RESUMO

The advent of microelectronics and of the transmission of information has created a greater integration between the development of the product and the fabrication process in the sector of forge. Besides, the orientation of this sector, especially in the branch of the auto parts, caused us to think, as Taylor and Ford had already done at their time, about the way whereby the organization of labor should be done in the forges to assure quality and competitiveness. However, the challenge is different today, mainly as regards the human resource. Our proposal of the model for a product and process integrated system with continuous improvement of the quality arose from this thought and brings some propositions that we could develop. Since 1990, with the lifting of the economy barriers, the forge, in the Brazil, began to face changes and challenges on top of which there was the factor of the reduced import taxes. This brought about the importation of products at worldwide quality and price levels, thus influencing the profile of the consumer market, which became more demanding in face of the international parameters. The Brazilian forges faced a strong competition mainly from India, Turkey and China with reference to price, and from Japan, Germany and United States with reference to technology on top of price. In this industrial and commercial environment, in which competitiveness is the essential facto r for the survival of the Brazilian forges - because it demands quality and low cost - a model of continuous improvement of the quality became necessary. The core point of this model is the change in the management that, as we have seen, has historically been present as the essential factor in the development of the industry. To face this challenge, our model proposes a closer integration between the project of the product and that of the processo By means of training, we have searched to qualify the employees to interact with the constant process of organization change. They should also be prepared to absorb new technologies and to. be able to implement the process of continuous improvement. The central point of this work consists in the development of a quality model in a forge of the auto parts sector. We started from the principie that the most important factor in the operation of a forge is the knowledge of systems that interrelate themselves with the variables and the parameters of the quality leveI. Through the analysis of these systems, conditions may be established for a model adequate for a world class manufacturer and at the same time looking forward, to the satisfaction of the customer. The quality model proposed was developed through the research, analysis and development of three systems: business process, quality system (QS) and continuous improvement. The study of these processes was based on the theory of the general system. Taking into consideration the business process and the quality system of the forge, we developed the FQS (Forge Quality System) and the initial IQM (Initial Quality Model). The implementation of the IQM revealed that the results of the quality level, when compared to previous quality system of the forge, presented better performance, even if not to the full expectation of the values that are present in the state-of-the-art forges. Observing the IQM and considering the continuous improvement system, we developed the QM (Quality Model) of the forge. The analysis of the implementation of the QM was made through the indicator of quality, the cost of quality, the assessment of the customer satisfaction and the evolution of the model with base on the theory of the general system. The results obtained with this implementation were then compared with the values that existed before in the forge and the outcome was an improvement of the level of quality compatible with that of forges in the developed countries
