This article describes how companies in the industrial sector are leveraging key competencies to strengthen their Lean Management initiative, contributing to their competitiveness and sustainability. The aim is to improve their ability and expertise to adapt to market change, innovate, maintain their competitive edge and reduce the risks associated with economic uncertainty. Companies set objectives by analyzing the synergies between these areas, identifying key competencies and assessing their impact on Lean Management. Our approach borrows these elements from a range of articles and reviews by experts in Lean Management, Industry and Education 4.0. We exploit technological mutations linked to artificial intelligence, aimed at developing systems and algorithms for creating programs, personalizing employee training, analyzing data on learner performance and identifying trends that predict future actions. These are techniques that highlight the need for an organizational learning culture in professional development, responding to the problem of adapting employees to technological change, the CDIO approach, creating an educational revolution 4.0. These discussions place the human being at the heart of Lean Management 4.0, hence the importance of continuous improvement and adaptation to change for sustainable competitiveness.
