WebSep 3, 2024 · The PERT estimate formula is: Ce = (Co + 4Cm + Cp) / 6. Where Ce = Expected Cost. Cm is the Most Likely Cost. It considers a typical project where everything goes as planned. Cp is the Pessimistic Cost, where almost everything goes wrong. Co is the Optimistic Cost, where everything goes better than presumed. WebFigure 5 shows the three basic cost estimating methods that can be used during a NASA project’s life cycle: analogy, parametric, and engineering build-up (also called “grassroots”), as well as extrapolation from actuals using Earned Value Management (EVM).13 Figure 5 indicates that the prevalent cost estimating methodology changes over ... citylink toll calculator melbourne
