Job Evaluation
Job evaluation is a systematic way of determining the value and worth of a job in relation to other jobs in an organization. It tries to make systematic comparison between jobs to assess their relative worth for the purpose of establishing a rational pay structure.
According to International Labour Organisation
“Job evaluation is an attempt to determine and compare methods which the normal performance of a particular job makes on normal workers without taking into account the individual performance of the workers concerned.”
According to Wendell French
“ Job evaluation is a process of determining the relative worth of various jobs within the organization so that differential wages may be paid to jobs of different worth.”
Objectives of Job Evaluation
- To determine equitable wage differential between different jobs in the organization.
- To eliminate wage inequities.
- To develop a consistent wage policy.
- To establish a rational basis for incentive and bonus schemes.
- To provide a framework for periodic review and revision of wage rates.
- To provide a basis for wage negotiations with trade unions;
- To minimise wage discrimination on the basis of age. sex, caste, region, religion.
- to enable management to gauge and control the payroll
Difference between Job Evaluation and Performance Appraisal
Job Evaluation | Performance Appraisal |
It is the assessment of various jobs to find out their relative worth. | It is the assessment of performance of different employees performing the same job. |
It takes into consideration the requirements of different jobs. | It takes into consideration the performance of different individuals. |
Its purpose is to identify the basis for fixing wages, salary for various jobs. | Its purpose is to identify the basis for decisions concerning pay raise, promotion. training and transfer. etc. |
It rates the jobholder and not the job. | It rates the job and not ‘the jobholder. |
It is done before an employee. | It is done after an employee joins and performs the job. |
Process of Job Evaluation
The process of job evaluation involves the following steps:
- Gaining Acceptance
First of all the cooperation and support of top management,employees and the trade union should be obtained through communication and participation. For this purpose conferences, letters and booklets can be used explaining the aims and benefits of job evaluation.
- Constituting Job Evaluation Committee
It is very difficult for a single person to evaluate all jobs objectively. Therefore, a committee consisting of experienced and respected representatives of a management and workers and outside experts should be constituted. Participation of employees in job evaluation will reduce their doubts and suspicion about the programme.
- Selecting Jobs to be Evaluated
Due to constraints of time and money it may not be possible to evaluate each and every job. Therefore. some key jobs may be selected in each department. The key jobs are evaluated in detail and the other jobs are compared with the key jobs. The key jobs should be representative of the type of work performed.
4.Describing the Jobs
A detailed written description of every job is prepared to indicate the duties and responsibilities involved in it. The job description is thoroughly checked to ensure that there are no omission and duplication in it. The acceptance of the employee performing the job is also obtained to the job description.
- Selecting the Method of Evaluation
There are several methods available for evaluating jobs. The method most appropriate to the job and the organisation is choosen. If possible more than one method may be used to increase the accuracy of evaluation.
- Weighting Job
A job is compared with other jobs in terms of Significant factors which may be as follows:
(a) Skill-mental and manual
(b) Experience
(c) Efforts and initiative
(d) Working conditions
(e) Responsibilities to be undertaken
(f) Supervision required
Weights are assigned to each job factor and total weights for a job indicate its relative value. Different jobs are arranged in a sequence in terms of their relative worth to the company.
- Assigning Money Values
Each job is priced in terms of its worth. In other words, the sequences of jobs in terms of their relative worth is related to a money scale.
- Periodic Review
A periodic review and revision of job descriptions will help to assuage the feelings of employees who believe that their work was not properly evaluated. Moreover, it will enable management to update job description in the light of technological and other changes. For example, automation of a job reduces physical effort, but increases responsibility.
Methods of Job Evaluation
Various methods of job Evaluation may be grouped as under
- Non-quantitative methods
(a) Ranking or job comparison
(b) Grading or job classification
- Quantitative methods
(a) Point rating
(b) Factor comparison.
- Ranking Method
It is the simplest method of job evaluation. According to this method, jobs are arranged from highest to lowest, in order of their value or merit to the organization. Jobs can also be arranged according to the relative difficulty in performing them. The following table is a hypothetical illustration of ranking of jobs.
Rank | Monthly salaries |
1. Accountant | Rs. 35000 |
2. Accounts clerk | Rs. 28000 |
3. Purchase assistant | Rs. 21000 |
4. Machine- operator | Rs. 18000 |
5. Typist | Rs. 12000 |
The variation in payment of salaries depends on the variation of the nature of the job performed by the employees.
