This study refers to the importance of production management, where knowing the processes in depth is an essential feature for the reduction of waste. The work was motivated by the following problem: How can the establishment of a manufacturing cell with a cellular layout help to increase productivity? The objective of the study was to propose the implantation of a manufacturing cell that meets the needs of productive increase and elimination of waste. The value stream mapping was used to understand the current process and simulation of the future process, while the Yamazumi graphical tool was used in the analysis of the distribution of operations, and the spaghetti diagram was used to compare the current layout with the proposed one. Through the establishment of a manufacturing cell, a reduction in production time of 8 days was projected, with a potential gain in production time of 27.58%, making it possible to produce 3 more pieces a day, in addition to an improvement in the inventory turnover of 37.63% and a reduction of 3 people involved in manufacturing. The present study showed a decrease in waste of 20%, and optimization of the activities that add value throughout the productive chain.

This paper proposes the use of QFD for the continuous improvement of production processes and waste reduction actions. To collect the information we used the simple observation and questionnaire with closed questions applied to employees, representing 88.75% of the population that works in the production processes of an industry of metal-mechanic sector, located inRio Grandedo Sul. QFD is an effective method of quality planning, because it provides a diagnosis that underpins the definition of improvement actions aimed at combating waste. Actions were set providing improved communication between the sectors, enabling the delivery of products with specifications that meet customer requirements, on time and the right amounts, at a minimum cost and satisfaction of those involved with the company. The implementation of these actions reduces waste, minimizes the extra work, maximizes effective labor and increases profitability.
