There are three basic methods of job evaluation: (1) ranking, (2) classification, (3) factor comparison. While many variations of these methods exist in practice, the three basic approaches are described here.
Ranking Method
Perhaps the simplest method of job evaluation is the ranking method. According to this method, jobs are arranged from highest to lowest, in order of their value or merit to the organization. Jobs also can be arranged according to the relative difficulty in performing them. The jobs are examined as a whole rather than on the basis of important factors in the job; and the job at the top of the list has the highest value and obviously the job at the bottom of the list will have the lowest value.
Jobs are usually ranked in each department and then the department rankings are combined to develop an organizational ranking. The following table is a hypothetical illustration of ranking of jobs.
Table: Array of Jobs according to the Ranking Method
Rank Monthly salaries
1. Accountant Rs 3,000
2. Accounts clerk Rs 1,800
3. Purchase assistant Rs 1,700
4. Machine-operator Rs 1,400
5. Typist Rs 900
6. Office boy Rs 600
The variation in payment of salaries depends on the variation of the nature of the job performed by the employees. The ranking method is simple to understand and practice and it is best suited for a small organization. Its simplicity, however, works to its disadvantage in big organizations because rankings are difficult to develop in a large, complex organization. Moreover, this kind of ranking is highly subjective in nature and may offend many employees. Therefore, a more scientific and fruitful way of job evaluation is called for.
Classification Method
According to this method, a predetermined number of job groups or job classes
