Slack in routing refers to the amount of time a task can be delayed without affecting the project schedule.

• Slack allows for flexibility in project timelines

• It is the difference between the earliest and latest start time of a task

• Tasks with zero slack are critical and cannot be delayed

• Slack is calculated using the Critical Path Method (CPM)

• Example: If a task has a duration of 5 days and a slack of 2 days, it can be delayed by 2 days without impacting the project deadline
