Digitalizing 360 Degree Employee Competency using Banzhaf Power Index and CDF

Abstract

Traditionally, 360 degree evaluation of employee competency has been done using ratings given by Subordinates or Direct Reports, Peers, Manager and Self. Based on the rating by all rating group, the competency of the employee is determined. The gap between self-rating and ratings of all other group determines whether an employee has hidden strength or has blind spot in each competency variable. However, whenever larger number of subordinates or peers rates an employee, there is inherent bias and the employee’s overall competency rating can be low if the larger group holds grudge against the employee. To avoid bias and determine true rating, this paper proposes innovative use of Banzhaf Power Index. The complete computation and digitalization of Banzhaf Power Index for Chennai based Wind Energy Company is carried out and presented in this paper. The interactive Wolfram Computable Document Format (CDF) has also been created for wider use by personnel managers of other companies.
