Robust Design and Process


Overview/Description
The goal of robust design is to provide a more efficient, cost-effective means of improving a product or process. Designed to ensure consistent, high-level performance in line with strict customer requirements, the robust design methodology relies on an organized framework of experimentation and analysis to develop a product or process. This approach to engineering and design results in reduced product and process variability, so that the product or process under development is minimally impacted by use-conditions and other uncontrollable factors. By deploying a variety of strategies to reduce sensitivity to the noise factors that degrade performance, it also ensures maximum robustness. In this way, robust design facilitates the development of products and processes that achieve the required level of performance at the minimum expenditure, in the shortest timeframe, and under a wide range of use-conditions.
