The digital twin is one of the promising technological concepts of the Industry 4.0. However, few research deals with the cooperative use of the digital twin. Through this PhD project, I aim to study how the digital twin of the French railway infrastructure can improve the coordination between the stakeholders of its maintenance. In order to study this, I am conducting a multisited ethnography to identify the coordination mechanisms that are involved in the work scheduling activity. I am planning to study more in depth how the digital twin can support cooperative practices by using technological probes. PhD Research context