Three techniques can be used for ranking jobs. These techniques are as follows:
a) Job Description
In this technique. a written jobs description is prepared for every job. The job descriptions are then studied and analysed. the differences between them in terms of duties, responsibilities, skill requirements, etc. are noted. Each job is assigned a rank depending upon its relative significance. Several raters may independently rank each job. The average of these ratings is calculated to determine the final ranking. The following table illustrates the procedure:
Job | Rater-X | Rater- Y | Rater-Z | Average |
A | ||||
B | ||||
C | ||||
D |
In this method, the rater is required to keep in mind all the jobs being ranked. This may not be possible when the number of jobs is large. The rater may overlook significant differences among jobs. As a result accuracy of ranking may be low. Paired comparisons can be used to overcome this problem.
(b) Pair Comparisons. In this technique each job is paired with every other job in the series. The more difficult job in each pair is identified. Rank is then assigned on the basis of the number of times a job is rated more difficult. For example, the pairs and ratings in an organisation may be as follows :
Pair | More Difficult Job | Rank |
Assistant – Upper Division Clerk | Assistant | 1 |
Upper Division Clerk – Lower Clerk | Upper Division Clerk | 2 |
Lower Division Clerk – Peon | Lower Division Clerk | 3 |
Assistant – Lower Division Clerk | Assistant | |
Assistant – Peon | Assistant | |
Upper Division Clerk – Peon | Upper Division Clerk Peon | 4 |
(c) Ranking Along a Number Line
In this technique, ranks obtained through job descriptions and paired comparisons are spread along a number line. Each job is then placed along the line on the basis of its closeness to the highest ranked job. For example, in the following number line, A is the highest ranked job, E is the lowest ranked job. Other jobs are spaced according to their closeness to the highest ranked job.
Advantages of Ranking Method
(i) It is the simplest and the oldest method.
(ii) It is very economical and less time consuming.
(iii) It involves little paper work.
Disadvantages of Ranking Method
(i) It does not indicate the degree of difference between different jobs. It merely reveals that one job is more important than others.
(ii) It involves subjective judgment because a job is not analyzed and key factors are not compared. Therefore, it is less accurate and is not fully reliable.
(iii) The rater is required to be thoroughly familiar with all jobs to be rated.
- Grading Method
(i) Job classes or grades are established. A job grade is a group of different jobs of Similar difficulty or requiring Similar knowledge and skills to perform.
(ii) Each job grade is defined in the form of a written description.
(iii) Each job is classified into an appropriate grade depending on how well its characteristics match the grade definitions. For this purpose job descriptions are carefully analysed. In this way, a series of job grades in developed and a different wage rate is fixed for each job grade.
Advantages of Ranking Method
(i)This method is easy to understand and simple to operate.
(ii) It is more accurate and systematic than the ranking method.
(iii) It is economical and therefore suitable for small concerns.
(iv) It provides an opportunity to develop a systematic organisation structure.
(v) Pay grades can be compared with those of other concerns. Grouping of jobs into grade simplifies wage administration.
(vi) This method is used in Government offices.
Disadvantages of Ranking method
(i) It is very difficult to write accurate and precise descriptions of job grades.
(ii) Some jobs may involve tasks which overlap more than one grade. It is difficult to classify such jobs in a particular grade.
(iii)The system is rigid and personal judgement is involved in deciding job classes and assigning jobs to specific classes.
- Factor Comparison Method
A more systematic and scientific method of job evaluation is the factor comparison method. Though it is the most complex method of all, it is consistent and appreciate. Under this method, instead of ranking complete jobs, each job is ranked according to a series of factors. These factors include mental effort, physical effort, skill needed, responsibility, supervisory responsibility, working conditions and other such factors. Pay will be assigned in this method by comparing the weights of the factors required for each job, i.e. the present wages paid for key jobs may be divided among the factors weighted by importance. In other words, wages are assigned to the job in comparison to its ranking on each job factor.
Advantages of Factor Comparison Method
i. It is a relatively more analytical and objective method.
ii. As few factors are utilized the chances of overlap are
iii. The procedure involved is logical.
iv. The method is flexible as there is no upper limit on the rating of a factor.
v. It is more reliable and valid as each job is compared with all other jobs in terms of key factors.
vi. Money values are assigned in a fair and objective manner depending on factor ranking.
Disadvantages of Factor Comparison Method
i. It is difficult to understand and operate.
ii. It is a time consuming and expensive method.
iii. The use of present wage rates for key jobs may lead to error in the beginning.
