The Price Efficiency Index (CPI) is an important metric in challenge administration used to measure the price effectivity of a challenge. It is calculated by dividing the Earned Worth (EV) by the Precise Price (AC). The Earned Worth represents the budgeted value of labor carried out, whereas the Precise Price displays the precise bills incurred for that work. For instance, if a challenge has an Earned Worth of $10,000 and an Precise Price of $8,000, the CPI can be 1.25, indicating the challenge is receiving $1.25 value of labor for each greenback spent.
Monitoring this metric supplies worthwhile insights into challenge monetary well being and predicts potential funds overruns or underutilization of assets. A CPI higher than 1 signifies the challenge is beneath funds, whereas a CPI lower than 1 suggests a value overrun. Constant monitoring permits challenge managers to take corrective actions, alter budgets, or reallocate assets as wanted.
