In 2018, the Indonesian government launched the Making Indonesia 4.0 Roadmap under The Industrial Revolution 4.0 era. This road map aims to increase industrial competitiveness and make the nation one of the world’s top 10 economies by 2030. The role of the Internet of Things (IoT) in The Industrial Revolution 4.0 is important to improve work efficiency and reduce companies’ costs. Although several manufacturing companies in Indonesia have successfully implemented this technology, so it is important to identify the critical success factors in its application for other companies. Therefore, this study discusses the essential factors of success for implementing IoT in automotive companies in Indonesia, which have differing specific application characteristics from the conditions in other countries. The Delphi method obtained data from 8 dimensions and 32 sub-dimensions. These included the finance, regulatory, people and management, operation, technology, innovation, ideas, and resource dimensions. Other automotive companies can use the results as a reference in implementing IoT and evaluating and improving their business performance, as well as formulating the right strategy to achieve excellence in the long term.
