Forward and Backward pass in Network Diagram, critical path, float/slack time
What is the critical path?
A critical path is a path with least amount of slack/float time.
What is float/slack time?
Float/Slack time is the time that an activity can be delayed without delaying the project.[quads id=1]
When we complete the project through critical path, then it is the longest path as compared to other paths. If any activity is late in the critical path, then it delays all the project. So we need to take care of critical path.
Early Finish = Early Start + Duration
Late Start = Late Finish – Duration
Float/Slack Time = Late Start – Early Start
|Early Start||Duration of activity/task||Early Finish|
|Late Start||Duration of activity/task||Late Finish|
