Purpose This paper aims to present a systematic review of design for six sigma (DFSS) methods applicable to the product development process (PDP) of durables goods and identify a research opportunity on the subject proposing integration of DFSS and a reference model for the PDP. In this way, through the analysis of the theoretical references identified in the scientific databases, it was possible to propose a conceptual model for the PDP oriented to the DFSS. Design/methodology/approach This paper is based on the theoretical framework presented in peer-reviewed scientific research papers during the period 2000 to 2018 on the theme DFSS applied in the PDP, as well as such as the product development tools/techniques and statistics addressed. By means of key words defined by the acronyms of DFSS methods (DMADOV, ICOV, DMEDI, IDOV, DDOV, PIDOV, DMADIC, DCCDI, DMADV, IDDOV, CDOV and DCOV), DFSS and the acronym DFSS. Applying Boolean expression during the conduction of the searches through the scientific evidence at the Brazilian scientific database platform (Capes database). This database platform is maintained by coordination for the improvement of higher education personnel, which including Emerald Insight (Emerald), Scopus (Elsevier), Science Direct, SpringerLink, Taylor Francis, Scielo (Web of Science), Wiley Online Library, Web of Science (Clarivate Analytics), etc. It was obtained, by means of the searches, 269 papers related to subject DFSS, of which 18 papers had been critically selected for the composition of a conceptual model for the process of development of product guided to the DFSS. Findings This study presents a review of the literature (systematic review and content analysis) on DFSS and its effectiveness for the PDP. The DFSS methodology is disseminated in the scientific literature through a variety of methods that are often mistaken for the six sigma methodology – DMAIC, which is directed toward process improvement. The PDP integrated with the DFSS concepts contributes to eliminating possible failures during the design of a new product, directing to reduce costs and improve the quality of the product and process. Practical implications This paper presents a literature review that guided to a proposal of a preliminary conceptual model DFSS focused on the process of product development with the purpose of being a friendly model that meets the dynamics of the organizations and the expectations of the consumers. Originality/value Through the systematic review and content analysis, it was possible to observe that the DFSS methods applied to product development are not related to the PDP reference models available in the literature. In this way, the fusion of the concepts of the DFSS methods and PDP reference models for the construction and proposition of a preliminary conceptual model DFSS oriented to the process of product development intends to contribute in the development of new products with the reduction of time, reduction of the cost, competitive price and consumer satisfaction.

Purpose The Design For Six Sigma (DFSS) methodology is one of the most important to achieving excellence in an organization’s product development process. This paper aims to propose a roadmap for product development based on the DFSS for the consumer durables manufacturing industries. The proposed roadmap presents a systematic approach to the phases of the product development process, integrating the statistical techniques and quality tools that should be used in each phase. Design/methodology/approach This study presents a detailed roadmap for product development, which was built by identifying gaps in the DFSS methods, based on previous studies on the subject. In this step, the opportunities are provided in all phases from creation to discontinuation of the product in the market. In addition, the roadmap presented was validated by team of stakeholders in the product development process of different industrial companies. Findings The proposed roadmap for the product development process based on six sigma design suggests a visual tool with sequential steps and techniques that allow you to follow the evolution of the development process from idea conception until the product is discontinued in the market. Identifying the priorities of organizations, especially the consumer, regarding the quality and reliability of the product. Practical implications The roadmap seeks to facilitate an understanding of the important stages of the product development process and to provide an approach to improving and optimizing the product before the manufacturing process step through the principles of DFSS methodology. This research provides a guide step by step to apply statistical techniques and quality tools in the product development process to achieve high quality and six sigma level in the manufacturing process. Originality/value The proposed roadmap of this research combines design for sigma and product development concepts, covering a wide spectrum of relevant activities that include the product development process, the application of statistical techniques and the design of high-quality durable consumer goods to match manufacturing technologies.

Business Process Management (BPM) é um conceito que tem sido amplamente discutido nas organizações e sistemas de gerenciamento de informação. Assim, o objetivo principal deste artigo é apresentar, por meio de uma revisão da literatura, o tema buscando ilustrar sua versatilidade de aplicação bem como ganhos em indicadores de produtividade e gestão em organizações de manufatura industrial e serviços. Deste modo, constatou-se a relevância dos processos como elemento essencial para o desempenho organizacional e que estes têm crescido devido à forte competição em relação ao custo, tempo, qualidade, aumento da complexidade do produto e requisitos dos clientes. Concluiu-se, por fim, que entender os processos de negócios em uma organização e direcionar ações estratégicas na busca pela potencialização dos benefícios, que contribuam para percepção de valores de produtos e serviços, entregues aos clientes é um desafio da gestão moderna.

Engineering design with innovative characteristics that offer additional benefits to the customer is a process consisting of complex activities that require research, planning, and systematic methods. A prominent product development process has been driven by technological innovations used to assist the disabled in acquiring greater autonomy and performing daily tasks. Assistive product development has ensured the disabled more excellent prospects, contributing to providing or expanding the functional abilities of people with disabilities, resulting in the promotion of independent living and inclusion. This paper aims to develop a prosthetic device to aid patients with hand agenesis in practicing swimming based on the engineering design approach. The assistive product development was made based on the four phases: (i) demand perception, (ii) product projection, (iii) product characterization, and (iv) optimization. In addition, it was used for Monte Carlo simulation, multivariate analysis, and tolerance interval analysis techniques in the product development phases. We developed this approach as an alternative to classical engineering design used in the additive manufacturing process for prosthetic devices. The assistive product set aims to significantly stimulate the hand agenesis patient in physical activity, representing one of the doors of entry for social inclusion, providing a better quality of physical and emotional life for the individual with a disability.

Changes in the world market and consumer expectations have changed the way organizations develop new products. Meeting these challenges means doing better from early stages of design, avoiding possible failures and adjustments at a late stage in the development process. Design For Six Sigma (DFSS) has been successfully applied in the product development process (PDP), with the purpose of ensuring convergence to customer specifications, ensuring reliability in product development, reducing or eliminating operational vulnerabilities and increasing product robustness with use of appropriate techniques and tools. This study showed that there is no systematic DFSS structure integrated with a reference model for the product development process that encompasses the entire process, from observing the consumer's need to discontinuing the product in the market. This paper proposes a conceptual model for the product development process oriented to DFSS, based on a systematic study of existing DFSS methods with the integration of a PDP reference model. The research strategy of this study sought to understand the phases of the existing DFSS methods, as well as to identify the factors that determine or contribute to the application of these methods in the product development process. The investigation of the theme showed a lack of standardization of a DFSS method integrated with a reference model for the product development process, which allowed the identification of 11 activities from each phase of the DFSS methods, which were aligned with the 14 activities proposed by the reference model for the MOP & D product development process. This study led to a consensus in the construction of an integrated conceptual model oriented to DFSS concepts with a friendly characteristic for application in the product development process of durable goods.
