Use of the dmaic tool: high failure rate in the heat sink bolting process

The DMAIC methodology has the potential to detect flaws in production processes and point out improvements for the results. In this sense, the general objective of this research seeks to point out through a case study how the use of DMAIC within a company in the manufacturing sector of other assorted electrical equipment and components, evaluating the high failure rate in the heat sink screwing process, can be an effective tool to leverage and improve the company's production processes, thus resulting in greater profitability. Thus, the specific objectives seek to present and conceptualize what is quality management, conceptualize what is production management and how the application of its primary principles result in advantages for an effective production management, elucidate what and how a process mapping occurs in accordance with the process engineering, To present and conceptualize what the continuous improvement of processes is and what its main tools are, to conceptualize what the DMAIC methodology is, and finally, to conduct a case study in a company that produces and supplies automotive parts, pointing out how the use of DMAIC can be a great differential, in order to reduce failures in production processes and leverage profitability. In order to reach the objectives, bibliographical research was carried out to survey the theoretical basis and, subsequently, a case study was applied in Company X. Finally, it is suggested that a new case study be conducted, where the DMAIC methodology can be applied again, in order to demonstrate its effectiveness in manufacturing companies.
