Resumo

The Six-Sigma program is an approach currently adopted by many companies and its usage occurs through a highly disciplined and guided process, inResumo O programa Seis Sigma é uma iniciativa adotada atualmente por muitas empresas e seu uso ocorre por meio de um processo altamente disciplinado e orientado, no qual são aplicadas diversas técnicas e ferramentas, que objetivam a geração de um ciclo de melhoria contínua. Diante desse fato e considerando a relevância do assunto, foi conduzido um levantamento tipo survey com o intuito de identificar e analisar as técnicas e ferramentas usadas nas etapas do método DMAIC e a sua comparação com a prescrição da literatura. Buscou-se levantar as técnicas e ferramentas mais e menos empregadas pelas empresas, permitindo-se confrontar estes resultados com outros levantamentos já realizados no exterior. Cabe destacar também que os resultados confirmaram o indicado pela literatura, os quais apontam que o programa Seis Sigma necessita apoiar-se em dados mensuráveis e confiáveis, evidenciando assim que o emprego das técnicas e ferramentas é indispensável junto ao método de melhoria DMAIC.

Purpose -The utilisation of Six Sigma and its associated techniques has yielded results that deserve a more detailed evaluation, since there is relatively little information published on the application of Six Sigma in developing countries. The objective of this work is to present the results of an exploratory-descriptive field study, which was done to survey a series of practices related to Six Sigma programmes at companies that have adopted them. Design/methodology/approach -The paper presents a descriptive survey. More than 100 Six Sigma users were identified and contacted by telephone to respond a questionnaire. Two remembering letters were sent to companies that did not answer the survey resulting in a response rate of approximately 65 per cent, which can be considered suitable by the literature for a descriptive survey. Findings -The results obtained from the survey revealed that the application of Six Sigma in Brazil is a reality. However, it concluded that the programme was adopted by large-size companies that invest in infrastructure and training of their personnel, making it possible to obtain the financial benefits desired. Research limitations/implications -This is not a probabilistic study and, therefore, the external validity is limited. The paper also considers perspectives for future research on the use of techniques and tools associated to the application of the programme as well as factors of failure in its utilisation. Originality/value -This paper is one of the few published studies that report and discuss Six Sigma programmes in developing countries.

PurposeSix Sigma program is an approach currently adopted by many companies, which involves a highly disciplined and guided process, in which applications of many different tools and techniques aim at generating a cycle of continuous improvement. In this sense, a survey‐based research was conducted in a developing country from which the aim of this paper is to identify and analyse the tools and techniques used in the stages of the DMAIC.Design/methodology/approachThe paper presents parts of the results of a descriptive survey conducted by a postal questionnaire answered by more than 60 Six Sigma users. Specific results of tools and techniques applied in Six Sigma are compared with those prescribed in the literature.FindingsThe results confirm the use of Six Sigma tools and techniques suggested by the literature. It also points out that Six Sigma needs to be supported by measurable and reliable data, and thus that the use of tools and techniques is indispensable to the use of the DMAIC.Research limitations/implicationsThis is not a probabilistic survey and, therefore, the generalisation is not feasible.Practical implicationsThe paper may assist either academic and practitioners when teaching, researching and applying tools and techniques in Six Sigma.Originality/valueThis paper is one of the few published studies that report tools and techniques applied in Six Sigma programme in developing countries.

Purpose The purpose of this paper is to investigate Six Sigma implementation in the subsidiaries of General Electric (GE) located in Brazil and to explore the role of the quality culture of headquarters in overcoming common obstacles to Six Sigma implementation reported by other studies. Design/methodology/approach An exploratory survey was the basis for gathering data for this study. A structured questionnaire was developed covering issues related to Six Sigma implementation, such as experienced benefits, main outcomes, and metrics adopted by companies. Data from eight GE subsidiaries were qualitatively analyzed. The findings were discussed in the light of other studies conducted in Brazil as well as in other developing countries in the context of the role of existing quality culture in overcoming barriers to Six Sigma implementation. Findings The findings revealed that Six Sigma at GE subsidiaries achieved better results in comparison with the results obtained by other Brazilian companies reported in the literature. GE quality culture aspects such as top management commitment, high investment in training, recognition schemes, and development of a well-planned infrastructure were identified as valuable to overcome common barriers to Six Sigma implementation. Moreover, the findings showed a strong alignment with the goals and practices of GE headquarters, which is an evidence of the quality culture that exists in GE and that allows all GE businesses achieve benefits with Six Sigma. Originality/value Since limited empirical research has been conducted concerning Six Sigma implementation in developing countries, this paper aspires to contribute to Six Sigma body of knowledge by illustrating the practices of a world benchmark corporation.

Purpose -The purpose of this paper is to present part of the results from a survey on Six Sigma, more specifically to identify the best practices in the use of the Six Sigma methodology. Design/methodology/approach -Data were collected in an exploratory-descriptive survey on Six Sigma adoption in companies operating in Brazil. Then, the paper presents and discusses best practices in Six Sigma application. Findings -The results point out relevant aspects related to the professionals involved with the program, the number of projects developed per year, as well as the return on investments made by companies. It is concluded that a good proportion of respondents adopt best practices according to the literature, but the subject needs a more detailed investigation of the financial benefits achieved with its application.Research limitations/implications -It is important to stress that the importance of some of these exemplary aspects vary with the type of company but, overall, they might be generalised within the sample. Practical implications -The results show that there are relevant points when applying Six Sigma that should be considered by companies interested in adopting it. Originality/value -As the application of Six Sigma is relatively recent and there is little data published about its utilisation in a developing country, it is important to expand knowledge on this subject. The best practices identified in this paper may be useful to Six Sigma users and academics.
