This question is nuanced, as your contribution in the context of this question is just as important as how you offered it. How you answer this question could inform your interviewer of your work style and ethic. Start by detailing how you identified an opportunity, how you pitched it, the support or lack of support you received, and the success you found as a result of your efforts.

You want the answer you offer to center around their leadership principle, 'Invent and Simplify,' where they state, "Leaders expect and require innovation and invention from their teams and always find ways to simplify. They are externally aware, look for new ideas from everywhere, and are not limited by 'not invented here.' As we do new things, we accept that we may be misunderstood for long periods of time." Consider their leadership principles, 'Think Big' and 'Frugality,' as well. The more principles you can embrace in each answer, the better.
