Dear Nisha,
HR plays the most important role of an enabler and coordinator as far as Performance Appraisal (PA) is concerned. This role has multiple parts, namely educating both appraiser and appraisee on the process of PA, ensuring that at all levels and across the organizations the PA timetable is adhered to, communicating and documenting the records to all concerned, and also ensuring that actions on performance enhancement are planned and implemented through appropriate interventions. This ensures that the PA, as an integral part of the strategic HR process, develops capabilities to address the future needs of the organization within a rapidly changing environment.
For more clarifications, you may write to me.
Regards,
Sanjay
