| dc.description.abstract | This thesis focuses on the application of the DMAIC (Define, Measure, Analyze, Improve,
Control) methodology in reducing defects and improving quality in the assembly process
of Scancom Vietnam. The study utilizes data collected from September 2022 to March
2023, which revealed that the defect rate exceeded the acceptable limit of 1% for five
months during this period. To address this issue, a thorough analysis was conducted,
starting with the Pareto chart of failed components. The findings indicated that three main
defect types required focused attention: Cracked (195 occurrences), Dented (74
occurrences), and Discoloration (45 occurrences). To understand the root causes of these
defects, data on defect rate, failed components, and rework costs for the three defect types
were collected and analyzed. Having identified the problem and root causes, the project
aimed to find the most optimal solutions based on their effectiveness, implementation timeframe, and required human resources. The proposed solutions were reviewed and assessed
by the process manager to determine the estimated results. As a result of the implemented
measures, a reduction in defect rates for the three defect types was achieved: Cracked
(0.36% to 0.29%), Dented (0.14% to 0.11%), and Discoloration (0.08% to 0.05%).
Additionally, the thesis made suggestions for how to keep the enhanced process under
control once it has been formally implemented in wood production. | en_US |
