Elementos favoráveis e desfavoráveis na implementação do Lean manufacturing em empresas da cidade de Juiz de Fora/MG

Abstract

The objective of this research was to identify how four companies from different sectors in the city of Juiz de Fora/MG, which participated in and completed projects through the Brasil mais produtivo Program (B+P), applied Lean Manufacturing (LM) tools in their processes, and what were the favorable and unfavorable elements for implementing LM. The B+P was a federal government program, conceived by the now-extinct Ministério do Desenvolvimento, Indústria e Comércio Exterior (MDIC), which served 3000 companies in Brazil, applying LM tools to projects with a duration of up to 3 months between 2016 and 2018. To achieve this, a qualitative investigation was conducted with the following aims: (i) diagnose and analyze actions, favorable and unfavorable elements for LM implementation, as well as their results, in dialogue with the literature; (ii) examine ways to reinforce favorable elements, mitigate unfavorable ones, and stabilize results. Information was collected for evidence triangulation, using both primary and secondary data. To analyze the content of the official B+P evaluation report, the IRAMUTEQ software was employed, based on Bardin's model (2011). The main results were: (i) conceptual divergence between LM tools listed in the literature and those used in B+P; (ii) listing and detailing ten favorable and ten unfavorable elements for LM implementation; (iii) identification of the Value Stream Mapping (VSM) tool as unanimous among authors and the B+P Program regarding measurements of productive and documentary flows in LM projects.
