According to MIRP researchers, innovation process has three main periods: invention, development, and implementation. 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 elaboration of the idea takes place at the development stage. After identifying a customer problem worth solving, innovators search broadly for a variety of solutions and then use a series of prototypes. A prototype is a full-scale working model that is being tested for design, function, and reliability. Implementation means the widespread acceptance of the innovation. The central mechanism of implementation is exploitation, which contains such things as refinement, choice, production, efficiency, selection, and execution. The correct answer is Choice D.
