# 2.2 Information
      Attributes of Information

Some of the important attributes of useful and effective information are given as follows:

Availability - It is a very important aspect of information. Information is useless if it is not available at the time of need.

Purpose/Objective - Information must have purposes/objective at the time it is transmitted to a person or machine, otherwise it is simple data.

Mode and format - The modes of communicating information to humans should be in such a way that it can be easily understandable by the people. The mode may be in the form of voice, text and combination of these two.

Current/Updated - The information should be refreshed from time to time as it usually rots with time and usage.

Rate - The rate of transmission\reception of information may be represented by the time required to understand a particular situation.

Frequency - The frequency with which information is transmitted or received affects its value.

Completeness and Adequacy - The information provided should be complete and adequate in itself because only complete information can be used in policymaking.

Reliability - It is a measure of failure or success of using information for decision- making. If the information leads to correct decision on many occasions, we say the information is reliable.

Validity - It measures how close the information is to the purpose for which it asserts to serve. For example, the experience of employee supports in evaluating his performance.

Quality - It means the correctness of information.

Transparency - It is essential in decision and policy making. For example, the total amount of advance does not give a true picture of utilization of fund for a decision about the future course of action; rather deposit-advance ratio is perhaps more transparent information in this matter.

Value of Information - It is defined as the difference between the value of the change in decision behavior caused by the information and the cost of the information.
