Invention refers to the emergence of an idea. The key mechanism of invention is exploration, which includes things represented by words such as search, variation, risk-taking, experimentation, play, flexibility, and discovery. Invention includes generating an insight about the customers’ problem or need and profoundly understanding this problem or need. The insight could be finding a problem that others have missed or perhaps uncovering a potential new solution to a well-understood problem. Four behaviors trigger generating insights: questioning, observing, networking, and experimenting. The correct answer is Choice E.
