摘要: The present work carried out the control of variability in biodiesel packaging through application steps DMAIC (Define Measure, Analyze, Improve and Control) Six Sigma quality program. method brings together a set statistical tools for study process variability. Prior to project, period evaluated between June October year 2017 average monthly variation loss was 387.7 liters with standard deviation 421.9 liters. After implementation improvements January March 2018, -3.187 60.95 This evolution reduction losses container possible actions involvement people billing shipping. all implemented, maintenance continuity controls met two important requirements program: customer focus financial impact.
