Manpower planning enables a department to project its short to long term needs on the basis of its departmental plans so that it can adjust its manpower requirements to meet changing priorities. The more changing the environment the department is in, the more the department needs manpower planning to show:
the number of recruits required in a specified timeframe and the availability of talent
early indications of potential recruitment or retention difficulties
surpluses or deficiencies in certain ranks or grades
availability of suitable qualified and experienced successors 8)
