Stakeholders must purposely reflect on the suitability of process models for designing tourism experience systems. Specific characteristics of these models relate to developing tourism experience systems as integral parts of wider socio-technical systems. Choices made in crafting such models need to address three reflexivity mechanisms: problem, stakeholder and method definition. We systematically evaluate application of these mechanisms in a living lab experiment, by developing evaluation episodes using the framework for evaluation in design science research. We outline (i) the development of these evaluation episodes and (ii) how executing them influenced the process and outcomes of co-crafting the process model. We highlight both the benefits of and an approach to incorporate reflexivity in developing process models for designing tourism experience systems.
