To set the critical path in Microsoft Project, follow these steps:
- Let's start by opening your Microsoft Project file and ensuring you're in the 'Gantt Chart' view.
- Now, navigate to the 'Format' tab in the ribbon (under 'Gantt Chart Tools' when the Gantt Chart is active).
- In the 'Bar Styles' group, find and check the 'Critical Tasks' checkbox. This tells Project to visually highlight your project's critical path.
- Your critical path tasks are now set in red on the Gantt chart.
