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)
