Abstract Paper aims This article aims to evaluate the impact of Lean Production (LP) practices implementation on the supply chain of a public hospital. Originality Most implementations fall short of their goals because they are done in a fragmented way and not from a system-wide perspective. Our approach allows to anticipate errors of misguided LP implementations in healthcare organizations. Research method The implementation of a set of LP practices in the hospital`s supply chain was assessed by computational simulation modelling, focusing on one of the most financially important product families. Main findings Since the simulation model considers the variability of suppliers and customers as inputs, it allows the verification of the proposed inventory policies effectiveness, in order to avoid affecting the service level. Implications for theory and practice The proposition of a method that integrates value stream mapping into computational simulation modelling brings a differentiated approach to analyze lean implementation in a healthcare supply chain. The simulation model supports a more assertive decision-making process on lean implementation, allowing the organization to ensure that the quality and efficiency of healthcare is not affected.
Abstract Paper aims This paper aims to critically review the Lean-based methodologies (e.g. Lean production, Lean Six Sigma, and lean government) in Public Administration to locate the critical success factors (CSFs) for lean public management implementation. Originality It is one of the first systematic literature reviews to explore the CSFs of Lean-based methodologies in the public sector with a strategic focus on the l-government. Research method This research is based on a systematic review of 83 articles that were published on Lean-based methodologies in public sector organizations in well-known academic databases. Main findings There were identified 28 CSFs, grouped by a taxonomy of five significant lean public management categories that deal with the spread of Lean-based methodologies in different public sector environments and can be used to guide continuous improvement (CI) in the public sector. Implications for theory and practice This paper can provide a better panorama to understand the present status of Lean-based methodologies towards public practices, as well as, to bridge the gap of a systematic approach (taxonomy) that could direct CI implementation in the public sector, considering a proper understanding of distinct public management characteristics, which can effectively guide practitioners, facilitating their decision-making.
Abstract Paper aims This article aims at investigating the implementation level of Lean Supply Chain (LSC) practices in hotels’ supply chains. Originality The proposed method allows to characterize LSC implementation in such an unusual context, identifying improvement opportunities and checking for discrepancies in their implementation. Research method Six different supply chains of high-quality hotels were analyzed through semi-structured interviews. Interviewees played key roles in their purchasing departments and presented large experience in the hospitality sector. Main findings Results were consolidated and for each case attributes were assigned to measure the implementation level of ten practices. Implementation scores were compared to a perceived average importance degree in order to verify convergences and divergences between the desired and actual improvement initiatives. Implications for theory and practice The applicability of LSC practices in services still needs further exploration. In the hospitality sector, whose evidence is even scarcer, this study provides a more holistic approach enabling a deeper understanding of the necessary adaptation for a successful implementation.
Resumo O baixo índice de sucesso e as mudanças estruturais e organizacionais necessárias para a Implantação da Produção Enxuta (IPE) indicam a necessidade do uso da abordagem de Gestão de Riscos (GR) para gerenciar esta transformação. Este artigo tem como objetivo apresentar um modelo gráfico para explicitar as relações entre os riscos na IPE por meio da utilização da Interpretative Structural Modelling em uma empresa e entender os motivos destas relações. O estudo está baseado em um caso conduzido na unidade de uma empresa global fabricante de componentes hidráulicos. A coleta de dados foi realizada por meio de múltiplas fontes de evidência, como entrevistas, observações, visitas à fábrica e análise de documentos. O modelo desenvolvido propiciou o esclarecimento e entendimento dos efeitos diretos e indiretos da presença dos riscos na IPE na empresa. As principais relações identificadas no modelo foram confirmadas por meio das explicações dos motivos pelos quais tais relações ocorriam no caso.
Abstract The low success rate and the complex structural and organizational changes required for lean production implementation (LPI) require the use of the risk management approach to manage this transformation. This paper aims to present a graphical model to explain the relationships between the risks in LPI through interpretive structural modeling (ISM) and to understand the reasons behind such relationships. The case study was conducted in a factory of a global company that manufactures hydraulic components. Data were collected from multiple sources, including interviews, observations, visits to the plant, and document analysis. The research contributed to clarifying and understanding the direct and indirect influences of risks that hinder the LPI at the plant. The main relationships identified in the model were confirmed by explanations of reasons for such relationships occurred in the case.
Resumo A utilização de práticas sociotécnicas é mencionada como um direcionador da satisfação dos colaboradores dentro da organização. Este artigo tem por objetivo identificar o efeito moderador da aplicação de práticas just-in-time sobre a relação entre as práticas sociotécnicas e o desempenho de qualidade de saúde dos colaboradores em empresas com implementação Lean. Foi desenvolvida uma pesquisa com 144 empresas do sul do Brasil em processo de implementação Lean. Os resultados indicam que as práticas sociotécnicas apresentam relação significativa com o desempenho da empresa em qualidade e saúde dos colaboradores, e a implementação de práticas just-in-time não prejudica o desempenho desses indicadores nas empresas.

Abstract The use of Socio-technical practices theory is mentioned as a satisfaction indicator of the work force within an organization. The purpose of this article is to identify the moderating effect at applying just-in-time practices on the relationship between socio-technical practices and the performance of the employees' health quality in such companies. We carried out a survey with 144 different companies from Southern Brazil that are undergoing a lean implementation. Results indicate that Socio-technical practices have a positive significant relationship with such performance, and the concurrent adoption of just-in-time does not undermine quality and workers' health in the companies.
