Project Management Chapter 7
Rough order of magnitude (ROM) estimate
A cost estimate prepared very early in the life of a project to provide a rough idea of what a project will cost
Definitive Estimate
A cost estimate that provides an accurate estimate of project costs
Budgetary estimate
A cost estimate used to allocate money into an organization's budget
Parametric Estimating
A cost estimating technique that uses project characteristics (parameters) in a mathematical model to estimate project costs
Bottom-up estimate
A cost-estimating technique based on estimating individual work items and summing them to get a project total
Analogous Estimates
A cost-estimating technique that uses the actual cost of a previous similar project as the basis for estimating the cost of the current project; also called top-down estimates
Top-down estimates
A cost-estimating technique that uses the actual cost of a previous, similar project as the basis for estimating the cost of the current project; also called analogous estimates
Cash flow analysis
A method for determining the estimated annual costs and benefits for a project
Earned value management (EVM)
A project performance measurement technique that integrates scope, time and cost date
Learning curve theory
A theory that when many items are produced repetitively, the unit cost of those items normally decreases in a regular pattern as more units are produced
Cost baseline
A time-phased budget that project managers use to measure and monitor cost performance
Earned Value (EV)
An estimate of the value of the physical work actually completed
Estimate at completion (EAC)
An estimate of what it will cost to complete the project based on performance to date
Intangible Costs or benefits
Costs or benefits that are difficult to measure in monetary terms
Tangible costs or benefits
Costs or benefits that can be easily measured in dollars
Indirect costs
Costs that are not directly related to the products or services of the project, but are indirectly related to performing the project
Direct costs
Costs that can be directly related to creating the products and services of the project
Management Reserves
Dollar amounts included in a cost estimate to allow for future situations that are unpredictable (sometimes called unknown unknowns)
Unknown unknowns
Dollar amounts included in a cost estimate to allow for future situations that are upredictable (sometimes called management reserves)
Contingency Reserves
Dollar amounts included in a cost estimate to allow for future situations that may be partially planed for (sometimes called know unknowns) and that are included in the project cost baseline
Known unknowns
Dollar amounts included in a cost estimate to allow for future situations that may be partially planned for (sometimes called contingency reserves) and that are included in the project cost baseline
Reserves
Dollar amounts included in a cost estimate to mitigate cost risk by allowing for future situations that are difficult to predict
Sunk cost
Money that has been spent in the past
Profits
Revenues minus expenses
Overrun
The additional percentage or dollar amount by which actual costs exceed estimates
Cost variance (CV)
The earned value minus the actual cost
Schedule Variance (SV)
The earned value minus the planned value
Baseline
The original project plan plus approved changes
Budget at completion (BAC)
The original total budget for a project
Planned Value (PV)
The portion of the approved total cost estimate planned to be spent on an activity during a given period
Project Cost management
The processes required to ensure that the project is completed within the approved budget
Rate of performance (RP)
The ratio of actual work completed to the percentage of work planned to have been completed at any given time during the life of the project or activity
Cost performance index (CPI)
The ratio of earned value to actual cost; can be used to estimate the projected cost to complete the project
Schedule performance index (SPI)
The ratio of earned value to planned value; can be used to estimate the projected time to complete a project
Profit margin
The ration between revenues and profits
Life cycle costing
The total cost of ownership, or development plus support costs, for a project
Actual (AC)
The total of direct and indirect costs incurred in accomplishing work on an activity during a given period
