Innovation: Positive, Incremental Change with the potential to lead to something completely new.
Revolution: Sudden, Dramatic Change that is typically a painful, confusing, and expensive route to an unpredictable outcome.
Innovation and Revolution can have the same objective and may arrive at the same place. The differences between them can be measured in terms of Time and Control on the one hand and Cost and Benefit on the other.
Channeling Innovation: A process that directs Innovation towards a predefined goal, avoiding many costs and retaining control along the way.
