This statement describes the concept of the latest finish time (LF) and its relationship to the latest start times (LS) of successor activities, as defined by the forward pass calculation in project scheduling. The LF of an activity represents the latest time it can be completed without delaying the project, and is calculated by subtracting the activity duration from the earliest possible end time (EET) of all its successor activities. The LS of an activity represents the earliest time it can start without delaying its successor activities, and is calculated by adding the activity duration to the latest possible start time (LST) of all its predecessor activities. The constraint stated in the question is known as the "finish-to-start" relationship, which is a common precedence relationship used in network diagrams to define the temporal dependencies between activities.
