This study aims to explore the extent of usage of a Human Resource Information System (HRIS) in mid to large sized organizations and the advantages they derive from the implementation of the same in the Human Resource Planning (HRP) sub-functions. Most medium and large scale organisations spend large amounts of money and reserves on HR software, but unfortunately many of them utilise it only for HR administrative purposes rather than for effective and efficient human resource planning (true HRP). The role of HRM has changed altogether from a traditional (popularly called personnel management) to a strategic one.
