HR analytics provides valuable insights for organizations by analyzing employee-related data using statistical tools. It has two main components: descriptive analytics which measures past performance, and predictive analytics which provides insights into future outcomes. The increased focus on HR analytics stems from both necessity and opportunity. Necessity arises from the growing importance of human capital to organizational value creation. Opportunity comes from the vast amounts of employee data now available that can be transformed into useful insights using analytics. When done effectively, HR analytics can help organizations improve performance, better link business objectives to workforce strategies, and increase returns on investment in human resources.
