1. Scheduling
A project schedule is determined through a combination of activity relationships, durations, and constraints. 

2. Critical Path Methodology (CPM)
Primavera Cloud uses the critical path methods scheduling technique to calculate project schedules and determine the minimum total project duration. 

3. Forward Pass
In CPM scheduling, all activities in the network are examined by conducting a Forward Pass from the beginning of the project to the end in order to calculate the earliest start and finish dates for each activity.

4. Backward Pass
The activities are then re-examined in reverse using a Backward Pass to determine the latest start and finish dates for each activity. 

5. Total Float
The difference between an activity's late dates and early dates is known as Total Float. Total float is the amount of time an activity can be delayed from its early start without delaying the project.
Scheduling a project using the critical path method results in what is known as the critical path of the project. This is the sequence of activities that determines a project's minimum total duration and completion date. A delay to any activity on the critical path will delay the finish date of the project.

6. Scheduling Practice Task
To get started, let's go to the Activities page of an open project. Note that before scheduling, all of the project's activities are aligned on the project's planned start date on the Gantt chart. Click Schedule to schedule the project. Select a data date. The data date is the starting point from which all remaining work is scheduled
