Dear Nidhi,
We can have the Key Result Areas (KRAs) or the Key Performance Areas (KPAs) for each person under one department and set points for each. The head of the department can be asked to review and assign points that the employee may have gained against each KPA. Accordingly, the person receiving lower or equal to 2 (on a 5-point scale) may require training in that specific competency (e.g., communication) for which they are scoring lower points in KPAs.
Regards, Monalisa HR
