Job evaluation involves systematically determining the value or worth of jobs in an organization. It answers questions like which jobs to evaluate, who will evaluate, and what criteria to use. There are analytical methods like point ranking and factor comparison, and non-analytical methods like ranking and grading. Ranking simply compares jobs based on overall worth. Grading groups jobs into classes and grades with increasing responsibilities. Banding groups similar jobs together into bands. The objective is to determine pay levels and hierarchies based on duties, skills needed, and other job factors.
