ABSTRACT
To gain better competitive advantage in the market, the organization are using information systems. Most of the organizations either have established the information system or they upgrade their information system. But still there are lots of hurdles for gaining information system success. There have been a large number of analyses of critical success factors of information system projects in the literature, but there is shortfall in research efforts in studying failures globally and particularly in India. Therefore this chapter attempts to study empirically the obstacles coming in Information system success. A questionnaire survey has been conducted to know the failures factors for not updating the information system timely. The survey has been done on two prominent telecommunication organization, one having successful IS (Reliance Communication) due to its continuous updation with respect to time, industry and executives other (Puncom, Mohali) don't have. As India is the second largest country in terms of mobile users in the world therefore the study of this industry is strategically and economically important due to its high potential for the growth of the country.
