To-Complete Performance Index (TCPI).

Source: R/evm.R
tcpi.Rd

Calculates the To-Complete Performance Index (TCPI), which indicates the cost performance required on remaining work to meet a target (BAC or EAC). TCPI > 1 means efficiency must improve; TCPI < 1 means efficiency can decrease.

Usage

tcpi(bac, ev, ac, target = "bac", eac = NULL)

Arguments

bac

Budget at Completion (BAC) (total planned budget).

ev

Earned Value.

ac

Actual Cost.

target

The target to calculate TCPI against. Either "bac" (default) to meet original budget, or "eac" to meet revised estimate. If "eac", the eac parameter must be provided.

eac

Estimate at Completion. Required when target = "eac".

Value

The function returns the To-Complete Performance Index (TCPI).

Examples

bac <- 100000
ev <- 35000
ac <- 63000

# TCPI to complete within original budget
tcpi_bac <- tcpi(bac, ev, ac)
cat("TCPI (to meet BAC):", round(tcpi_bac, 2), "\n")
#> TCPI (to meet BAC): 1.76 

# TCPI to complete within revised estimate
eac <- 120482
tcpi_eac <- tcpi(bac, ev, ac, target = "eac", eac = eac)
cat("TCPI (to meet EAC):", round(tcpi_eac, 2), "\n")
#> TCPI (to meet EAC): 1.13
