Where can a hospital apply principles from the airline sector? How can a car manufacturer use tools from the video game industry? What can an event organiser learn from the railways? Cross-industry innovation is a clever way to jump-start your innovation efforts by drawing analogies and transferring approaches between contexts, beyond the borders of your own industry, sector, area or domain. Not invented here refers to the phenomenon of people blocking out ideas from the outside, it also indicates that there are beautiful alternatives everywhere just waiting to be introduced to your context. The potential of ideas and approaches from other areas is tremendous, still only very few organisations apply cross-industry innovation strategies in any kind of structured way. The book Not Invented Here provides you with cross-industry innovation strategies and tools to increase your match sensitivity' (the ability to make more effective connections) and see the opportunities available to you. With the chapters The art of questioning, Someone else has solved your problem, Inspiring industries & smart sectors, Your business challenges and many more this book opens up interesting new perspectives and is a significant source of major innovative steps. This inspirational, illustrated business book presents strategies & tools for cross-industry innovation.
