The involvement of stakeholders in large scale urban sustainable development projects (LSUSDP.s) has proven difficult. The stakeholders are distributed across the geographical area, and they have stakes not only in the LSUSDP, but in the geographical location where the project takes place. To understand stakeholder management in "distributed projects", we propose abandoning the "inside-out" perspective where the project is the point of departure, and focus on the emergence of stakeholders across time. Adopting such a performative, "outside-in," perspective on the longitudinal and digital study of a LSUSDP, we are able to map how actors became stakeholders in the project through their actions. The paper makes four contributions. First, we reconceptualize stakeholder involvement by adopting a performative perspective, whereby "stakeholders" are envisaged as emergent and non-fixed. Second, we demonstrate how such a reconceptualization may be applied to the analysis of an empirical case. Third, we show that stakeholder involvement is not merely the result of stakeholder management but something that happens over time, through the material and discursive actions of those that become stakeholders. Finally, the paper contributes with an illustration of how the online, digital footprint, of a project may be useful to understand the emergence of a project.
