The promotion of DX, which aims to reform corporate operations by utilizing digital technology, is one of the important issues for companies. Developing in-house engineers is an important issue for promoting DX. In this paper, we propose a practical DX propulsion training method by implementing prototype system construction. Specifically, we will propose a method for developing DX promotion capabilities using four prototypes for IoT, AI, big data, and cloud utilization, which are necessary for DX promotion. In addition, we propose a method for developing DX promotion capabilities by utilizing a prototype that integrates these four technologies, and discuss the practice and evaluation of these training methods.
