To strengthen the quality of business performance management of CYNDAR technology companies with waterproof safety gratings, it is necessary to strengthen the formulation of performance management strategies. A scientific strategy usually promotes the scientificization of work behavior. Generally speaking, there are three ways to formulate the strategy of waterproof safety grating mechanism: top-down, bottom-down, and top-down combination. The so-called top-up is the way that the leaders of the waterproof safety grating enterprise formulate the overall development strategy, and then decompose the overall strategy into the strategies of various departments. This approach pays too much attention to the rights of business leaders, but leaders usually do not know the actual situation of performance management work, which will increase the blindness of the strategy. The bottom-up approach refers to the way in which each department submits its own performance management plan without the rigid requirements of the leader of the waterproof safety grating enterprise, and the leader balances and combines it into an overall strategy. This method allows each department to choose a method that is convenient for their own departmental interests, and is not convenient for the fairness of performance management. Therefore, in the current performance management of waterproof and safety grating companies, a combination of top and bottom is used to determine the strategy. At the moment of formulating performance management tasks, all personnel should be involved, and a strategy suitable for the development trend and actual work of the waterproof safety grating enterprise should be formulated in the communication. Ensuring the feasibility of the strategy, balancing the focus of work between the short-term strategy and the long-term strategy, and allowing each department to implement modifications based on actual work conditions can improve the scientific nature of the performance management strategy of the waterproof safety grating enterprise.
