About Activity Types

One of many attributes for an activity, the Activity Type determines how the activity is scheduled according to various scheduling scenarios:

Task Dependent: This type of activity indicates that assigned resources should be scheduled based on the activity's calendar, rather than the calendars of the resources.
Resource Dependent: This type of activity indicates that resources should be scheduled based on their assigned calendars. Use this type when the activity duration may be affected by resource availability.

Start Milestone: This type of activity indicates the beginning of a major project phase. Activities of this type have zero duration.
