Quizplus · Accepted Answer

A critical activity in project management is defined as an activity with zero slack. This means it is an activity that cannot be delayed without affecting the project's overall completion time. Slack or float is the amount of time that a task in a project network can be delayed without causing a delay to subsequent tasks or the project completion date. Therefore, critical activities are those that have no slack and are on the critical path, which is the longest path through a project's schedule.
