This paper focuses on the importance and impact of Industry 4.0 and digital transformation to create added value for organizations and society as a whole. The Fourth Industrial Revolution (Industry 4.0), with its digital transformation, had a great impact by changing almost all aspects of global socio-economic life. The digital transformation in the expansion of Industry 4.0 is no longer just a choice but has become an unavoidable development trend for companies for their further development. Digital transformation is the transformation of business activities, processes, products / services, and models in order to take full advantage of the possibilities of digital technologies, which characterize the development, growth, innovation and so-called. disruptions (disorders), ie situations where new technologies compete with the traditional business way. This competition can help organizations use digitized information and processes to create a new, more efficient, and more appropriate business model. Digital technologies in the oil industry can have a significant impact on their business as they contribute to increasing hydrocarbon recovery, ensuring security in the business ecosystem, and improving operational reliability. The process of digital transformation is described in this paper on the example of oil industry company PetroVietnam.
