Toyota is still profitable while maintaining its price for more than 10 years because it minimizes costs through lean management. Everyone knows that profit = selling price – cost. Cost must be reduced to make profit while selling price is constant. Cost of raw materials, wages, energy costs, and equipment depreciation should be said to be the same for different companies produce same amount of same product. However, different production modes, for example, inattentive quality control of Company A leads to frequent repairs and consumption of excess materials, uneven production of Company B leads to increase of overtime pay, cause different waste of cost. Improvement and metronomic management must be conducted in order to reduce costs and increase profits. There are two improvements, namely, top-down change and bottom-up revolution. All levels of management, especially the top management must have the determination and perseverance to make changes for whichever improvement. It is necessary to guide and motivate employees effectively and reasonably because employees are accustomed to previous work methods and ways, which are different to change. Therefore, formulation and refinement of normative documents such as work instructions and standard books is the first step in implementation of lean management, and it is also a priority among priorities. Beat refers to the time value in which a piece or a part produced in a few minutes. Production time and running time determine working time. Consistency of beats of each workshop and process is related to the balance and maximization of production efficiency. Just like a bucket, the shortest plank determines the amount of water in the bucket. Five indicators of people, machines, materials, laws and rings involved in lean management, among which indicator of people is ranked first.
