Think Bigger: How to Innovate by Sheena Iyengar, provides a framework for creative problem-solving, drawing on real-life examples and research to help readers develop innovative ideas. The book breaks down the innovation process into six steps: choosing the right problem, breaking it down, comparing wants, searching in and out of the box, Choice Mapping, and the Third Eye Test. The author emphasizes that innovation is not about coming up with completely new ideas, but rather about combining existing elements in a novel and useful way. The text explores various concepts including root cause analysis, the importance of curiosity, and the role of emotions in decision-making.
