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.
- Level of Effort: This type of activity indicates that it is ongoing with a duration determined by its dependent activities. The duration is calculated based on the schedule dates of its predecessors and successors. Administrative activities are typically designated as Level of Effort.
- Start Milestone: This type of activity indicates the beginning of a major project phase. Activities of this type have a duration of zero (0) with no resource assignments.
- Finish Milestone: This type of activity indicates the end of a major project phase. Activities of this type have a duration of zero (0) with no resource assignments.
