Human resource planning (HRP) involves forecasting future personnel needs and the availability of qualified employees. It ensures the right number and types of employees are available at the right time and place. The HRP process includes forecasting demand and supply of personnel, identifying gaps, and developing programs to address surpluses or shortages through actions like recruiting, training, reassignment, or layoffs. Effective HRP is based on organizational objectives and requires support from top management with accurate personnel data and appropriate forecasting techniques.
