摘要:The purpose of the proposed text is to analyze the implementation of different methods from lean production and other quality methods at the shop floor of three companies of household appliances in Brazil. The research involved interviews with managers and supervisors of production, quality, and human resources department and also with shop floor workers from different production areas, in order to find out the operations management methods adopted and the workers’ involvement in their use. Many methods related to lean production foresaw the involvement of workers or even that they would be the primarily responsible for their use. However, practices adopted more recently, such as Six Sigma, don’t have the same emphasis to employees involvement compared to practices adopted in previous decades. The proposed text will examine how this issue has evolved in literature and at the companies surveyed, exploring also some potential explanations for the observed limitations.
