Earned value management is a project management technique for measuring project performance and progress. It has the ability to combine measurements of the project management triangle: scope, time, and costs. In a single integrated system, EVM is able to provide accurate forecasts of project performance problems, which is an important aspect of ...
A cost-performance ratio with a positive value (i.e. greater than 1) indicates that costs are running under budget. A negative value (i.e. less than 1) indicates that costs are running over budget. However, a neutral cost-performance ratio (between 1.0 and 1.9) could suggest a certain degree of stagnation in the budget.
Budgeted cost of work performed (BCWP) also called earned value (EV), is the budgeted cost of work that has actually been performed in carrying out a scheduled task during a specific time period. The BCWP is the sum of the budgets for completed work packages and completed portions of open work packages, plus the applicable portion of the ...
The reason to calculate PTA is that when executing the contract, actual cost is the only finance measurement. Compare this measurement with the cost base line to calculate Cost Performance Index (CPI), then we can estimate ( forecast ) the cost at Completion ('EAC' – Estimate at Completion – according to PMBOK , or 'FAC' – Forecast at ...
The Lerner index is defined by: where P is the market price set by the firm and MC is the firm's marginal cost. The index ranges from 0 to 1. A perfectly competitive firm charges P = MC, L = 0; such a firm has no market power. An oligopolist or monopolist charges P > MC, so its index is L > 0, but the extent of its markup depends on the ...
Return on investment. Return on investment ( ROI) or return on costs ( ROC) is the ratio between net income (over a period) and investment (costs resulting from an investment of some resources at a point in time). A high ROI means the investment's gains compare favourably to its cost. As a performance measure, ROI is used to evaluate the ...
Devaux's Index of Project Performance (usually known as the DIPP) is a project management performance metric [1] formulated by Stephen Devaux as part of the total project control (TPC) approach to project and program value analysis. It is an index that integrates the three variables of a project (scope, time and cost) into a single value-based ...
Price index. A price index ( plural: "price indices" or "price indexes") is a normalized average (typically a weighted average) of price relatives for a given class of goods or services in a given region, during a given interval of time. It is a statistic designed to help to compare how these price relatives, taken as a whole, differ between ...
