Using the normal schedule, what is the early finish date and total float of Activity...

The early finish date and total float are determined using CPM calculations. The PSP Study Guide outlines that early finish is calculated as the early start date plus activity duration, adjusted for calendar constraints (PSP Study Guide, Subchapter 2.2.5, "Constraints and Calendars").

Steps:

Determine early start using forward pass calculations.

Add the activity duration.

Consider non-working days or holidays as per the project calendar.

Calculate float as the difference between late start and early start or late finish and early finish.
