HR operating models serve as the blueprint for HR service delivery, enabling organizations to optimize resources, enhance efficiency, and foster a culture of continuous improvement. The concept of HR operating models has undergone a remarkable transformation over the years. Initially, HR functions were primarily focused on administrative tasks, such as payroll processing and record-keeping. 

Over time, as organizations recognized the strategic importance of human capital, HR's role expanded to encompass talent acquisition, employee development, and fostering a positive workplace culture.
