Activity Relationships:
* Activity 2002 is directly succeeded by Activity 2003 in the schedule.
* The late start (LS) of Activity 2003 determines the late finish (LF) of Activity 2002, adjusted by any lags or additional constraints.
Late Finish Calculation Formula:
* LF of 2002 = LS of 2003 - 1 day.
* This accounts for the predecessor-successor logic and the sequence of activities.
Date Calculation:
* Late start of 2003 = 10-06-01.
* Late finish of 2002 = 10-06-01 - 1 day = 10-05-01.
Verification:
* PSP guidelines emphasize that late finish values are derived by subtracting any relevant time constraints from the successor's late start (Ref: PSP Study Guide, Chapter 2A: Backward Pass Calculations)
