Abstract
Information systems (IS) play a vital role in our daily life. They collect, store, organize and distribute data in structured and organized ways to improve people's daily activities in the most efficient and effective manner. To achieve that, functions and structures are mixed together in a dynamic way to construct an information system with sophisticated capabilities beyond sending emails and publishing data online. Consequently, enterprises and government departments allocate huge financial and human resources for the development of interconnected information systems. However, failures in information systems projects have been growing in the last few years despite their massive allocated resources. That means any IS projects that do not meet their objectives and goal have gone beyond budget or not completed within the agreed time. While there are several factors triggering these failures, this research aims to investigate and address the key factors that are responsible for failure within information systems in various regions, The work conducted includes identifying different role of information systems components, comparing two important information systems success/failure models namely DeLone and Mclean model and ITPOSMO model, and summarising critical success/factors for information systems from various regions. The research findings can be used for developing an framework for effectively managing Information System.
