Coordination, progress tracking, and communication are issues inherently linked with pursuing an objective collaboratively, and exponentially increase with the number of involved stakeholders. These challenges are shared between the well-studied and known field of economic value creation and the lesser considered, wide, and unexplored field of social innovation projects. This thesis explores the possibility of offering a universal methodology to ease the cooperation between stakeholders in any social innovation project. The primary aim is adapting the existing GUEST methodology, developed to foster innovation in startups and small-medium enterprises, to allow it to be universally available to be applied to any social innovation project.
