Lean manufacturing and Six Sigma based on Brazilian model “PNQ”

Abstract

Purpose – This paper aims to show the main results of an implementation of a tool developed to assess the integrated elements originated from lean manufacturing and Six Sigma, based on Programa Nacional da Qualidade – Brazilian National Quality Program (PNQ). Design/methodology/approach – This is an applied and qualitative research, which used basic qualitative studies and descriptive techniques as research strategies. A five-point Likert scale was used for the evaluation of the elements and constructs. The instrument was applied in one manufacturing company located in the Southern region of Brazil. Findings – The application of the instrument showed that the use of an instrument like that can be useful in the management of elements and constructs of companies that have the lean manufacturing and Six Sigma implemented. In the case of this company, among the nine constructs, three of them need more attention: strategy, culture and customer. Research limitations/implications – Because it is a research by means of a case study, the results cannot be generalized and should be applied in other organizations. Thus, their results could be further explored and discussed. Practical implications – The results point out relevant aspects related to the evaluation of integrated elements of Lean Sigma and the importance of a tool to manage them in order to reduce costs and others resources. Originality/value – As the application of Lean Sigma is relatively recent and there are little data published about its utilization in a developing country, it is important to expand knowledge on this subject.
