Information system management is the relationship phenomena between the people, business procedures and technologies in doing/undertaking business process. They are specific from the normal systems management since their use is for analyzing the information system which is applied in various business processes. Centralized information management is where the business operations and systems are operated from a central point/ distributing point. The information is sent out to the other divisions through such a central point. Either, this point also receives information from the external terminals.
Through this method, organizational information is coordinated from one central place before being conducted to the other outlets and points of business management. On receiving the information, the central unit will identify the external point from which the information comes from and sends the adequate feedback. This is an advantage to the business information flaws and misuse. From a coordinated approach of central unit, the information can be monitored, analyzed, before giving out the correct feed back. It is usually cost effective to big organizations.
Either, it avoids information misuse through corporate intelligence and industrial espionage. (Nickerson, 1994) Decentralized information management is where the information is controlled from more than one central division. Each division monitors the information of its relevant department before sending and remitting the adequate response. Generally, it is economical to very big organizations where huge volume of information flows in and out of many departments. Decentralized information management avoids the flaws of centralized system where huge information cannot be supported by one central point.
Through the use of such many decentralized points, the relevant information can be disseminated across the relevant point. It seeks to ensure cost efficiencies in information management where the cost of information management through a central point is highly costly and perhaps inefficient to the organization. Either, it seeks to ensure easy contacts of information at various departments without remitting information to a central point which may even be far. (Nickerson, 1994)
