I agree with all of you that the main two point of design input is a market analysis or a customer needs/requirements. These two points are major for design input for industrial. However, from academia, it could be an idea or scientific research that trigger the input or the idea of the product. So I believe the source of design input could be different between the industrial point of view and academia. As industrial looking for a quick return from revenue-wise. you could think about design input as the foundation of the whole project.
