Performance management system
The performance management system is one of the key tasks of HR Management. Now that you are beginning to introduce one, careful thought needs to be given to it. It depends on comprehensive knowledge of the organization, its nature, operations, background, levels of personnel, and the linkage of the PMS with administrative aspects like pay, increment, promotion/demotion, transfer, etc.
Questions to consider
Is this going to be your first year of operation, or is there any such practice in the organization? If yes, what is the feedback about it? There is no standard formula for PMS that fits all categories. You need the services of a consultant to evolve a well-thought-out and effective PMS.
