DMAIC SIX SIGMA APPROACH IN GOLD SCRAP/WASTE MANAGEMENT PROCEDURE FOR SMES JEWELLERY INDUSTRY

Abstract

This study uses mixed methods to collect data from a jewellery manufacturer to address the issue of gold losses during manufacturing. The research used the DMAIC technique (Define, Measure, Evaluate, Improve, and Control) to analyse and uncover root causes of gold losses, improve gold scrap collection operations, and reduce the amount of gold that has gone missing. The data was gathered through a survey and observations, all based on the theoretical framework. As a result, there are five root causes of gold losses, classified into six categories and a graphic of the impacts. The study was narrowed down to only five categories, which are as follows: methods, people, measurements, materials, and equipment are all important considerations. The researcher provided five options to address the underlying cause problem and a few control strategies for measuring and maintaining progress. This research has benefited the company in several ways. The Standard Operation Procedures (SOPs) of gold scrap management techniques have been produced to reference for scrap reduction in the jewellery making sector to control and sustain the process.
