Industry 4.0 is a topic widely studied in both academic and professional literature. This new era is expected to impact every corporate function. The industry 4.0 should not be considered as a finite project but rather a transformation to be implemented progressively. Literature related to the implementation covers technical and managerial challenges but lacks empirical studies and does not provide a strategy of the implementation. In this study, a survey was conducted among Moroccan companies that have implemented industry 4.0 Technologies. The status of those companies was assessed and analysed to identify the key challenges to be encountered. The original contribution of this paper is to present a practical guideline implementation for Moroccan companies.
