According to Human resource management,one of the most important HRM gurus is Peter Drucker.It states that successful leaders should put people and business ethics as a priority rather than focusing entirely on profits and rigid rules and work structures. The pillars of Drucker’s theory of management are decentralization, prioritization of knowledge work, management by objectives, and SMART goals. By implementing Drucker’s approach, managers can empower their employees, improve the company’s culture, encourage innovation, increase efficiency, create a nurturing and ethical working environment, and ultimately boost the business’s success.
