Elements of Management Information System They Include:  Information;  System;  Information Systems; and  Management Information Systems. INFORMATION This refers to data that has been processed in a way that it is meaningful to the recipient. The quality of source of data affects the value of Information. Different managers (levels) take different types of information. Characteristics/Qualities & Attributes of good Information These include:        Completeness (should have all necessary details); Accuracy; Clarity (ability to comprehend); Reliability; Timeliness; Volume; Channels of Communication; and Cost.

Roles of Information in Management The roles include the following:1) Improved knowledge; 2) Helps in reduction of uncertainty :Uncertainty exists when there is less than perfect knowledge but rarely is there a perfect knowledge. Relevant information, therefore, helps to reduce the unknowns and this is relevant particularly in planning and decision-making; 3) Acts as an aid to monitoring and control: By providing information about performance and the extend of deviations from planned levels of performance, management can better be able to control operations 4) Used as a means of communication.

It is usually said to be non-programmable and cannot be preplanned the same way that a structured decision can be. It will usually occur less frequently and will be non-routine, that is, there is no prepared decision procedure for unstructured decision either because it does not occur frequently enough to warrant one.

Semi-structured Decision Falls somewhere between the two categories above and involve elements of human judgment and has characteristics of standard procedures and some programmed elements. Levels of Management Decision-making These include: Strategic, Planning and Control Levels;  Tactical, Planning and Control Levels; and  Operational, Planning and Control Levels.
