Rooted in research through design and participatory design methodologies, the civic tool integrates a data dashboard, stakeholder committee, and structured co-design sessions to facilitate collaborative analysis and intervention planning. The civic tool was developed in partnership with municipal authorities, law enforcement, NGOs, and social services, and reflects their institutional priorities while centering community knowledge. We describe the iterative co-design process, including stakeholder workshops for design, validation, training, and evaluation. The civic tool’s impact on stakeholder trust, collaboration, and decision-making was assessed through surveys and open-ended questionnaires. Our findings show that stakeholders valued the inclusive design approach and data-driven collaboration while revealing barriers in communication, data literacy, and operational coordination. Furthermore, political and institutional support was identified as critical to the civic tool’s success. This paper contributes to research on community technologies by demonstrating how civic tools can be collaboratively developed to navigate wicked social problems through participatory design.
