Example of a critical path

Top  Previous  Next

This is an example diagram with activity cost displays set to show the critical path analysis values.

 

 

 

 

 

 

Early Start (ES) - the earliest possible start time of an activity, relative to the start time of the first activity (i.e. zero).

Late Start (LS) - the latest possible start time without increasing the overall duration of the process

Early Finish (EF) - the finish based on the early start plus the activity duration

Late Finish (LF) - the finish based on the late start plus activity duration

Float - the late start minus the early start (i.e. flexibility on activity duration without increasing the overall process duration)
