What problems do you face during manpower planning?

Manpower planning is not always successful. It faces many problems. There is generally identity crisis in which managers as well as human resource specialists do not fully understand the total human resource planning. Manpower planning fails many times because of lack of sufficient initial effort. Human resource planning must be based on organizational objectives and plans. It requires development of good communication channels between organization planners and the human resource planners. But this communication is lacking and the human resource plans are prepared in isolation of the fundamental organizational plans. To be effective, in the long run, human resource planning must have full support to top management.
