Introduction Effective Management theories form a basis for a successful business management. Managers in different organization situation can incorporate the already designed and tested management practices to add value and satisfaction to their management styles in the organization they lead. Mary Parker Follet is one of the pioneer women to contribute to the management practices that modern managers embrace in managing the organizations. Follett’s management practices stressed on the importance of manager’s fixing common goals for its employees. In most of her work, she concentrated on management practices anchored on leadership, power and ethics. She encouraged managers to engage employees in decision making in the organization, thus; guaranteeing a favorable working environment. This paper discusses the major contributions of Follet to management practices and how the twenty first century managers can succeed in embracing them. More specifically, the paper explores the ethics, power and leadership practices connected to her management philosophy and how this management philosophy has continued add value to the contemporary managers. Discussion Ethics is essential in everyday life. Every person who ought to succeed needs to have ethics which is in tandem with the society’s needs. According to Aupperle (2007) ethics cannot be substituted with a technical knowledge. Ethics involves having a “gift” while dealing with people (Follet, 1940) and this feature emanates from the personal qualities of a manager. Follet argues that this gift is not a matter of technique, but managers can acquire it through practice and practical knowledge. Follet also notes that an ethical manager values management as a profession. According to her personal experience, she notes that, in 1920’s, she was one of those people who upheld that management should be recognized as a profession. At the time, the society considered professionals in the field of healthcare and architecture as professionals. This was because they were guided by their service, performance and standards. On the other hand, managers were not valued as professionals (Stivers, 1996). Modern managers can incorporate the ethical management principles in their management practices brought up by Follet. This is important for various reasons. First, it is important for personal improvement because it contributes to the enrichment of life. Second, a manager having good ethics stimulates employees. This encourages an employee in doing the job with satisfaction with a sense of service (Follet, 1940, p.135). Thirdly, ethics contributes to the integrity of a manager, thus having a sense of control and respect while executing his or responsibilities in the organization. Integrity can refer to standards, codes of conduct and thus translates to honest work. And lastly, ethics makes a manager to feel more loyal to his or her profession than to the company. When managers embrace ethics, they encourage commitment and productivity to their work. According to Stivers (1996) organization ethics entails the ethical element of the organization structure and the ethical appraisal of the organizations incentives. Hence, these tenets affect the behavior of the employees in an organization. Thus, power plays a central role in harmonizing these elements
