| At present,China’s social economy is changing from the stage of high-speed growth to the stage of high-quality development and education,and there are higher requirements for quality,which is also a more stringent standard for modern enterprises.Enterprise development for China’s market economy to achieve a comprehensive occupation of the key,one of which is to achieve effective control of project risk management progress management personnel,which is each enterprise in the long-term on-site work ability and project cost management social practice.To control the progress of the project,shorten the time limit or speed up the progress,we must rely on modern management methods and scientific and technological progress to achieve.In concrete engineering construction project risk management process,can according to the actual development of enterprise project characteristics,the use of the computer information network security technology and society,in the management way achieve forecasting,decision-making and management,and the management method of system engineering are emphasized,completes the analysis and combination of qualitative and quantitative,In this way,dynamic management and optimal allocation of resources can be realized,so as to realize the progress control of all kinds of project quality management.Since its establishment,company Z has always been a company mainly engaged in the production of positioning instruments.In recent two years,due to the "chip tide",the chip suppliers in the original products of company Z have stopped supplying.Seeking new chips to promote the use of the company’s products has also become the key work of the company.If the So C platform hardware replacement project cannot be completed as soon as possible,the products of company Z will be out of stock,The originally stable market is easy to be occupied by friends.The current market has evaluated the estimated out of stock time.How to ensure that the project is completed before this time point is the focus of this paper.This paper mainly uses literature analysis and questionnaire survey as research methods.By summing up the factors that may exist before the company’s imperfect project schedule control,the key chain method is adopted to correct and manage the project schedule risk.Decompose the project based on the critical chain method,sort various activities,identify key activities and set the project buffer to realize the effective allocation of resources and ensure the reasonable progress of the project.At the same time,compare the past project management mode of Z company with the key chain mode,The project progress has been effectively improved after the use of key chain technology,so as to determine the advantages and disadvantages of the two,and provide a new direction for the project risk management of the follow-up company. |
