Activities in Oracle Primavera P6



Activities represent various items, works and deliverables within a work schedule.

According to PMBOK, an Activity is “ a distinct, scheduled portion of work performed during the course of a project.”

Activities are the basic work elements of a project. An activity is also known as a task, item, or event.

Activities typically have estimated resources, costs and durations. However, milestone activities do not have any duration or cost. Sometimes, activities can be divided into any number of logical steps.

Let’s review the six different types of activity.

Task Dependent



Task Dependent is used when the work needs to be completed in a determined time period, regardless of the assigned resources existence. Task dependent activities are scheduled based on the activity’s calendar, rather than the calendars of the resources.

Resource Dependent

Resource Dependent is used when the work is to be completed depending on the assigned resources existence. In other words, resource dependent activity type can be used when the activity duration may be affected by the availability of resources. Resourcesare scheduled based on their assigned calendars

Level of Effort

Level of Effort is used for activities such as project management, executive,
clerical work, security guard etc. activities. Duration of is Level of Effort is determined by its predecessor/ successor activities.

Start Milestone



Start Milestone is a zero duration activity that only has a start date. It is used to mark the beginning of a phase or an important event.

Finish Milestone

Finish Milestone is a zero duration activity that only has a finish date. It is used to mark the completion of a phase or an important event.

WBS Summary

WBS Summary compromises a batch of activities that have a common WBS (Work Breakdown Structure) level. Start date of WBS Summary is the earliest start date and finish date is the latest finish date of the activities in the group.

Task dependent activities are scheduled based on the working and non-working days of the activity calendar. Resource Dependent activities are scheduled based  on the working and non-working days of the allocated resource’s calendar. The duration of a Level of effort activity is dependent on its predecessor and/or successor activities. Start and finish milestone activities mark important start or finish dates of the project. They don’t have any duration or cost. A WBS summary activity is used to summarize a WBS level. Start date of a WBS summary is the start date of the activities of WBS level and finish date of it is the finish date of the activities of WBS level.
