Collaborative approaches to destination design require conscious and reflexive stakeholder involvement in activities and decision making. Design science studies such participatory processes by observing design teams in practice. From these observations, scientists have identified design strategies and processes that design teams use to support their work in identifying problems and developing solutions. Observing design processes in tourism destinations provides an opportunity to identify successful co-design strategies for destination design. This study presents three key co-design strategies based on data collected from five living labs in five destinations. Each co-design strategy is presented with a recommended use, suggestions for stakeholder involvement, and activities to develop solutions efficiently and effectively with the available resources. Together, the strategies provide a framework to optimise decision-making in relation to shaping destination design processes, and to validate processes and outcomes.
