What are the reasons for the change from traditional personnel management to modern human resource management

Traditional personnel management tends to be transactional, operational level affairs. Modern human resource management needs to be the starting point for the strategic objectives of the enterprise, the need to do a good job according to the company's strategy for human development and reserves. Personally believe that the reason for the change is due to the change of the times, and now the competition is the competition for talent, transactional work is increasingly being replaced by a variety of systems and tools, but how to find the right talent for the enterprise to create a good platform for the development of people to make the best use of their talents need to stand on a higher level of consideration, and also need to be more capable of human resources managers.
