Analyzing the Short-term and Long-term Sigma Level Relation in a Metal Fabrication Process 1: Universidad Autónoma de Ciudad Juárez, México; 2: Universidad Tecnológica de Ciudad Juárez, México; 3: Universidad Autónoma de Ciudad Juárez, México This study analyzes the relationship between short- and long-term sigma levels in a metal bottle manufacturing process using an approach based on the Six Sigma methodology. Although in the 1990s, Mikel Harry established an average difference of 1.5 sigma between these two metrics, the present work questions the validity of this value, considering technological advances and the evolution of industrial processes. A six-stage methodological design was employed, including identifying a critical response variable, collecting 800 data points by controlled sampling, and statistical analysis to determine short- and long-term sigma levels. The results show that for this process, the short-term sigma level is 1.455, while the long-term level is 0.423, generating a ratio of 1.023. This suggests that the gap established by Harry does not apply universally. The results conclude that updating the metrics used in Six Sigma projects is necessary to improve decision-making accuracy, opening new opportunities to investigate this relationship in other industrial sectors. | |
