Abstract

Purpose The purpose of this study is to explore the relationship between Lean manufacturing and Industry 4.0 for small and medium size of enterprise in Japan and Brazil. Design/methodology/approach The authors conducted a quantitative survey (20 companies in Japan and 30 companies in Brazil) combined with a qualitative interview (2 companies in Japan and 15 companies in Brazil). Findings According to the quantitative study, 90% of them practice Lean manufacturing and 40% of them practice Industry 4.0. In the qualitative study in Brazil, four managers responded that the Lean manufacturing is a prerequisite for Industry 4.0 since any production process with waste cannot be productive, even with sophisticated digitalization technology. Originality/value The authors explored further the relationship between “defensive Digital Transformation (DX),” which is based mainly on Lean manufacturing, and “offensive DX,” which relates to customer value creation through Industry 4.0. This study clarifies the relationship and plays as a roadmap to develop better the manufacturing from current status to the vision of Industry 4.0.

精益生产成熟度是工业 4.0 的先决条件吗？日本和巴西中小企业调查

本研究旨在探讨日本和巴西中小型企业精益生产与工业 4.0 之间的关系。作者进行了定量调查（日本 20 家公司和巴西 30 家公司），并结合定性访谈（日本 2 家公司和巴西 15 家公司）。在巴西进行的定性研究中，四位经理回答说，精益生产是工业 4.0 的先决条件，因为任何存在浪费的生产流程都不可能具有生产力，即使采用了先进的数字化技术。这项研究阐明了两者之间的关系，并为制造业更好地从现状发展到工业 4.0 的愿景提供了路线图。
