This study aims to use DMAIC approach as one of the methods in order to achieve the target which is improve the quality in manufacturing industry. The example of method that use in every phase also will be explain in details. The case study was conducted at a rice production industry located in Perlis. Based on data collection and discussions with employees, the industry has problems in terms of rice quality defects. The method that has been used in the define and measure phase were problem identification, data collection, process flow chart, process mapping and cause effect diagram. It was found there are three defects regarding the quality of product in the production. The throughout analysis conducted by using methods such as fishbone diagram, 5 Why analysis and failure mode and effect analysis in order to identify the factor and root cause of the problem. In improve phase, two methods such as technical training checklist and poka yoke were suggested to improve the quality of product. Finally, control plan check sheet was suggested as the guarantee to control the improve process.
