Correct answer & explanation
✓
Three-point estimating
The correct techniques for estimating activity durations are three-point estimating (A), parametric estimating (B), and analogous estimating (E). Three-point estimating uses optimistic, pessimistic, and most likely estimates. Parametric estimating uses a statistical relationship between historical data and other variables. Analogous estimating uses values from previous similar projects. Reserve analysis (C) is used for contingency reserves, not for estimating durations. Monte Carlo simulation (D) is a risk analysis technique.
