Knowledge points of 2022 system integration project management engineer examination: project cost management

Many candidates are preparing for the exam 2022 System integration project management engineer examination , I have arranged for you 2022 Knowledge points of system integration project management engineer examination ： Project cost management , For everyone to prepare for the exam and review .

Each process of project cost management , Include ：

Planning cost management ： For planning 、 management 、 Spend and control project costs and make policies 、 Procedures and documentation .

Estimated cost ： The process of approximately estimating the amount of money required to complete a project activity .

Budget making ： Aggregate estimated costs for all individual activities or work packages , The process of establishing an approved cost baseline .

Control the cost ： Monitor project status to update project budget 、 The process of managing cost baseline changes .

These processes not only interact with each other , It also interacts with processes in other areas of knowledge .

Earned value technology is needed for each planned activity 、 Work packages or control accounts identify these significant values , namely ：

Planned value （Planned Value,PV）.PV It is to plan to complete an activity or... Before a given time point WBS Budgeted cost of component work .

Earned value （Earned Value,EV）.EV Is the budgeted cost of the work actually completed within a given time period .

actual cost （Actual Cost,AC）.AC Is the actual total cost of actually completing the work within a given time period .

Cost deviation （Cost Variance,CV）.CV be equal to EV reduce AC. The formula is ：CV=EV-AC

Schedule deviation （Schedule Variance,SV）.SV be equal to EV reduce PV. The formula is ：SV=EV-PV

CV and SV It can be converted to reflect the cost and schedule of any project （ The performance of ） Efficiency index of .

Cost execution （ The performance of ） Index （Cost Performance Index,CPI）.CPI be equal to EV and AC The ratio of the .CPI Is the most commonly used cost efficiency indicator . The formula is ：CPI=EV/AC;CPI Value if less than 1 The actual cost exceeds the budget ,CPI If the value is greater than 1 The actual cost is lower than the budget .

Schedule execution （ The performance of ） indicators （Schedule Performance Index,SPI）. Except for progress status ,SPI Also predict the completion date . Sometimes and CPI Used in conjunction to predict project completion estimates .SPI be equal to EV and PV The ratio of the . The formula is ：SPI=EV/PV;SPI Value if less than l The actual progress is behind the planned progress ,SPI If the value is greater than 1 It means that the actual progress is ahead of the planned progress .

Prediction techniques include predicting the time point at that time based on known information and knowledge , Estimate and predict the future situation of the project .

BAC= On completion PV The sum of the

ETC Equal to the revised remaining work estimate determined by the project implementation organization . This estimate takes into account resource performance and productivity to date , It is a relatively accurate comprehensive estimation . There are two ways to calculate ETC：

Based on atypical deviations （ The current bias is seen as atypical , And the project team does not expect this kind of deviation in the future ） Calculation ETC.

ETC=（BAC-EV）

Based on typical deviations （ The current deviation is considered to represent the future deviation ） Calculation ETC.

ETC=（BAC-EV）/CPl

EAC It is the most likely overall estimate based on project performance and qualitative risk analysis .EAC When the work of a given project is completed , Plan activities 、WBS Expected or foreseeable final total estimate of the component or project .EAC Equal to the actual cost to date （AC） Add new... Provided by the implementing organization ETC.EAC Calculation formula ：

EAC=AC+ETC

Completion performance index （To Complete Performance Index,TCPI） Represents the work value corresponding to the remaining budget per unit cost , The formula is ：

TCPI=（BAC-EV）／（BAC-AC） or TCPI=（BAC-EV）/（EAC-AC）
