To successfully manage human resources, individuals need personal credibility, business knowledge, understanding of the business strategy, technology knowledge, and the ability to deliver HR services. Human resource management practices should be evidence- based, that is, based on data showing the relationship between the practice and business outcomes related to key company stakeholders (customers, shareholders, employees, community). In addition to contributing to a company’s business strategy, human resource practices are important for helping companies deal with sustainability, globalization, and technology challenges. Global challenges include entering international markets, immigration, and offshoring. Technology challenges include using new technologies to support flexible and virtual work arrangements, high-performance work systems, and developing effective e-HRM practices and human resource information systems.
