initially). Therein lies an important ingredient of turbo-charging the innovator’s probability of success.
An idea that has taken off will steadily gather momentum (yet another law of motion here) and will accelerate as sponsors see (and perhaps even feel) the initial outcome. The idea implementation will react with an equal (but not opposite) enthusiasm to the sponsor’s optimism.
