Industry 4.0 presents a new manufacturing model through the intensive use of new technologies in the pursuit of improving processes in the value chain. The use of digital technologies and the application in the industry in general influence the value chain of products, business models and commercial integration, which can improve the competitiveness of companies. This text seeks to understand the importance of data connectivity in the value chain processes of the automotive sector, in order to identify and analyze the relevance of data connectivity between the company, suppliers, customers and partners. The data were collected through a survey applied to professionals in the automotive segment, the observational method and bibliographic research. The results showed that although the use of data to define the business is relevant, investments in digital technologies are insufficient. Data connectivity between companies, suppliers, customers and partners were identified as essential, but it still does not occur as expected.
