Assigning weight to each KRA is the prerogative of the HOD or the Departmental Manager. However, this activity has to be done before the commencement of each performance cycle. If the performance cycle is of a quarter or half-year, raising fresh KRA sheet becomes easy. However, if the performance cycle of a year, then the problem of this kind arises.
Due to market conditions or business requirements, if it is required to change the weights assigned to the KRAs or add/delete some KRA, then complete the PA process for a quarter or half-year as the case may be and raise fresh KRA sheet for the remaining part of the year.
