The Scientific Management School and the Human Behavior School highlight fundamentals of communication within an organization. The Scientific Management School emphasizes chains of command, division of labor, and organizational design by assuming that organizations can be developed and designed rationally. Fredrick Taylor stated four essential elements, namely selecting workers carefully, training the worker scientifically, dividing the work equally between the management and workers, and inventing new scientific work methods. Henri Fayol further subdivided the principles into the following fourteen features: discipline, remuneration, scalar chain, equity, centralization, and initiative. The other theorist was Max Weber, who highlighted the principles of bureaucracy. He stated three types of authority which are traditional, charismatic, and bureaucratic.
On the other hand, Human Behavior School emphasizes interpersonal skills, satisfaction, participation, and cooperation. Mary Parker Follett developed foundational principles for the steady and ordered progress of human beings for their well-being based on coordination. Elton Mayo created the Hawthorne effect, which showed that unexpected favors interacted with physical factors affecting the output. The research showed that organizational design alone was insufficient and that human interaction was equally meaningful. Rensis Likert developed a participative management approach that provided insight into employee-centered management to create functional groups linked structurally in an organization.
Both schools have a significant number of communication implications for an organization. In the Scientific Management School, communication was a tool for training employees and issuing daily instructions. It was mainly vertical from the management to the subordinates and was used to reduce uncertainty about measurement and job expectations. Its functional approach was to organize duties and explain the rules and regulations in an organization. Communication implications in Human Behavior theories include discovering that impacted human behavior and the interactions were positive and extensive following cooperation among the workers. Its functional approach was that the relationship aspect between individuals was crucial, and its role was more complex than the Scientific Management theorists stated.
