This document discusses several models of human resource management (HRM), including the Harvard model developed in 1984, the Michigan model, and the strategic HRM model. The Harvard model focuses on employee commitment rather than control and sees HRM as a strategic partner aligned with business objectives. It evaluates HR policies based on their impact at the individual, organizational and societal levels. The Michigan model emphasizes matching the right people to the right jobs and using selection, appraisal and rewards to increase organizational effectiveness. The strategic HRM model aims to attract, retain and develop employees through financial and non-financial rewards in order to improve efficiency, adaptability and performance.
