An information system is the basis of a hotel as a business system. Its role is to improve the processes involved in performing, managing and strategically planning business operations. It enhances the intangible features of services and increases process and service quality through improvements and innovations. As a business system, a hotel consists of a number of interrelated subsystems. A feature of modern hotel operations is the existence of an integrated hotel information system through the use of computers. This system comprises several components (Hardware, Software, Orgware, Lifeware, Netware and Dataware) that must all possess the same level of quality. Only by continuously analysing the quality and alignment of all components is it possible to gain insight into the global quality of a hotel information system and to ensure a more efficient management process. This paper presents the results of a survey conducted among 72 hotel managers from Croatia concerning the importance of the individual components of a hotel information system.
