Manpower planning, also called human resource planning, involves analyzing current staffing levels, forecasting future needs, and developing employment programs to ensure the right number and type of employees are available at the right time. It is a systematic process that helps organizations efficiently utilize personnel, improve productivity and human relations, and support managerial functions like planning and controlling. Conducting manpower planning allows companies to identify staffing shortages or surpluses and take corrective actions, while reducing costs and developing talent through targeted training.
