Keith Porter: How Information Systems can be used in a businesses,such as airlines, to assist in the decision making process?|||Management Information Systems were initially desgined for decision support and were called decision support systems. For an Airline, you can allow reservations through a computer. With the proper MIS software loaded you can gather information like the demography, geographical, labor class wise etc; the different segment using your services more often and can run your mission to cater to their needs and this will improve your customer satisfaction and customer retention. An accounting MIS package can give you information on your performance at the press of a key and help you take decisions faster on how to improve your performance for growth or improved services. You can control your operations to see where you loose money the same way and cut back on unnecessary expenses. You can manage your inventory, food and beverage, seat allocation, luggage information, landing schdules, take off schedules, either in isolation or integrated to take decisions. You can even creates alerts when criticalities are reached where decisions has to be made manually. Rerouting, transferring passengers etc; can be handled usin these decision support systems cost effectively. Finally you can control the payroll, material purchases, marketing decisions etc; using MIS and decision support softwares tailor made for your business.|||Decision making is a set of trade offs. The decision maker look at the alternatives available and picks up depending upon the time on the hand in the face of risk. Decision making process becomes effective only if decision behaviour under psychological stress is taken into account. The system if standardised, information can be structured so as to identify the areas of deviations from the set standards to work on. Managers use reporting system to hv control and getting insights into what is happening and going on in the present context. Good bye.
