One of these areas is hotel information system. Many operations, such as check-in, check-out, and food and beverage, are performed owing to information technologies. Package programs are used for managing hotel operations. Software provides reporting, filtering, remote accessing, and cost control services which are important key parameters of decision-making processes of hotel managers. Cost control is one of the most important operations in hotel management. Cost control service of package programs assists managers in monitoring overall cost and computing each department＇s partial cost and serves information to the different departments of hotels using information technologies. Cost control is important in the departments which are profitable in a hotel. Food and beverage is one of these profitable departments, which is the second profitable department in hotels. It makes profit between mostly 20% and 40%. This research aims to understand effects of information technologies during decision-making processes. The sample of study is food and beverage managers in five-star hotels in Istanbul. Questionnaire was applied to 45 participants.展开更多
