Chapter 7: Project Cost Management Flashcards
BAC
Budget at Completion
Abbreviations: BAC
Definition: The sum of all budgets established
for the work to be performed.
Usage: The value of total planned work, the
project cost baseline.
Earned Value
Abbreviation: EV
Definition: The measure of work performed
expressed in terms of the budget authorized for that work.
Use: The planned value of all the work completed (earned) to a point in time, usually the data date, without reference to actual costs.
Equation:
EV = Sum of the planned value of completed work
EV = Percentage completed * BAC
Present Value
PV = Percentage Planned * BAC
Cost Variance
Abbreviations: CV
Definition: The amount of budget deficit or surplus at a given point in time, expressed as the difference between the earned value and the actual cost.
Usage: The difference between the value of
work completed to a point in time, usually the data date, and the actual costs to the same point in time.
Equation: CV = EV – AC
Interpretation:
Positive = Under planned cost
Neutral = On planned cost
Negative = Over planned cost
Schedule Variance
Abbreviations: SV
Definition: The amount by which the project is ahead or behind the planned delivery date, at a given point in time, expressed as the difference between the earned value and the planned value.
Usage: The difference between the work completed to a point in time, usually the data date, and the work planned to be completed to the same point in time.
Equation: SV = EV – PV
Interpretation:
Positive = Ahead of Schedule Neutral = On schedule Negative = Behind Schedule
Cost Performance Index
Abbreviations: CPI
Definition: A measure of the cost efficiency of
budgeted resources expressed as the ratio of earned value to actual cost.
Usage: A CPI of 1.0 means the project is exactly on budget, that the work actually done so far is exactly the same as the cost so far. Other values show the percentage of how much
costs are over or under the budgeted amount for work accomplished.
Equation: CPI = EV/AC
Interpretation:
Greater than 1.0 = Under planned cost
Exactly 1.0 = On planned cost
Less than 1.0 = Over planned cost
Schedule Performance Index
Abbreviations: SPI
Definition: A measure of schedule efficiency expressed as the ratio of earned value to planned value.
Usage: An SPI of 1.0 means that the project is exactly on schedule, that the work actually done so far is exactly the same as the work planned to be done so far. Other values show the percentage of how much costs are over or under the budgeted amount for work planned.
Equation: SPI = EV/PV
Interpretation:
Greater than 1.0 = Ahead of schedule
Exactly 1.0 = On schedule
Less than 1.0 = Behind schedule
Estimate to Complete
Abbreviations: ETC
Definition: The expected cost to finish all the
remaining project work.
Usage: Assuming work is proceeding on
plan, the cost of completing the remaining authorized work can be calculated using:
Equation: ETC = EAC – AC
To-Complete Performance Index (BAC)
Abbreviations: TCPI
Definition: A measure of the cost performance that must be achieved with the remaining resources in order to meet a specified management goal, expressed as the ratio of the cost to finish the outstanding work to the budget available.
Usage: The efficiency that must be maintained in order to complete on
plan.
Equation: TCPI = (BAC – EV)/(BAC – AC)
Interpretation:
Greater than 1.0 = Harder to complete
Exactly 1.0 = Same to complete
Less than 1.0 = Easier to complete
Plan Cost Management
It is the process of defining how the project costs will be estimated, budgeted, managed, monitored and controlled
Cost Management Plan
It is a component of the project management plan and describes how the poject costs will be planned, structured and controlled
The cost management plan dictates how cost variances will be managed.
Level of precision
The degree to which cost estimates will be rounded up or down
Estimate Costs
It is the process of developing an approximation of the cost of resource needed to complete project work
Determine Budget
It is the process of aggregating the estimated costs of individual activities or work packages to establish an authorized cost baseline.
Control Costs
It is the process of monitoring the status of the project to update the project costs and managing changes to the cost baseline
Earned Value Anaylsis
It compares the performance measurement baseline to the actual schedule and cost performance. It monitors 1. Planned Value 2. Earned Value 3. Actual Cost
Variance at Completion
Abbreviations: VAC
Definition: A projection of the amount of budget
deficit or surplus, expressed as the difference between the budget at completion and the estimate at completion.
Usage: The estimated difference in cost at the completion of the project
Equation: VAC = BAC – EAC
Interpretation:
Positive = Under planned cost
Neutral = On planned cost
Negative = Over planned cost
Estimate at Completion
Abbreviations: EAC
Definition: The expected total cost of completing all work expressed as the
sum of the actual cost to date and the estimate to complete.
Usage: If the CPI is expected to be the same for the remainder of the project, EAC
can be calculated using:
Equation: EAC = BAC/CPI
Interpretation:
Planned Value
Abbreviation: PV
Definition: The authorized budget assigned to scheduled work.
Use: The value of the work planned to be completed to a point in time, usually the data date, or project completion.
Actual Cost
Abbreviations: AC
Definition: The realized cost incurred for the
work performed on an activity during
a specific time period.
Usage: The actual cost of all the work
completed to a point in time, usually
the data date.
