The rationale of an information management system is that all information should move according to a formal scheme and direction. The process begins with an examination of the output requirements. One way is to classify information based on the level in the organization at which it will be used. It should be remembered that too much information actually may hinder a manager's performance. The purpose of this step is to improve the overall quality of the information.
Collection involves gathering and recording information.
Evaluation involves determining how much confidence can be placed in a particular piece of information. Storage consists of filing information so that it can be referred to, as needed. It may be needed to defend a decision. Dissemination entails getting the right information to the right manager at the right time. This is the overriding purpose of an information management system.
