Good Day,
Below is the definition--hope it will help.
Human Resource management - Human resource management is concerned with the development and implementation of people strategies, which are integrated with corporate strategies, and ensures that the culture, values and structure of the organization, and the quality, motivation and commitment of its members contribute fully to the achievement of its goals.
HRM is concerned with carrying out the SAME functional activities traditionally performed by the personnel function, such as HR planning, job analysis, recruitment and selection, employee relations, performance management, employee appraisals, compensation management, training and development etc. But, the HRM approach performs these functions in a qualitatively DISTICNT way, when compared with Personnel Management.
