This document discusses the principles and methods of robust design. It defines robustness as a product or process being minimally affected by sources of variation. Taguchi methods are presented for designing products and processes that are robust, including parameter design to optimize the signal-to-noise ratio. An example applies Taguchi methods to the design of a Nerf missile to maximize firing distance while minimizing the impact of noise factors like user skill level. The results of the experiment are analyzed using Minitab to identify the optimal settings for the design parameters to achieve the most robust performance.
