This document discusses techniques for forecasting human resource demand. It describes forecasting as projecting future HR needs under assumptions about organizational policies and the environment. The techniques discussed include managerial judgment, ratio-trend analysis, work study, and the Delphi technique. Managerial judgment involves top-down and bottom-up approaches while ratio-trend analysis uses historical ratios of production levels to workers. Work study calculates workload and workforce needs based on standard hours per unit. The Delphi technique integrates independent expert opinions to predict the future without direct confrontation.
