EVM and ES terminology

Table 1

The second table breaks down the ES terminology to measures, indicators, and predictors. The terminology depicted in this table has a few terms requiring definition:

PD = Planned Duration
ED = Estimated Duration
PF(t) = Performance Factor (time-based)

The time-based performance factor is analogous to the PF used in the EVM IEAC equation.
