Appraisal of one individual by another individual is a continuous process and it is natural phenomenon in human beings. This is constantly done, consciously or unconsciously in our day-to-day interaction, either in family life or in a social setting or in an organization for that matter. While the individual or a group uses appraisal in its own fashion depending upon the need of the situation, in an organization it becomes necessary to adopt a formal methodology of appraisal system because of the requirement of measuring the performance for considering suitable reward or punishment or for assessing the potential of a person to increase the responsibilities. In short, there is a great requirement for assessing the efficiency to gear up the productivity of the work force.
