Taguchi methods are a set of statistical methods developed by Genichi Taguchi for improving the quality of manufactured goods and for research and development. The primary goal of Taguchi methods is to improve product quality by making the product design robust to variations in manufacturing processes and environmental conditions. This robustness is achieved by minimizing the sensitivity of the product's performance to these factors, which are often referred to as "noise factors."

A core concept in Taguchi methods is the use of orthogonal arrays. These are experimental designs that allow for the efficient study of multiple factors with a minimum number of experimental runs. Orthogonal arrays ensure that each factor is studied independently of the others, allowing for the identification of the most influential factors. The methods also emphasize the use of a signal-to-noise (S/N) ratio to evaluate the performance of a product or process. A higher S/N ratio indicates better performance and robustness.

Taguchi methods aim to reduce costs by improving quality, leading to fewer defects, less rework, and increased customer satisfaction. The approach focuses on designing quality into the product from the outset, rather than relying on inspection to detect defects later. This proactive approach is a key differentiator from traditional quality control methods. The philosophy promotes engineering solutions that are inherently reliable and insensitive to variations, thereby achieving high quality at a lower cost.
