Estudo da metodologia Seis Sigma através da ferramenta DMAIC: projeto piloto de implantação em uma indústria cimenteira

Abstract

The pursuit of excellence in processes, delivery of high quality products and services and meeting customer requirements is only possible if organizations use methods and tools that aim to continuously improve the quality and standardization of all stages of their production processes or service provision. The Six Sigma methodology introduced in the manufacturing sector by Motorola in the 1980s brings a new approach to the use of quality management tools to improve customer satisfaction, reduce costs and continually improve processes. The present study is characterized as a mixed research, since it will be based on quantitative and qualitative data to base its conclusions, having as main tool of approach the data collection. The data will be collected through software, Excel spreadsheets and interviews in a cement factory located in the Gaucho Region. Informal interviews, surveys and analysis of causes of bottlenecks were carried out in the process of loading the main product produced by the factory, responsible for the area of logistics, with the help of quality tools to carry out each DMAIC stage. It is concluded that the main impacts in the increase of the customer service time come from the loading and queuing process occur in the same place on days of meteorological instability, the causes were raised and the suggestions for improvements presented, but for improvement of the process is investment by the organization. Therefore, the steps for the design and implementation of the Six Sigma methodology have been completed. As a suggestion for future research, studies on clinker addition processes in the area of cement milling and analysis and survey of problems in the bagging area, specifically in the bag weighing activity after the bagging process of the cement to verify the bags with weight variability beyond that established.
