Human resource management (HRM) involves ensuring an organization has the right employees by managing activities like recruitment, selection, training, and retention. It is critical to an organization's success. The HRM process includes assessing current employees, determining future needs, recruiting to fill vacancies, selecting the best candidates, and providing training and development. Key parts of the process are job analysis to understand positions, developing job descriptions to guide recruiting and selection, using valid and reliable selection procedures to minimize hiring errors, and referring current high-performing employees.
