Project Time Management

Critical path --> longest time path. It should not be delay. Otherwise the whole project will delay.

 

Forward Pass: define the early start and early finish

Backward Pass: define the late start and late finish

 

SS: start to start

FS: finish to start

SF: start to finish

FF: finish to finish

 

ES: early start

LS: late start

EF: early finish

LF: late finish

 

Forward Pass and Backward Pass, the first and last node should be same.

If there is no conditions such as SS, FS, SF, FF, the early start should be same as late start and the early finish should be same as late finish.

 

Float = LS - ES = LF - ES

 

If the float of node is 0, the node should be the critical path
