project cost management
process
Cost Estimate
step
Identify and analyze cost components
Estimate the cost of each account based on the identified project cost components.
Comment on cost estimate results
method
analogy estimation method
top-down estimation method
bottom-up estimation method
Parametric model estimation method
cost budget
Allocate estimated total costs to various project work items and establish a cost baseline plan to measure project performance
step
Allocate the total project cost to the various work packages of the WBS
Redistribute the costs allocated to each work package to the activities included in it
Determine the time plan for each cost budget expenditure and the cumulative budget cost corresponding to each time point, and formulate a project cost budget plan
Cost Control
Ensure that all tasks are carried out within their respective budgets
main content
Influence factors that cause cost baseline changes
Ensure change requests are approved
When changes occur, manage the actual changes
Monitor cost execution and identify deviations from cost baselines
Accurately record all deviations from the cost baseline
Prevent incorrect, inappropriate or unapproved changes from being included in cost or resource usage reports
Notify project stakeholders of approved changes
Take steps to keep overdue cost overruns within acceptable limits
Related terms
life cycle cost
Development costs Maintenance costs
Variable costs (variable costs)
Costs (such as raw materials, labor, fuel) that vary with production volume, workload, or time
fixed costs
It does not change with the production volume, workload and time. Fixed costs are mostly indirect costs. (Such as salary, fixed taxes, depreciation of fixed assets, maintenance fees, office expenses)
direct cost
All expenses that can be directly included in the cost of the product (raw materials constituting the product, wages of production workers)
s
management reserve
Costs are planned separately and are ready for use when unforeseen events occur in the future. Reduce the risk of deviation from cost or schedule targets
cost basis
The approved time-based cost expenditure plan, which reflects approved project cost changes at any time, is used to measure and monitor the actual execution costs of the project.
Common methods
earned value analysis
A project performance measurement method used primarily for performance measurement of actual costs.
By measuring and calculating the budgeted cost of completed work and the actual cost of completed work, and comparing it with the budgeted cost of planned work to obtain the cost deviation, the purpose is to judge the project cost and schedule execution.
three parameters
Budgeted cost of planned workload (BCWS, PV)
Actual cost of work performed (ACWP, AV)
Budgeted cost of work performed (BCWP, EV)
Mnemonic method: A stands for actual, B stands for budget, S stands for plan, P stands for completed, and C stands for cost.
four indicators
cost deviation
CV=EV-AC
CV>0 means that the actual cost of the completed work is lower than the budgeted cost
progress deviation
SV=EV-PV
SV>0 means that the progress is ahead of schedule and the actual execution cost is less than planned.
Cost Performance Index (CPI)
CPI=BCWP/ACWP
CPI<1 means that the actual cost of the completed work is higher than the budgeted cost
CPI>1 means that the actual cost of the completed work is lower than the budgeted cost
Schedule Performance Index (SPI)
SPI=BCWP/BCWS
SPI<1 means progress is delayed and the actual progress is slower than the planned progress.
Mnemonic method
The calculation formulas for CV and SV are BCWP first, CPI and SPI at the top (numerator)
If CV and SV are less than 0, it means a bad situation
If SPI and CPI are less than 1, it means a bad situation

Completion Budget BAC
Estimated Cost of Remaining Work ETC
Atypical deviation calculation ETC=BAC-EV
Typical deviation calculation ETC=(BAC-EV)/CPI
Mnemonic: Atypical means that the estimated cost of the remaining work is correct. Typical means that the estimated cost of the unfinished work will deviate by the same proportion as the work that has been completed.
Estimate EAC at completion
EAC = AV ETC
EAC=BACAV-EV
Mnemonic: The completion estimate is equal to the budget plus the actual additional cost for the current amount of work completed.
