The term industry 4.0 (I4.0) was coined in Germany in 2011 and can be seen as the movement to digitize and automate processes in the field of manufacturing, its implementation requires a workforce with new qualifications. In this article, through a literature review, public policies for the implementation of I4.0 were analyzed in Germany, China, the United Kingdom (GB), Sweden, Japan, and Brazil, cataloging them into three themes, Employees - issues related to human Resources; Production – referring to the physical resources used in the production process; Social – relating to the creation and sharing of knowledge among workers and the effects on society in general. The research revealed that Germany, China, GB and Japan have greater similarities in their way of adopting I4.0, especially in the great focus on research, adaptation of their human resources and constant professionalization of the workforce, however China differs especially in the way of distributing it, focusing on large and centralized companies, while the others focus on a more democratic distribution, covering more regions and small and medium-sized companies. Finally, as for Brazil, despite having some initiatives in the right direction, they are few and fail to resolve the lack of understanding of the benefits of I4.0, the lack of technological infrastructure and financial restrictions.
