The competitiveness in the corporate world has increased considerably, and to keep competitive, companies must continuously innovate their production processes. Lean manufacturing (LM) emerged as a philosophy that replaces waste in the production environment. Currently, the world experiences the fourth industrial revolution or Industry 4.0, which is based on high connectivity. To keep themselves updated, companies are integrating lean and Industry 4.0. Towards the successful implementation of Industry 4.0 technologies, it is necessary to analyze which technology best adapts to the lean installed environment. Within this context, this Master s thesis aims to analyze the synergy points between LM and Industry 4.0 and to improve corporate understanding under the joint implementation of these two strands in the manufacturing industry. Two integration frameworks between the LM and I4.0 are proposed, both aiming to assist the process of joint implementation of these two strands. To achieve this objective, a systematic literature review and a Panel of Experts were carried out to develop and validate the frameworks. Descriptive and content analyses of the proposed topics are also presented. It is suggested for future research a case study in which these frameworks are used in practice in the manufacturing industry.
