Alternate ranking is the performance appraisal method for employees where assessor selects the best and worst employees based on certain trait/criterion and ranks them accordingly. First, all employees involved in ranking are listed. Then based on the established trait/criterion, assessor selects best employee and puts him/her at the top of the ranking. Later, assessor selects the employee whose performance is least and ranks him/her as the last. The employees who are assessed as second highest and second last are added again to the rank list from top and bottom. This alternating ranking of highest and lowest, continues until all employees are ranked.
Consider a company ABC. Let 12 employees be working in sales department in its Delhi branch. Now, Mr. Nanda Kishore who is HR Manager of branch, decides to do performance appraisal for his employees. He decides to adopt Alternate Ranking Method and keeps sales target achievement as the criterion of ranking. On the basis of assumed criterion, following are the percentage of sales target achieved by employees:
Sales target achievement in percentage
So, now according to Alternate Ranking Method, first best employee is selected and given rank 1. Here we can see employee 5 has highest sales target achievement, so he is given rank 1 whereas employee 3 with only 67% of sales target achievement is given last rank. Now we are left with 10 employees. Again, we can see that employee 7 is with highest target achievement and hence given rank 2 (after employee 5) whereas employee 9 is given second last rank. Similar process is carried out for all employees and are ranked accordingly.
Following table shows the ranking order done according to Alternate Ranking Method.
