The analysis of test result stability is an essential methodology to ensure that a test system continues to deliver reliable, repetitive, and consistent measurements over time. This practice is fundamental to maintaining the reliability of the production process and avoiding false failure diagnoses. 🧪 Why is result stability so important?
In production testing, validation, and quality control, correctly defining the tolerance limits is one of the most critical factors to ensure reliability, repeatability, and yield (FPY). The test tolerance represents the acceptable margin of variation between the measured value and the expected nominal value, taking into account natural imperfections of
Six Sigma is a quality management methodology focused on reducing defects, variability, and waste in industrial and organizational processes. Its goal is to achieve an extremely high level of performance, where processes generate a maximum of 3.4 defects per million opportunities (DPMO). Origin and Fundamentals Created at Motorola in the
