During new product development, decisions that are made throughout concept development and design have significant impact on a product’s success in the market.  Customer needs, design engineering problems and corresponding design requirements are not fully known at the beginning of a project.  This presentation will describe a method of exploring multiple, simultaneous requirements and design options for as long as possible to allow for the most desirable design choices to be made over time. Using set based method for design problem solving is the “wheel house’ of talented design engineers and innovators.
