What is human resources?
Human resources is the term — first used in the early 1900s and then more widely in the 1960s — for the people who work for the organization, in aggregate.
HRM is really employee management with an emphasis on those employees as assets of the business. In this context, employees are sometimes referred to as human capital. As with other business assets, the goal is to make effective use of employees, reducing risk and maximizing return on investment (ROI).
The modern HR technology term, human capital management (HCM), has come into more frequent use than the term, HRM, with the widespread adoption by large and midsize companies and other organizations of software to manage many HR functions.
