The Start Slack field contains the duration between the Early Start and Late Start dates. If you want your project to finish on time you can try optimizing tasks that have slack and are not on the critical path. How can I make sure that my project finishes on time? If the critical task is delayed, the project finish date is also delayed. What amount of slack does a critical task have?īy default, a critical task has 0 slack. The Free slack field contains the amount of time that a task can be delayed without delaying any successor tasks and is the difference between the dates in the Early finish and Late finish against the successor. The Total slack field contains the amount of time a task’s finish date can be delayed without delaying the project’s finish date and is calculated as the difference between the Early finish and the Late finish.

If you know where slack exists in your schedule, you can move tasks when certain phases of the schedule have no slack and other phases have too much. The amount of slack in your schedule indicates how long tasks can be delayed before other tasks or the project finish date are affected.
