Influence of Six Sigma DMAIC to Reduce Time Wasting of Line Supervisor in Production Manufacturing

摘要

The Fast-growing global competition faced by organization forced different manufacturing industries to develop various process improvement approaches to respond efficiently to the challenges such as lead-time. Six-sigma DMAIC (Define, Measure, Analyze, Improve and Control) approach is an example in this part of manufacturing strategies. This paper aims to prove the practical application of Six Sigma DMAIC to reduce time wasting of line supervisor in Aluminum car parts manufacturer. The study used statistical tools and technique to identify the problem, find the root-cause of variation, reduce the time wasting, and provide solution. The analysis of planned and actual work tasks of the line supervisor revealed the time wastage of 49% called gap or breach. During different phases of this study, improvements implemented reduced time wasted from 49% to 16.3%. Pareto chart shows that the Line supervisor wasted more time in meetings followed by scanning.
