Enterprises can strengthen cost and cost controls and formulate clear standards for cost and cost control. Enterprise cost management mainly takes measures to reduce resources by analyzing cost-forming factors in the entire production process of products, strictly supervising established cost control standards, and correcting deviations in a timely manner. The consumption and expenditure of R&D and production links of manufacturing companies are controlled within the specified range [2]. Companies can formulate cost and cost criteria using the following methods: 1) Using the exponential decomposition method, the exponential decomposition method can be divided by zero, and the large index of a price firm can be divided into several smaller indices. More specifically, it performs cost management tasks and can be broken down by department or according to the product's process stage or production process. 2) The Budget Act establishes cost and cost control standards, and manufacturing companies can formulate short-term expense budgets based on quarterly production and sales plans and use them as cost control standards. Should pay attention to The company's budget.
