On what basis job evaluation should be done?

Job evaluation is the systematic approach of measuring job worth. It is based on certain principles which include:
a.The job evaluators must rate job and not the employee.

b.Job analysis must be done before job evaluation is initiated.

c. As far as possible, the pooled or combined judgments of several persons should be employed in evaluating jobs.

d. A decision must be made concerning what jobs are to be covered by a single evaluation system. Only similar jobs should be grouped together for the purpose of evaluation.
