O Seis Sigma foi criado pela Motorola na década de 1980, e foi durante anos vista como uma forma de implementar a Qualidade, vocacionada ao ganho de vantagem competitiva, através de ajuda às organizações na melhoria dos seus processos de modo a reduzir erros e defeitos nos produtos e serviços. Num panorama de crescente agressividade competitiva, somente as empresas que percebam as necessidades do mercado e que sejam capazes de responder eficientemente, poderão ambicionar alcançar um sucesso sustentável.
O conceito Seis Sigma evoluiu ao longo de anos e tornou-se numa estratégia de gestão assentado no ciclo DMAIC, adoptada pela generalidade das organizações à escala mundial.
O DMAIC, aplica-se sobretudo a programas de melhoria e/ou resolução de problemas em entidades existentes, enquanto que o DFSS, é utilizado para conceber e desenvolver novas entidades.
Pretende-se com este trabalho, compreender na íntegra os princípios da metodologia, analisar os campos de aplicação, analisar diferenças e semelhanças com outras metodologias, analisar o conjunto de ferramentas para a sua implementação e enquadrar o tema numa aplicação de soldadura de cobre com base no processo de soldadura TIG.
Comparando ao PDCA, o Seis Sigma revela maior probabilidade de sucesso
No caso de estudo, com base no Seis Sigma, assentado no ciclo DMAIC, efetuou-se uma análise, alicerçada em dados históricos de construção soldada disponíveis no Instituto de Soldadura e Qualidade e prosseguiu-se com análise de defeitos na aplicação acima descrita.
Preveu-se com este estudo, identificar os tipos de defeitos, mais frequentes resultantes dos processos TIG aplicado à soldadura de cobre, causas e efeitos.
Six Sigma was invented by Motorola in the 1980s, and was for years seen as a way to implement Quality. The aim is gain competitive advantage by helping organizations improve their process in order to reduce errors and defects in products and services. In an increasingly competitive landscape, only companies that understand the market needs , in order to respond effectively, can aspire to achieve sustainable sucess. The concept has developed over the years, and became a management strategy adopted by most organizations worldwide. The aim of this work, is fully understand the principles of the methodology, analyse the application fields to identify similarities with other methodologies, and analyse the set of tools for its implementation and frame his subject in application of copper, welded by TIG welding process. DMAIC, is mainly applied to improvement programs or fixing problems in existing entities, while DFSS is used to design and develop new entities. In Comparison with PDCA, DMAICS reveals greater propability of sucess. In case study, based on Six Sigma, sitting in the DMAIC road map, the autor will make analysis based on historical data of welded construction available in Instituto de Soldadura e Qualidade and a will also proceed with the analyse of defects in the applicatin above described. It is foreseen in this study, the identification of types of defects, most frequently obtained in copper, using TIG as welding process, their cause and effects.
