PurposeEco-museums safeguard the cultural authenticity and the historical identity of the place in which they operate. Conventional organizational models and management practices are generally employed to achieve this institutional aim. Conversely, innovative solutions – such as digitization – are overlooked. Adopting a service quality management perspective, the article intends to examine the role of managerialization and professionalization in triggering eco-museums' digitization.Design/methodology/approachAn empirical analysis involving 126 eco-museums operating in Italy as of 2018 was designed to investigate the implications of managerialization and professionalization on the eco-museums' propensity to embark on a digitization process. Two different forms of digitization were examined: (1) the presence of eco-museums in the digital environment; and (2) the exploitation of digital tools for service delivery. The mediating role of two “soft” total quality management (TQM) practices, i.e. people centredness and strategic focus on visitors' experience, was contemplated in the empirical analysis.FindingsThe research findings suggest that managerialization and professionalization have ambiguous effects on eco-museums' digitization. Nevertheless, they indirectly contribute to a greater digital presence of eco-museums and to a larger use of digital tools for service delivery through an increased use of soft TQM practices.Research limitations/implicationsManagerialization and professionalization are likely to foster the digital transition of eco-museums, which advances their ability to protect and promote the local cultural heritage. Soft TQM practices intended to achieve people-centredness and to enhance the visitors' experience should be exploited to stimulate the eco-museums' digitization.Originality/valueThe article examines the triggers of eco-museums' digitization, providing some food for thought to scholars and practitioners.
