Project Cost Flashcards
The actual amount of monies the project has spent to date.
Actual Cost (AC)
An approach that relies on historical information to predict the cost of the current project.
It is also known as top-down estimating and is the least reliable of all the cost-estimating approaches.
Analogous Estimating
An estimating approach that starts from the zero, accounts for each component of the WBS, and arrives at a sum for the project.
It is completed with the project team and can be one of the most time-consuming and most reliable methods to predict project costs.
Bottom-Up Estimating
This estimate is also somewhat broad and is used early in the planning processes and also in top-down estimates.
The range of variance for the estimate can be from -10 percent to +25 percent.
Budget Estimate
A cost-estimating approach that uses a database, typically software-driven, to create the cost estimate for a project.
Commercial Database
A contingency allowance to account for overruns in costs.
Contingency allowances are used at the project manager’s discretion and with management’s approval to counteract cost overruns for scheduled activities and risk events.
Contingency Reserve
Costs are parallel to each WBS work package.
The costs of each work package are aggregated to their corresponding control accounts.
Each control account then is aggregated to the sum of the project costs.
Cost Aggregation
A time-lapse exposure of when the project monies are to be spent in relation to cumulative values of the work completed in the project.
Cost Baseline
The cost aggregation achieved by assigning specific dollar amounts for each of the scheduled activities or, more likely, for each of the work packages in the WBS.
Cost budgeting applies the cost estimates over time.
Cost Budgeting
A system that examines any changes associated with scope changes, the cost of materials, and the cost of any other resources, and the associated impact on the overall project cost.
Cost Change Control System
The cost management plan dictates how cost variances will be managed.
Cost Management Plan
The monies spent to recover from not adhering to the expected level of quality.
Examples may include rework, defect repair, loss of life or limb because safety precautions were not taken, loss of sales, and loss of customers.
This is also known as the cost of nonconformance to quality.
Cost of Poor Quality
The monies spent to attain the expected level of quality within a project.
Examples include training, testing, and safety precautions.
Cost of Quality
Measures the project based on its financial performance.
The formula is CPI = EV/AC
Where EV is Earned Value and AC is Actual Cost
Cost Performance Index (CPI)
The difference of the earned value amount and the cumulative actual costs of the project.
The formula is CV = EV - AC
Where EV is Earned Value and AC is Actual Cost.
Cost Variance (CV)
This estimate type is one of the most accurate.
It’s used late in the planning processes and is associated with the bottom-up estimating.
You need the WBS in order to create the definitive estimate.
The range of variance for the estimate can be from -5 percent to +10 percent.
