Quality Dimensions for Digital Twin Maturity in the Context of Dutch Public Spatial Planning

Digital Twin (DT) technology is being increasingly adopted by local and regional governmental organizations in the Netherlands to support spatial planning decision-making, balancing contradicting policy ambitions. These DT solutions are becoming more complex as more perspectives, based on sophisticated calculations, are added to one integrated view of the problem space. To be able to validate the quality of these DT solutions, quality dimensions are to be established. This study focuses on identifying quality dimensions for DT solutions, including legal and policy perspectives, and safeguarding public value; thereby transcending the technical focus that most contributions on quality dimensions for DTs have in the current body of knowledge. Based on empirical data collection and analysis, 15 quality dimensions were identified. Future research should focus on further operationalizing these dimensions, allowing for measuring DT solution quality on a maturity scale.
