Critical Paths / Activities (Leaving Cert Applied Maths): Flashcards

Earliest possible moment an event can occur (all previous activities complete)

Latest moment an event can occur without causing project delay

Calculate early times from start to finish

Calculate late times from finish to start

Starting point of project

End point of project

Take largest early time value

Take smallest late time value

How much an activity can be delayed without affecting project completion

$d - a - t$

$d$=late end, $a$=early start, $t$=duration

Activity with zero total float

Sequence of critical activities from start to finish

Minimum project duration

Equals early time
