Critical Path Scheduling
.....
A scheduling technique whose order and duration of a sequence of task activities directly affect the completion
Critical path: the shortest time in which a project can be completed
Slack time: the time an activity can be delayed without delaying the project
....
PRECEDING ACTIVITIES indicate the activities that must be completed before the specified activity can begin.
...
Determining the Critical Path
...
Calculate the earliest possible completion time for each activity by summing the activity times in the longest path to the activity. This gives total expected project time.
Calculate the latest possible completion time for each activity by subtracting the activity times in the path following the activity from the total expected time. This gives slack time for activities.
Critical path – contains no activities with slack time.
