The implementation of Lean Six Sigma approach to minimize waste at a food manufacturing industry

Abstract

Lean Six Sigma is an integrated approach between lean thinking and the Six Sigma method. Lean is a way of thinking and principle used to improve the performance of a process through waste and error elimination. It focuses on the speed, flow, and cost of a process. On the other hand, Six Sigma is a method to enhance process capability by analyzing processes with problem identification and implementing improvements to resolve the problem. It focuses on quality consistency and how to fulfill customers' requirements. Combined, Lean and Six Sigma will be beneficial for organizations in determining the most suitable method for identifying and solving problems so the outcome of a process can fulfill customer satisfaction until profits can be increased. This study proposes a Lean Six Sigma methodology as an approach to reduce waste in the production process of a food manufacturing industry. The proposed approach is the DMAIC approach, and its tools are used to assess the impact of waste on the production process. As a result, this study will also conclude how the DMAIC approach can be helpful for the company to reduce waste. Suggestions related to DMAIC tools, and their implementation are also elaborated so that the related company can evaluate its current process and strive for better improvement.
