Hi Sandy,
Manpower planning is directly proportional to the corporate objectives. In every organization, there are organizational objectives as well as departmental objectives. To meet these objectives, managers need effective planning. Managers must anticipate future business needs and make timely and informed decisions aligned with company objectives, policies, and cost performance. Manpower planning encompasses various aspects such as staffing functions, recruitment, selection, training, demotion, and promotion.
Manpower planning includes the creation of a Manpower Plan, job descriptions of employees, and sources of manpower. These sources can be internal, such as promotions, or external, involving recruitment through various channels.
I hope this information is helpful to you.
