Cost management is to use the project cost plan to measure the actual economic achievements of the project. The project cost management finds out the cost deviation value through the dynamic analysis method, and checks the actual implementation of the cost, through the effective correction method, so that the project cost can be completed smoothly. Cost management mainly includes comparing the difference between cost plan and actual cost in real time, analyzing and finding out the cause of deviation, recording the change of cost plan in project cost, preventing unreasonable project cost plan from being in cost budget and informing the project management personnel of the change result.
