Day-to-Day Management of Information Systems 

It must be emphasised here, that a system once implemented, requires day-to-day management to ensure its proper functioning. In this connection it must be noted that this responsibility involves consideration of systems documentation, maintenance, user support and security aspects. 

It is obvious that one person should have the overall responsibility for the system: The number of staff required for system support and maintenance depends upon the size of the system and its service functions as well as the number of users. Systems normally trigger off five types of activity: documentation, maintenance, security, user support and planning. All these activities are to be coordinated by the systems manager. Of these five activities; maintenance, user support and security are considered most important for the effective function of the system as a whole.
