Human resources planning identifies current and future human resource needs to achieve organizational goals. It should link to the overall strategic plan. An aging workforce and demands for qualified workers underscore the importance of effective planning. Planning includes creating strategies for recruitment, retention, flexibility, talent management, and absence management. Best practices define needed human resources to achieve goals, including numbers, competencies, and timing. Competency-based management assesses gaps between current and needed capacities, and designs programs to close gaps like hiring, learning, and succession. Planning is ongoing to best use an organization's human resources by ensuring fit between employees and jobs while avoiding shortages or surpluses.
