Honest PERT Scope - PERT: Expected Project Time, Step by Step

PERT expected time is exact arithmetic, not a finish-date promise.

highlighted = computed this step

Expected only

The displayed project time 7 is an expected-time calculation.

\text{expected time}=7

Not probability

This does not compute the probability of meeting a date.

\text{no deadline probability}

Not simulation

This does not simulate finishes, model correlation, or replace schedule risk management.

\text{no simulation or risk replacement}

Honesty note

PERT expected activity times and expected path lengths are model arithmetic. This does not promise finish dates, compute probability of meeting a date, model correlation, or replace schedule risk management. Pixel positions are rounded for layout; every displayed estimate, expected time, and path length is exact.