- Point Method
It is the most widely used method of job evaluation. Under it, jobs are divided component factors. Points or weights are assigned to each factor depending on degree of its importance in a particular job. the total points for a job indicate it. relative worth or value. The procedure involved is as follows:
(i) Determine the Job to be Evaluated
In a large organisation, there are several jobs involving different skills, efforts, working conditions, etc. Therefore, a few benchmark or representative jobs are selected from each job category.
(ii) Select the Factors
The selected jobs are analysed and factors common to all these jobs are identified. The factors choosen for evaluation should be measurable, significant, mutually exclusive and acceptable to both management and workers. The selected factors may be divided into sub-factors as given below:
Factor | Sub-factors |
Skill | Education, experience, training, judgement |
Efforts | Physical and mental |
Responsibility | Qauality of output, raw materials, machinery and equipment, safety of others. |
Working Conditions | Working environment, accidents, hazards, discomfort etc. |
(iii) Define the Factors
The selected factors and sub-factors are defined clearly in writing. This is necessary to ensure that different raters interpret a particular factor in the same way.
(iv) Determine the Degrees
Different degrees of each factor are decided and defined clearly. The same number of degree should be used for each factor so as to ensure consistency. For example, the degrees of ‘education’ may be defined as follows:
Degree | Definition |
1 | Should be able to do ordinary counting and to understand verbal instructions. |
2 | Should be able to read and write. |
3 | Should be able to carry out mathematical calculations. |
4 | Requires ability to compare written material and to make advanced calculations. |
(v) Determine Relative values of Job Factors
The relative value of various factors depends upon their significance to the job. Maximum points for each factor may be as follows:
Factor | Maximum Points |
Skill | 400 |
Effort | 175 |
Responsibility | 300 |
Working Conditions | 125 |
Total | 1,000 |
The total points for a particular factor should be allocated among its subfactors. For instance, the total points for ‘skill’ may be allocated as education 75, experience 125, training 100 and judgement 100.
(vi) Assign Point Values to Degrees
Point values for different degrees of a factor may be decided on the basis of arithmetic progression as shown in the Table.
(vii) Find Point Value of the Job
The various points assigned to different factors in a job are added up to find out the total points which indicate the relative worth of the job.
(viii) Assign Money Values
Once the worth of a job in terms of total points is known these are connected to money values keeping in view the prevailing wage rates. A standard unit of money may be assigned to each point so as to convert point scores into monetary values. This is illustrated in the Table.
Advantages of Point Method
(i) Paint method is the most comprehensive and accurate method of job evaluation. Factors are divided into subfactors and different degrees of a factor are considered.
(ii) Assignment of point scores and money values is consistent thereby minimizing bias and human judgement.
(iii) Systematic wage differentials according to content of the job can be determined.
Disadvantages of Point method
(i) Point method is complicated and an average worker cannot understand it easily.
(ii) It is time-consuming and expensive.
(iii) Errors may occur if assigned point value are not realistic. It is difficult to determine factor levels and assign point values.
(iii) It is difficult to apply this method to managerial jobs wherein the work content is not measurable in quantitative terms.
Advantages of Job Evaluation
- It helps in creating job families by grouping jobs having similar characteristics.
- Job evaluation enables an organization to develop a systematic and scientific basis for the determination of equitable pay and other incentives.
- It provides a clear and objective basis for wage negotiations and collective bargaining.
- Since job evaluation considers the behavioral, motivational and personality requirements of a job in addition to the job characteristics, it provides the basis for determining the career plans and succession plans of the organization.
- It simplifies wage administration by making wage rates more uniform.
- It facilitates better utilization of resources as it reveals jobs which require less or more skilled workers than those already performing jobs.
- It facilitates job redesign by re-allocating the easy and difficult tasks equally among different jobs.
Limitations of Job Evaluation
(i) Job evaluation is not exactly scientific.
(ii) The factors taken by the programme are not exhaustive.
(iii) There may be wide fluctuations in compensable factors in view of change in technology, value and aspirations of employers etc.
(iv) It is not suited to determine the relative worth of managerial jobs as these jobs involve considerable planning, decision making and supervision of others which cannot be measure quantitatively.
(v) Employees, trade union leaders, management and the programme operators may assign different weightage to different factors, thus creating grounds for dispute.
(vi) It is time time consuming and expensive process.
