Answer

each ΟΥ LF and EF ES Task EF LS Time LF h = Late start poss is applied to the network, dependencies * Project network IPERTL (PMI AON; is used as a project management tool. It helps to identify project schechult, aidica patha duration & "other information/sesults forward & bartoward with arows, GS, EE, LS, LF & slacks values are calculated.
