Another feature of Enterprise Scheduling is the ability to see the project's critical path i.e. allows you to see which tasks will affect the completion date of the schedule - before you move them!
The critical path is visible via the Task Gantt view of the schedule, and in this instance, scrolling down the bottom of our gantt chart, we can see that we have a ’Final Inspection with Client and Handover’ task as our final task, at the end of our schedule.
Moving up to the top right of the page, we will find the ‘Show Critical Path’ tick box to the right, above the gantt task status colour coding (if you have the status colour coding turned on). 
Any tasks or milestones that are connected to the final task, in such a way that moving said task or milestone would affect the end date of the final task - becomes part of the critical path.
Although turning the critical path on is handy to help you keep an eye on any tasks that may potentially push out the delivery date of your project, it will hide any task status colours on the schedule gant.
