Rising city-life growth has resulted in a world population where the majority of people live in cities. However, cities are not yet prepared and designed for this increase and are confronted with a need for urban regeneration. The landscape of urban regeneration is next to social, political and economic sustainability, challenged by implementing a comprehensive vision and long-term growth. Thereby, various methods are implemented to involve relevant stakeholders early in urban regeneration projects, focusing on a highly collaborative approach to establishing an integral vision. A robust relationship between the involved stakeholders is desirable to cope with unexpected circumstances along the process and deal with these projects’ complex and uncertain nature. Collaboration factors within the informal domain that enhance the quality of collaboration can be distinguished from literature. This research aims to create awareness amongst the project team to engage with this soft side of collaboration actively. Therefore, the Design Science Research approach is applied. A multiple case study conducting semi-structured interviews resulted in practical (inter) actions to be executed during urban regeneration processes. These findings are translated into a roadmap for (inter)actions, which presents the (inter)actions to be performed along the process of urban regeneration by the project team.
