Will Evans discusses the challenge that companies face in creating products customers actually want, reducing cost, and eliminating waste in the process. The lean thinker does this in part through experimentation.Teams practicing LeanUX inside of organizations embracing Agile have developed a set of principles and methods for experimentation based on collaboration, customer research, problem space exploration, set-based design of solution hypotheses, and tight feedback loops. These approaches increase the optionality in the product development pipeline while mitigating risk. These principles and methods in experimental design based on the scientific method don't come naturally, but they are very useful and valuable if you are interested in increasing organizational learning, reducing risk, and delivering real value to customers.
