Define critical activities
When you schedule your project, you can decide how you want to identify the critical activities.
- Choose Tools, Schedule.
- Click Options.
- In the General tab, select an option to determine the method for defining critical activities.
If you choose Total Float less than or equal to, specify the maximum float time for activities before they are marked critical. You can type a new number and time unit.
If you choose Longest Path, the activities on the longest path in the network are considered critical. In a multicalendar project, the longest path is calculated by identifying the activities that have an early finish equal to the latest calculated early finish for the project and tracing all driving relationships for those activities back to the project start date.
Note
- When you run the scheduler, activities are flagged as critical based on the option you select as described above. If you also choose to calculate multiple critical float paths (on the Advanced tab of Schedule Options), the float paths are calculated after the project has been scheduled. Critical activities that are not part of a critical float path remain tagged as critical.
- If multiple projects are open when you schedule, you must select which project's settings to use when scheduling.
