Human resource planning is a process of forecasting future personnel needs and the availability of personnel to meet those needs in order to ensure that the right number and type of people are available at the right time and place. It involves forecasting demand and supply of personnel, developing programs to fulfill needs, implementing those programs, and evaluating their effectiveness. Effective HRP requires aligning HR strategies with organizational objectives, obtaining management support, maintaining accurate personnel records, using appropriate forecasting techniques, and revising plans and processes over time.
