Lean Six-Sigma Approach for Sub-Contract Licensing and its Process Improvement across the Manufacturing Supply Chain using GUT Priority Matrix

This study aims to examine how Lean Six Sigma as a quality management tool could enhance productivity in a manufacturing organization, ZITRON. In addition, this study also aims to show how DMAIC (defined, measured, analyzed, improved and controlled) is operationalized for overall process improvement in ZITRON manufacturing. Lean management takes care of waste across all processes and focuses on speed and time within a firm while Six Sigma is a strategy that focuses on eliminating defects, reducing costs and also reduces process variability. As such, this study utilizes the Lean Six-Sigma approach as a tool to ensure more efficiency is achieved in terms of source, make, delivery and process efficiency. Methodologically, there are five phases in the Lean Six Sigma strategies which are defined, measured, analyze, improve and controlled (DMAIC). The findings show that Lean Six Sigma can help to eliminate waste, and cost-reduction, and help eliminate variations in processes within the manufacturing. However, SIX SIGMA tools have been used to solve the problem which is a delay in processes in manufacturing. Based on this research paper, focuses on the manufacturing problem which is a delay in processes. By using Six Sigma, the problem that existed in manufacturing has been solved through process improvement. This work is originally following a self-method in which the data is collected by using observation techniques to identify the existing problem and solution-seeking within the manufacturing.
