The relevance of digital transformation (DT) is acknowledged across industries, including cultural tourism. However, existing frameworks for digital maturity in this sector are limited and fragmented. This lack of a comprehensive framework hampers the ability of cultural tourism organizations to effectively assess their digital maturity, address challenges related to DT, and formulate strategic roadmaps for digital initiatives. Therefore, this paper develops a Digital Maturity Model (DMM) tailored specifically for cultural tourism organisations, to drive them in their DT journey, towards digital excellence. The study conducts a comparative analysis of existing DMMs across various sectors to identify key dimensions and sub-dimensions relevant to the context of cultural tourism. This analysis set up the foundations for developing a comprehensive model for assessing digital maturity in cultural tourism organizations. The comparative analysis reveals seven principal dimensions consistently emerging across existing DMMs and crucial for cultural tourism organisations, specifically: Strategy, Organization, Culture, Employee, Tourists, Technology, and Operations. Each dimension is further divided and characterized into twenty sub-dimensions, providing a comprehensive framework for assessing digital maturity in cultural tourism sector. This study contributes to the literature by providing a tailored DMM specifically designed for cultural tourism organizations, addressing the unique challenges and requirements of the sector. It offers a foundation for developing DT strategic roadmaps and advancing the maturity model field further, particularly in the cultural tourism sector. The proposed DMM offers practical support for managers, employers, and other stakeholders involved in strategic decision-making within cultural tourism organizations.
