8 Contoh Layout PDM - activity on node (E) Early start - the earliest the activity can start (L) Latest start - the latest the activity can start without delaying the project (EF) Early finish - the earliest the activity can finish (LF) Latest finish - the latest the activity can finish without delaying the project
