The principle of Taylor's scientific management are as follows:

1. Science, not a rule of thumb: The first principle of the scientific management aims to adopt the scientific way of management rather than the rule of thumb approach. So this principle suggests there must be scientific analysis and study of any job and only after the investigation, an action should be conducted.  The decision should be made on the basis of facts, not on the basis of opinions and beliefs.
   
   
2. Harmony, not discord: In the process a management there is a relationship between a manager and an employee. There will be a personal interest of the employee and there will be organizational interest. So this principle states that both this interest should go side by side. There must be a harmony of interest. It should be focused towards attaining the organizational goals with mutual benefit of both the employee and the organization.
   
   
3. Co-operation, not individualism: According to this principle there should be a feeling of co-operation between the manager and the labor. It requires the change of mental attitudes and the change of management towards each other. When there is co-operation between them, the size of profit will increase and the is no chance to quarrel about the distribution of profits.
   
   
4. Maximum output: According to this principle, a business organization must always be focused towards maximizing the profit and productivity. There should be an optimum utilization of resources. maximum output and optimum utilization of resources will bring higher profit for the employer and better wages and salaries for the employees.
   
   
5. Division of responsibility: This principle divides the role of planning and executing among the employer and the employee. The employer should be given the role of only planning and the employee should focus on only operating to execute the plans due to this there will be no confusion regarding their roles and there will be a smooth operation of action. 
   
   
6. Development of employees: According to Taylor, there must be a scientific selection of human resources and once they are selected they must be trained and developed in such a way that they can work to their maximum capacity for the organization. Trained employees increase their satisfaction and increases the productivity.
