Human resource management involves recruiting, hiring, deploying, and managing employees. It includes functions like recruiting, compensation, training, labor relations, and organizational development. Traditionally, HRM involved time wasted on lengthy and unproductive tasks with vast amounts of data. Microsoft Excel can help simplify HRM tasks through functions like VLOOKUP, SUMIF, SUM, and pivot tables which allow arrangement of employee data, maintenance of salary sheets, creation of understandable summaries, and analysis of employee distribution and origins.
