Abstract(s)
Numa época em que as organizações são confrontadas com novos desafios e a adversidades
externas que, normalmente, configuram riscos não identificados de forma atempada e, por
conseguinte, não avaliados, mas cujo impacto, quando revelado, são passíveis de colocar em causa
a segurança e a saúde das pessoas, o ambiente, a evolução do próprio negócio e até a
responsabilidade social da organização.
Torna-se prioritário estudar novos princípios e ferramentas capazes de agilizarem e potenciarem
assertividade na tomada de decisão de todos os intervenientes das organizações, assim como
melhorar a eficácia e a eficiência dos processos, tendo como prioridade o combate ao desperdício,
de qualquer natureza, função da valorização percecionada pelos próprios clientes.
Sabendo-se que filosofia Lean Seis Sigma é utilizada com sucesso há já alguns anos, em vários
setores de atividade, a presente dissertação tem por objetivo encontrar respostas para a seguinte
questão de investigação - Qual o impacto da filosofia Lean Seis Sigma em organizações com
Sistemas Integrados de Gestão implementados (Qualidade, Ambiente e Segurança)?
Complementarmente à pesquisa bibliográfica, foi realizado um estudo com recurso à metodologia
survey, desenvolvida através de um questionário enviado, via email, a 69,8 % das organizações
registadas na base de dados do IPAC, como detentoras de um Sistema Integrado de Qualidade,
Ambiente e Segurança (SST), com atividades distintas e localizadas em diversas geografias de
Portugal. Para concretização do estudo foram enviados 398 questionários, sendo que 20, por
dificuldades de contato, foram considerados nulos, pelo que foi validada a entrega de 378
questionários.
O período de receção das respostas decorreu de 12 a 31 de agosto de 2023, tendo sido recolhidas
e validadas 35 respostas, cujos dados foram analisados e tratados estatisticamente com recurso ao
MS Excel e ao IBM SPSS Statistics.
No domínio das ferramentas Lean Seis Sigma, apurou-se que as mais utilizadas nas organizações
são as 5S (85%) e os 5 Porquês (70%).
Quanto à combinação das respostas obtidas sobre as ferramentas Lean Seis Sigma, numa escala de
Likert de 5 pontos, foi alcançado um resultado médio de 4,0 pontos (Concordo), verificando-se
também existir uma boa consistência interna, traduzida por um alfa Cronbach de 0,847.
Conclui-se que a implementação de práticas e, sobretudo, a utilização de ferramentas associadas à
filosofia Lean Seis Sigma tem impacto nos Sistema Integrados de Gestão implementados nas
organizações, potenciando a melhoria contínua dos processos, contribuindo assim para a melhoria
da eficiência das organizações e da satisfação dos clientes.
At a time when organizations are faced with new challenges and external adversities that, normally, represent risks not identified in a timely manner and, therefore, not evaluated, but whose impact, when revealed, are likely to jeopardize security and people's health, the environment, the evolution of the business itself and even the social responsibility of the organization. It becomes a priority to study new principles and tools capable of streamlining and enhancing assertiveness in decision-making by all participants in organizations, as well as improving the effectiveness and efficiency of processes, with priority being on combating waste, of any nature, function of the appreciation perceived by the customers themselves. Knowing that the Lean Six Sigma philosophy has been used successfully for some years now, in various sectors of activity, this dissertation aims to find answers to the following research question - What is the impact of the Lean Six Sigma philosophy on organizations with Systems Implemented Integrated Management (Quality, Environment and Safety)? In addition to the bibliographical research, a study was carried out using the survey methodology, developed through a questionnaire sent, via email, to 69.8% of organizations registered in the IPAC database, as holders of an Integrated Quality, Environment System and Security (SST), with different activities and located in different geographies of Portugal. To carry out the study, 398 questionnaires were sent, of which 20, due to contact difficulties, were considered null, meaning that the delivery of 378 questionnaires was validated. The period for receiving responses ran from August 12th to 31st, 2023, with 35 responses being collected and validated, whose data were analyzed and statistically treated using MS Excel and IBM SPSS Statistics. In the field of Lean Six Sigma tools, it was found that the most used in organizations are the 5S (85%) and the 5 Whys (70%). Regarding the combination of responses obtained regarding Lean Six Sigma tools, on a 5-point Likert scale, an average result of 4.0 points was achieved (Agree), and there was also good internal consistency, translated by a Cronbach alpha of 0.847. It is concluded that the implementation of practices and, above all, the use of tools associated with the Lean Six Sigma philosophy has an impact on the Integrated Management Systems implemented in organizations, enhancing the continuous improvement of processes, thus contributing to improving the efficiency of organizations and of customer satisfaction.
