Section 1 Summarization of Cost Plan and Control Meanings of cost plan and cost control Cost Plan It refers to a process in which the overall project was break down into each unit or work package and each of their cost is estimated respectively. It adds cost information and schedule information together. Projects overall cost equals to the summation of each work packages cost happened at some certain time. Cost performance depends on time schedule and quantity schedule. Section 1 Summarization of Cost Plan and Control Meanings of cost plan and cost control Cost Control It refers to the process which is used to ensure the implementation of the set cost limitation in cost plan. Its main steps include: Supervising the actual cost according to the cost limitation Identifying any possible variance Finding the reasons caused these variances Adopting suitable correcting behaviours Ensuring these correct behaviours can solve variances issues through supervision Adopting further necessary correcting behaviours Section 1 Summarization of Cost Plan and Control Meanings of cost plan and cost control Cost Plan and Control as Management Functions Cost control and time control need to establish cost objective, and we should use variance analysis to determine the approaching degree of the actual performance and planned performance. Some certain cost variances may exist in all projects. The project manager should check the cost variance table,estimate work packages schedule , related levels risks, establish reasonable and controllable plan for cost supervision. Cost control is a kind of art, rather than science.Thats mainly because its complicated factor-time lag. Section 1 Summarization of Cost Plan and Control Establishing Cost Plan and Control System Preconditons of establishing system The project schedule arrangement must be correct. The evaluation system must be reliable. Project work scope must be clear. Budget must conform to reality. The budget system must be clear.
