Sustainable development is an important issue for hotels as it is in all sectors. Managers try to manage processes by preserving all economic, social and environmental balances. At this point, technology is seen as the most important helper. In this context, the aim of this research is to evaluate the effects of technologies used in hotels in terms of sustainable development from the perspective of managers. In this study, interviews were conducted with the managers of 4and 5-star hotels. In total, 15 criteria have been determined. In the analysis of the criteria, the DEMATEL method, which is one of the multi-criteria decision-making techniques, was used. As a result of the findings, convenience, correct information and organizational compatibility criteria came to the fore as the first three criteria that most affected the other criteria. In addition, the criteria of competitive advantage, customer satisfaction and cost advantage were determined as the first three criteria that were most affected.
