This report is the result of a self-initiated design graduation project that regarded positive design in a strategic design context. The goal of the project was to design and develop a tool or method that integrates positive design knowledge into strategic design processes. To get to the bottom of this, desk research and user research into the domains of strategic and positive design were conducted. Research presented opportunities to apply happiness interventions on multiple strategic levels of a product-service system. These opportunities were developed into an overview, the positive strategic design (PSD) framework. Research also presented several strategically viable implications to communicate the happiness interventions. The chosen strategy was one that was directed at design students. The students are the bridge between theory and practice and can potentially improve engagement with positive design in both areas. The strategy was to create a solution that included principles from both strategic design and positive design and incorporated the PSD framework. The final design included a tool in the form of website and a printable card set and were developed to give users the same value independent of the format that they use. Moreover, people can download the card set through the website, making it easier to use and discuss the happiness interventions in a group.
