The institute’s report, To Err Is Human: Building a Safer Health System, found […]

Design of experiments (DOE) is a useful tool for determining specific factors affecting defect levels in a product. A major automotive company learned just how valuable this tool is when it conducted a study of defects occurring in its alternator product.
