Contingency Decision Planner

Set your required confidence level to determine the schedule contingency needed to commit to a target date.

(Baseline Te=40T_e = 40, σp=2\sigma_p = 2)

Required Target Date

Required Z-Score
Z = 1.04
Calculated Contingency
Contingency=Z×σp=1.04×2.0=2.1 days\text{Contingency} = Z \times \sigma_p = 1.04 \times 2.0 = 2.1 \text{ days}
Committed Target Date (TdT_d)
Td=Te+Contingency=40.0+2.1=42.1 daysT_d = T_e + \text{Contingency} = 40.0 + 2.1 = 42.1 \text{ days}
